|Extensible Markup Language (XML)|
[CR: 20000706] [Table of Contents]
Several introductory and tutorial articles on the Extensible Markup Language (XML) are referenced in the shorter XML Introduction document. Most articles are accessible online.
"The Extensible Markup Language (XML) is the universal format for structured documents and data on the Web." -- W3C XML Web site, 2000-07-06.
The Extensible Markup Language (XML) is descriptively identified in the XML 1.0 W3C Recommendation as "an extremely simple dialect [or 'subset'] of SGML" the goal of which "is to enable generic SGML to be served, received, and processed on the Web in the way that is now possible with HTML," for which reason "XML has been designed for ease of implementation, and for interoperability with both SGML and HTML." Note that the "HTML" referenced in the preceding sentence (bis) means HTML 4.0 and 3.2 which were in common use as of 10-February-1998, when the XML 1.0 specification was published as a W3C Recommendation. The next version of 'HTML' is expected to be reformulated as an XML application, so that it will be based upon XML rather than upon SGML. As of December 1998, 'Voyager' was the W3C code name for HTML reformulated as an application of XML.
XML was initially "developed by a W3C Generic SGML Editorial Review Board formed under the auspices of the W3 Consortium in 1996 and chaired by Jon Bosak of Sun Microsystems, with the very active participation of a Generic SGML Working Group also organized by the W3C." An XML WG (Working Group) under W3C served initially as an editorial board, which received input from an XML Special Interest Group.
As of late 1998, the XML design effort was re-chartered under the direction of an XML Coordination Group and XML Plenary Interest Group to be carried out in five new XML working groups: XML Schema Working Group, XML Fragment Working Group, XML Linking Working Group (XLink and XPointer), XML Information Set Working Group, and XML Syntax Working Group. These working groups were designed to have close liaison relationships with the W3C's Extensible Style[sheet] Language (XSL) Working Group and Document Object Model (DOM) Working Group.
"Extensible Markup Language, abbreviated XML, describes a class of data objects called XML documents and partially describes the behavior of computer programs which process them. XML is an application profile or restricted form of SGML, the Standard Generalized Markup Language. By construction, XML documents are conforming SGML documents."
"XML is primarily intended to meet the requirements of large-scale Web content providers for industry-specific markup, vendor-neutral data exchange, media-independent publishing, one-on-one marketing, workflow management in collaborative authoring environments, and the processing of Web documents by intelligent clients. It is also expected to find use in certain metadata applications. XML is fully internationalized for both European and Asian languages, with all conforming processors required to support the Unicode character set in both its UTF-8 and UTF-16 encodings. The language is designed for the quickest possible client-side processing consistent with its primary purpose as an electronic publishing and data interchange format." [971208 W3C press release]
"XML documents are made up of storage units called entities, which contain either parsed or unparsed data. Parsed data is made up of characters, some of which form the character data in the document, and some of which form markup. Markup encodes a description of the document's storage layout and logical structure. XML provides a mechanism to impose constraints on the storage layout and logical structure. A software module called an XML processor is used to read XML documents and provide access to their content and structure. It is assumed that an XML processor is doing its work on behalf of another module, called the application. This specification describes the required behavior of an XML processor in terms of how it must read XML data and the information it must provide to the application." [adapted from the Proposal]
Valid XML documents are designed to be valid SGML documents, but XML documents have additional restrictions. The W3C XML WG has published a technical NOTE providing a "detailed comparison of the additional restrictions that XML places on documents beyond those of SGML": see http://www.w3.org/TR/NOTE-sgml-xml for the details. The NOTE also includes an SGML declaration which describes the constraints of XML applicable to an SGML parser. [local archive copy]
[This paragraph is superseded by the technical NOTE 'NOTE-sgml-xml' referenced immediately above.] Features in SGML but not in XML include [as of November 5, 1996]: "Tag omission; The CONCUR, LINK, DATATAG, and SHORTREF features; The "&" connector in content models; Inclusions and exclusions in content models; CURRENT, CONREF, NAME, NAMES, NUMBER, NUMBERS, NUTOKEN, and NUTOKENS declarations for attributes; The NET construct; Abstract syntax; Capacities and quantities; Comments appearing within other markup declarations; Public Identifiers; Omission of quotes on attribute values." For a more recent/complete comparison of features, see the relevant section in the language specification, or "What else has changed between SGML and XML?" in the FAQ, maintained by Peter Flynn.
As of December 1997, the current and former members of the XML WG are: "Jon Bosak, Sun (Chair); James Clark (Technical Lead); Tim Bray, Textuality and Netscape (XML Co-editor); Jean Paoli, Microsoft (XML Co-editor); C. M. Sperberg-McQueen, U. of Ill. (XML Co-editor); Dan Connolly, W3C; Steve DeRose, INSO; Dave Hollander, HP; Eliot Kimber, Highland; Eve Maler, ArborText; Tom Magliery, NCSA; Murray Maloney, Muzmo and Grif; Makoto Murata, Fuji Xerox Information Systems; Joel Nava, Adobe; Peter Sharpe, SoftQuad; John Tigue, DataChannel."
Historically: The W3C SGML Editorial Review Board, as of November 5, 1996, had the following members: Jon Bosak, Sun (firstname.lastname@example.org), chair; Tim Bray, Textuality (email@example.com), editor; James Clark (firstname.lastname@example.org), technical lead; Dan Connolly (email@example.com), W3C contact; Steve DeRose, EBT (firstname.lastname@example.org), editor; Dave Hollander, HP (email@example.com); Eliot Kimber, Passage Systems (firstname.lastname@example.org); Tom Magliery, NCSA (email@example.com); Eve Maler, ArborText (firstname.lastname@example.org); Jean Paoli, Microsoft (email@example.com); Peter Sharpe, SoftQuad (firstname.lastname@example.org); C.

The W3C Extensible Markup Language (XML) 1.0 Specification is the principal document governing the XML standard. Several other W3C specifications are also critical to the understanding and implementation of XML as it is currently used. These specifications are being developed by various working groups, sometimes as part of activity outside the sphere of the XML Activity. Some examples:
- XML 1.0 Specification Errata
- Namespaces in XML
- XML Information Set
- Canonical XML
- Associating Style Sheets with XML Documents
- XML Fragment Interchange
- XML Schema
- XML Linking Language (XLink)
- XML Pointer Language (XPointer)
- XML Base
- XML Inclusions (XInclude)
- XSL Transformations (XSLT)
- XML Path Language (XPath)
- Extensible Stylesheet Language (XSL)
- XML Query
- Document Object Model (DOM)

[February 10, 1998] Extensible Markup Language (XML) 1.0. W3C Recommendation 10-February-1998. Editors: Tim Bray (Textuality and Netscape), Jean Paoli (Microsoft), and C. M. Sperberg-McQueen (University of Illinois at Chicago). Reference: REC-xml-19980210.
[October 06, 2000] Extensible Markup Language (XML) 1.0 (Second Edition). W3C Recommendation 6-October-2000. Edited by Tim Bray (Textuality and Netscape), Jean Paoli (Microsoft), C. M. Sperberg-McQueen (University of Illinois at Chicago and Text Encoding Initiative), and Eve Maler (Sun Microsystems, Inc. - Second Edition). Reference: http://www.w3.org/TR/2000/REC-xml-20001006.
[December 13, 2001] XML 1.1. W3C Working Draft 13-December-2001. Edited by John Cowan (Reuters). Version URL reference: http://www.w3.org/TR/2001/WD-xml11-20011213/. Latest Version URL: http://www.w3.org/TR/xml11/.
Abstract: "The Extensible Markup Language (XML) is a subset of SGML that is completely described in this document. Its goal is to enable generic SGML to be served, received, and processed on the Web in the way that is now possible with HTML. XML has been designed for ease of implementation and for interoperability with both SGML and HTML."
- [October 09, 2000] XML 1.0 Second Edition as W3C Recommendation. The W3C's XML Core Working Group has published a new W3C Recommendation for Extensible Markup Language (XML) 1.0 (Second Edition). Reference: W3C Recommendation 6-October-2000, edited by Tim Bray, Jean Paoli, C. M. Sperberg-McQueen, and Eve Maler. This REC specification follows the earlier publication of a public Review Version. "This second edition is not a new version of XML (first published 10-February-1998); it merely incorporates the changes dictated by the first-edition errata as a convenience to readers. The errata list for this second edition is available at http://www.w3.org/XML/xml-V10-2e-errata. The document abstract, unchanged from the 1998 first edition, appears to validate the hermeneutical theory that a text's intent escapes from the author and passes immediately into the control of the community upon utterance: "The Extensible Markup Language (XML) is a subset of SGML that is completely described in this document. Its goal is to enable generic SGML to be served, received, and processed on the Web in the way that is now possible with HTML. XML has been designed for ease of implementation and for interoperability with both SGML and HTML." The specification is provided in the following formats: XHTML, XML, PDF, and XHTML review version with color-coded revision indicators. See also the (non-normative) "Production Notes" in Annex I: "This Second Edition was encoded in the XMLspec DTD (which has documentation available). The HTML versions were produced with a combination of the xmlspec.xsl, diffspec.xsl, and REC-xml-2e.xsl XSLT stylesheets. The PDF version was produced with the html2ps facility and a distiller program."
- [August 15, 2000] Paul Grosso (Co-Chair XML Core WG) announced that the W3C XML Core Working Group has released a draft of the Extensible Markup Language (XML) 1.0 Second Edition for public review: Extensible Markup Language (XML) 1.0 (Second Edition) Review Version; Reference: W3C Working Draft 14-August-2000. "The second edition is not a new version of XML; it is designed to bring the XML 1.0 Recommendation up to date with the XML 1.0 Specification Errata (first edition)." Reviewers are asked to report errors to the 'firstname.lastname@example.org' mailing list, which is publicly archived. Paul writes: "At this time, we are making two versions of the draft Second Edition available for a four week public review, and all interested parties are invited to review the current drafts and submit comments. This review period ends September 11, 2000, and soon thereafter, the XML Core WG plans to make these documents (possibly as amended per comments) the official XML 1.0 Recommendation Second Edition. All these public review documents are linked from the W3C TR page. The 'plain' draft Second Edition is at http://www.w3.org/TR/2000/WD-xml-2e-20000814.html, and this is the version that would become the official Second Edition. We have also produced a 'review copy' which highlights changes between the first edition and this Second Edition, and it is at http://www.w3.org/TR/2000/WD-xml-2e-review-20000814. This may be provided along with the official Second Edition if it is deemed useful and appropriate, but the 'plain' version is the official one. Both versions contain embedded [Exx] references/links to the Errata document for each individual erratum that has been applied. (If we decide to maintain the 'review' version, we may decide to delete the [Exx] references from the 'plain' one.) Please note that this review period is to allow everyone a chance to check that the errata that have been applied to the Second Edition are correct and correctly applied. Reports of further errata or ambiguities in XML 1.0 are welcome, but they will likely be saved to be considered for possible application to a later edition, not added to this Second Edition." [cache]

Yet this simple basis has spawned scores of specialized sub-languages: for airlines, banks, and cell phones; for astronomy, biology, and chemistry; for the DOD and the IRS.

[CR: 20040102] [Table of Contents]
The XML applications and announced industry initiatives listed below have not been evaluated according to any serious criteria for quality and genuineness. Since the various specifications documents for XML/XLink/XSL are still in some flux, it would often be unfair or difficult to make such a judgment. Obviously, many of these application areas provide exemplary models, having unquestioned integrity and high quality. Some already play a vital role in profitable commercial enterprise. It is also to be expected that some early XML/XLink/XSL applications may be merely demonstrations, toys, proof-of-concept applications; still others might be naive or ill conceived. It may be necessary to regard some of these ideas 'in draft' like some of the specifications documents themselves. The good news is this: Net users are seeing clearly that a fixed tag set (like HTML) is not the solution. . .

W3C Specifications Documentation aka 'XML Spec DTD'
[June 30, 1999] A 'TEI Lite DTD in XML' was made available from the TEI Web site. See the references for TEI - the XML version in a separate document, and the section 'Academic Applications' for background on the SGML version of the TEI DTD.
Channel Definition Format (CDF) is an application of the Extensible Markup Language designed for push technology. The proposal has been submitted to the World Wide Web Consortium.
- Channel Definition Format (CDF) - Main entry
"My Netscape Network (MNN) is a free Netcenter service that lets you create your own My Netscape channel. Create an RDF Site Summary (RSS) 0.9 file that describes your content." See description and references in a separate document. Note 'OCS' below.
In early January 1999, a W3C Working Draft for the Document Object Model (DOM) Level 2 Specification Version 1.0 (WD-DOM-Level-2-19981228) was released. It "defines the Document Object Model Level 2, a platform- and language-neutral interface that allows programs and scripts to dynamically access and update the content, structure and style of documents. The Document Object Model Level 2 builds on the Document Object Model Level 1. Level 2 adds interfaces for a Cascading Style Sheets object model, an event model, and a query interface, amongst others."
On October 1, 1998, the World Wide Web Consortium published the Document Object Model (DOM) Level 1 Specification, Version 1.0 as a W3C Recommendation. "The Document Object Model is a platform- and language-neutral interface that will allow programs and scripts to dynamically access and update the content, structure and style of documents. The document can be further processed and the results of that processing can be incorporated back into the presented page."
The main database entry for the W3C DOM has been moved to a separate document.
"Web Collections are an application of XML - a meta-data syntax that fits easily within the framework of the World Wide Web. Web Collections are an application of XML, the Extensible Markup Language. In addition, Web Collections can be expressed inside HTML documents or on their own. In addition they are stylistically similar to HTML to enable easy authoring. . . Some of the anticipated applications of Web Collections include Web Maps, HTML Email Threading, PIM functions, scheduling, content labeling, and distributed authoring." ["work in progress"]

Netscape Communications announced a new proposed XML application. According to the notice on the Netscape Developer's page: "The Meta Content Framework, or MCF, provides a standard way to describe files or collections of information. A new Netsape document describes how to apply MCF using XML, the Extensible Markup Language."
On January 5, 1998, a new (revised) submission on XML-Data was presented to the W3C by Microsoft, ArborText, DataChannel, and Inso. Reference: W3C Note 05 Jan 1998. Authors: Andrew Layman, Edward Jung, Eve Maler, Henry S. Thompson, Jean Paoli, John Tigue, Norbert H. Mikula, and Steve DeRose. According to the introduction, XML-Data "describes an XML vocabulary for schemas, that is, for defining and documenting object classes. It can be used for classes which as strictly syntactic (for example, XML) or those which indicate concepts and relations among concepts (as used in relational databases, KR graphs and RDF). The former are called 'syntactic schemas;' the latter 'conceptual schemas.' The text of this NOTE thus "provides a specification (XML-Data) for describing and exchanging structured and networked data on the Web. Such exchange is facilitated by schemas defining the characteristics of classes of objects. The objects can be syntactic constructs such as are used in XML instances, or may be more abstract such as are found in databases, information models or directed, labeled graphs. This paper describes an XML vocabulary for schemas. One immediate implication of these ideas is a substantive part of the functionalities of XML document types can now be described using the XML instance syntax itself, rather than DTD syntax. We expect XML-Data to be useful for a wide range of applications, such as describing database transfers or remotely-located Web resources."
[Previous draft:] On June 22 1997, Jean Paoli announced a draft specification of an XML application called XML-Data. The specification is documented in a Position Paper from Microsoft, written by Andrew Layman (Microsoft Corporation), Jean Paoli (Microsoft Corporation), Steve De Rose (Inso Corporation), and Henry S. Thompson (University of Edinburgh), with contributions from Paul Grosso, Sharon Adler, Anders Berglund, François Chahuneau, and Edward Jung. XML-Data is an application of XML for exchanging structured data and metadata on the Internet. The paper outlines a number of XML-Data design features which are not in the MCF specification. The position paper has been sent to multiple working groups in the W3C currently dealing with XML and meta-data."

"XML namespaces provide a simple method for qualifying names used in Extensible Markup Language documents by associating them with namespaces identified by URI." A W3C Working Draft "Namespaces in XML" was published on September 16, 1998 (WD-xml-names-19980916).

The Environmental Resources Information Network (ERIN) and ANZLIC Working Group on Metadata created a version 1 draft DTD using SGML. The ANZMETA DTD Version 1.1 (19th January 1998) now "has been written to conform to the requirements of XML 1.0." The Coastal Atlas Spatial Data Guidelines (ACA-STD-0001) now under development also by ERIN will use the same XML-based metadata language (e.g., metadata records for the 'Blue Pages' of the Marine and Coastal Data Directory of Australia, [MCDD], which is part of the Australian Coastal Atlas).

The design of the XML Metadata Interchange Format (XMI) represents an extremely important initiative. It has a goal of unifying XML and related W3C specifications with several object/component modeling standards, as well as with STEP schemas, and more. Particularly, it would "combine the benefits of the web-based XML standard for defining, validating, and sharing document formats on the web with the benefits of the object-oriented Unified Modeling Language (UML), a specification of the Object Management Group (OMG) that provides application developers a common language for specifying, visualizing, constructing, and documenting distributed objects and business models."
Information on XMI is maintained in a separate document.
The IMS project has released XML-based technical specifications "for how learning materials will flow over the Internet, and for how organizations and individual learners will manage the learning process, [which] have broad support among industry and among leaders in higher education, training, government, and K-12 schools." See "IMS Metadata Specification."
"Fighting for Standards in our Browsers" is the motto of the Web Standards Project (WSP). The Web Standards Project is a collective effort of web developers and end users whose mission is to stop the fragmentation of the web, by persuading the browser makers that common standards are in everyone's best interest." Its goal is to support these core standards of the World Wide Web Consortium (W3C) "and to encourage browser makers to do the same, thereby ensuring simple, affordable access to Web technologies for all." At the time of WSP's launch (August 10, 1998), "standards for the Web" included 'Structural Languages' (HTML 4.0, XML 1.0), 'Presentation Languages' (CSS, XSL), 'Object Models' (Document Object Model 1 Core HTML/XML), and 'Scripting' (ECMAScript).

On January 27, 1998, the submission of a proposal for "HTML Threading: Conventions for Use of HTML in Email" was made to the W3C by Microsoft Corporation, Lotus Development Corporation, and Qualcomm Corporation. Reference: W3C NOTE 05-Jan-1998. The document editor is Eric Berman (Microsoft), and authors include Pete Resnick (Qualcomm) and Nick Shelness (Lotus). According to the press release, the HTML Threading Proposal "outlines how Extensible Markup Language (XML) can be used to enable data-rich features in HTML email applications." The document abstract clarifies: "As [email] messages go back and forth between participants in a discussion, it is interesting to be able to track properties of the text in the message and properties of the message itself, such as who wrote what or what message a quoted excerpt is originally from. This proposal defines a mechanism for embedding this information within an email message in a manner that degrades gracefully to downlevel mail clients." Appendix B of the NOTE provides some sample mail messages using the HTML Threading.

A joint submission was made to W3C on August 13, 1997 by Marimba Incorporated and Microsoft Corporation for a proposed "Open Software Description Format (OSD)." A document 'NOTE-OSD' written by Arthur van Hoff (Marimba, Incorporated), Hadi Partovi and Tom Thai (Microsoft Corporation) bears this abstract: "This document provides an initial proposal for the Open Software Description (OSD) format. OSD, an application of the eXtensible Markup Language (XML), is a vocabulary used for describing software packages and their dependencies for heterogeneous clients. We expect OSD to be useful in automated software distribution environments." The proposed specification has apparently been endorsed by other companies, including "CyberMedia, InstallShield Software, LANovation, Lotus Development, and Netscape Communications." [from Net.Com article]
And: "The goal of the OSD format is to provide an XML-based vocabulary for describing software packages and their inter-dependencies, whether it is user initiated ("pulled"), or automatic ("pushed"). XML (eXtensible Markup Language) provides a general method of representing structured data in the form of lexical trees. Using this data model, markup tags in the OSD vocabulary are represented as elements of a tree. The three basic relationships between elements are parent-of, child-of, and sibling-of. Distant relationships can be formed from recursive applications of the three basic ones."

The Wireless Application Protocol (WAP) Wireless Markup Language (WML) is a markup language based on XML, and is intended for use in specifying content and user interface for narrowband devices, including cellular phones and pagers. . . 'A tag-based display language providing navigational support, data input, hyperlinks, text and image presentation, and forms. A browsing language similar to Internet HTML.'
On August 25, 1997 a submission entitled The HTTP Distribution and Replication Protocol was tendered to the W3C by representatives of Marimba Inc., Netscape Communications Inc., Sun Microsystems Inc., Novell Inc., and At Home Corporation. "The goal of the DRP protocol is to significantly improve the efficiency and reliability of data distribution over HTTP. . . The DRP protocol uses a data structure called an index, which is currently specified using the eXtensible Markup Language (XML). Because the index describes meta data, we anticipate using the Resource Description Format RDF), which was formerly called the Meta Content Framework (MCF), in a future versions of the DRP protocol specification. XML is used in the interim because the RDF standard was not finalized at the time of writing. . . The DRP defines the following new features: (1) Content identifiers, using the existing URI specification, which can uniquely identify a piece of content; (2) An index format which can be used to describe a set of files; (3) A new HTTP header field, Content-ID, which is used to obtain the correct version of a file by specifying a content identifier; (4) A new HTTP header field, Differential-ID, which is used to obtain a differential update for a file."

The Weather Observation Markup Format [or: Weather Observation Definition Format] is an application of XML used to encode weather observation reports. The goal of the OMF system is to annotate and augment standard weather reports with derived, computed quantities, and to re-cast the essential information in a markup format that is easier to interpret, yet completely accurate. The data formats typically used in weather reports ("FM 15-X Ext. METAR, FM 16-X Ext. SPECI, FM 51-X Ext. TAF, etc. [constituting] KAWN, WMO feeds . . .") are both incomplete and suboptimal for some processing objectives. According to a summary from one of OMF's designers, the OMF application thus "uses XML for annotating weather observation reports, forecasts and advisories as issued by Weather Meteorological Organization (WMO), the National Weather Center and Air Force Global Weather Center. Currently, METAR/SPECI observational reports, Terminal Aerodrome Forecasts (TAFs) and SIGMET significant weather aircraft advisories are being analyzed and marked up. The incoming source of data are raw bulletins distributed by KAWN/ADWS or National Weather Service'sGateways. The bulletins are parsed, reports are decoded and stored into a database, which can then be queried. The results of the queries are XML-formatted into OMF documents. It is always possible to reconstruct original reports by stripping away the XML markup. The designers are also working on adding other types of reports - Upper Air reports, regional SIGMETs, AIRMETS, Bathythermographs, PIREPS, etc. The markup system is in actual use "to distribute the most current annotated weather observations, forecasts and advisories; the Navy's Joint Metoc Viewer is one application that can ingest OMF documents and display the corresponding data."

This algorithm has been inspired by the DOM-HASH proposal, but operates closer to the surface string of the document. Elements and attributes are subject to formalization in a way quite similar to the one proposed by DOM-HASH - XML delimiters are represented by binary values and entities are replaced by their actual values. However, formalization happens as elements are acquired. Furthermore, this algorithm has been tailored for explicit support of the XML Namespaces and it takes into account some specifics of this specification (e.g., dsig:eval attribute).

"The BIPS specification includes a protocol for sending payment instructions to banks safely over the Internet and a payment server architecture for processing those payment instructions." On August 24, 1998, a specification for the Bank Internet Payment System (BIPS) was published: Bank Internet Payment System Specification Version 1.0. Public Review Draft, August 24, 1998. Appendix G of the specification supplies the 'XML Structure and Document Type Definition (DTD)'. "BIPS instruction messages and their responses conform to the Extensible Markup Language (XML) standard which can be verified and interpreted by freely available XML parsers." The Bank Internet Payment System (BIPS) is a project of The Financial Services Technology Consortium (FSTC). "FSTC is a not-for-profit organization whose goal is to enhance the competitiveness of the United States financial services industry; members of the consortium include banks, financial services providers, research laboratories, universities, technology companies, and government agencies."
Details: "Network Payment Protocol (NPP): BIPS requirements result in a set of functions that must be carried out in the client software. In order to ensure that the client software interfaces with the payment processing systems at each bank in a standard manner, the NPP has been defined and is described in this chapter. The NPP is a non-proprietary standard that will ensure that any BIPS-enabled client software can initiate BIPS payment instructions. The BIPS model is shown in Figure 4.1. All BIPS messages conform to the World Wide Web Consortium's (W3C's) XML specification. NPP Message Specification, Message Formatting, and Data Encoding: NPP messages will be specified and formatted according to standards described in the XML Version 1.0 specification. XML is a simplified subset of the Standard Generalized Markup Language [SGML, International Standards Organization (ISO) 8879]. XML provides a standard format to describe different types of data so that the information can be decoded, manipulated, and displayed consistently and correctly. XML also provides a file format for representing data, a schema for describing data structure, and a mechanism for extending and annotating Hypertext Markup Language (HTML) with semantic information. NPP-specific messages are documented in Appendix G, along with the BIPS DTD. Some characteristics of NPP messages are: 1) all messages are in XML; 2) all messages start with a BIPS XML header; 3) all fields are self-identifying; 4) all messages are signed; 5) all messages include the originator's certificate; 6) all request messages include a user-supplied transaction number; 7) all response messages include the signature of the user on the original request, and 8) all response messages include both a bank-supplied transaction number and the user-supplied transaction number. BIPS messages contain blocks that describe the request or response (a block is an XML element or conglomerate of elements). Each BIPS message begins with an XML header that includes the XML version number, document type, a reference to the BIPS DTD file, and the BIPS version number. A sample BIPS message is shown in Appendix G."

"The goal of SML (smartX Markup Language) is to enable automation of all interactions with XML documents providing general methods to represent a set of smart device functions. XML supports the creation of marker content that preserves data structure and promises web documents to be "machine-readable". The SML is an implementation of XML for the smart card industry. SML also brings to the smart device applications many IDL features that have been implemented in distributed computed and transaction processings.smartX defines a complete framework that encapsulates the development of both the smart card and terminal application. By separating the application process from the application protocol that is card-specific, smartX makes possible to port quickly an application to a new smart card. The innovation of smartX technology relies on a strong description of the smart device data and attached processes. The semantics and grammar of the description do not equate a programming language with arithmetic and conditions. On the contrary, the data and protocol description is built upon the familiar foundations of the smart card industry, which simplifies programming for the developer. smartX introduces a new description language to describe the application protocol: SML (Smart Markup Language) that implements the Extensible Markup Language (XML) for the smart card industry."

Founded in 1992, the Customer Support Consortium is "a group of over 70 leading technology companies who work together to significantly improve customer support by developing innovative new strategies, standards, and programs. Its mission is to develop ways to leverage and share knowledge within and among support organizations." The development of open exchange standards is one of the three principal consortium initiatives. A subgroup is developing a set of mappings from standards specifications to XML.
In response to requirements from the 1990 US Clean Air Act, The Society of Automotive Engineers (SAE) has adopted a number of standards under the 'SAE J2008' family of standards designed to "provide easy access to emission-related automotive service information. At the heart of this SGML standard is a relational Data Model for Automotive Service Information rather than any particular document model. The SGML definition set forth within J2008 provides a hierarchical representation of the Data Model. In addition, this standard provides models for common text constructs such as tables, paragraphs, lists, and procedures which are found within automotive service information." Recently, as explained by Dianne Kennedy in the presentation "XML and the Automotive Industry" (XML the Conference 98, Seattle 1998), effort has been made to convert the SGML DTD into a version compatible with XML. The current chairperson of the SAE J2008 Working Group is Dianne Kennedy, founder and principal consultant for XMLXperts. [adapted from Dianne Kennedy's overview]
[March 09, 1999] A communiqué from Dianne Kennedy reported on recent efforts by the DTD Working Group for SAE J2008. The Society of Automotive Engineers (SAE) J2008 DTD Working Group met on March 3, 1999 in Detroit. Among the work items was the development of an official" XML version of the SAE J2008 DTD for posting automotive service information on the Web. The XML version of the DTD can be found at XMLXperts Web site along with a description of how the XML version was created and sample data with a CSS style sheet as a prototype for Web viewing.

[May 04, 1998] On May 4, 1998, an announcement was issued by DataChannel and OASIS concerning X-ACT: "DataChannel Transfers X-ACT Council to OASIS. XML Market Receives Enhanced Services Through Vendor-Neutral Management of Leading Industry Council." According to the press release, "OASIS, the Organization for the Advancement of Structured Information Standards (formerly SGML Open), announced today that it will take the helm of the XML Active Content Technologies Council (X-ACT) to provide vendor-neutral management and enhanced industry services."
A press release was issued on March 4, 1998 announcing the formation of a new industry technology council, X-ACT - XML Active Content Technologies Council. "X-ACT is an industry council formed to provide a communications venue for corporations working to develop real-world XML-based solutions to meet today's business needs, increase awareness about Active Content Technologies and their benefits, and maintain an index to Active Content software. Aligned with all standards bodies, X-ACT specifically focuses on promoting the usage and adoption of XML in real-world applications. . . Active Content represents all the possible forms of XML as documents, data and meta-data, and the new class of information systems that will allow data or objects to be re-used and re-purposed by any application." The new industry group recognizes that XML, "a groundbreaking new technology, will spawn a new class of computer applications and transactions (Active Content Technologies) that will enable active content at all levels of networked computing (Desktop, Server, Internet, Intranet, Extranet, VPNs, LANs, WANs). The eighteen (18) members include, to date: Allaire, Andersen Consulting, Arbor Text, BTG, DataChannel, Daylight Software, Informix, Inso, NexGen SI, OmniMark Technologies, Online Computing Library Center, PLATINUM Technology Solutions, Poet Software, NC Focus, Sybase, Thomson Corporation, Wall Data and WebMethods.

The Mathematical Markup Language (W3C Working Draft) is a specification which "defines the Mathematical Markup Language, or MathML. MathML is an XML application for describing mathematical notation and capturing both its structure and content. The goal of MathML is to enable mathematics to be served, received, and processed on the Web, just as HTML has enabled this functionality for text. The document begins with background information on mathematical notation, the problems it poses, and the philosophy underlying the solutions MathML proposes. MathML can be used to encode both mathematical notation and mathematical content. About 25 of the MathML tags describe abstract notational structures, while another 75 provide a way of unambiguously specifying the intended meaning of an expression. Additional chapters discuss how the MathML content and presentation elements interact, and how MathML renderers might be implemented and should interact with browsers. Finally, the document addresses the issue of MathML entities (extended characters) and their relation to fonts."
[February 24, 1998] MathML (Mathematical Markup Language) specification issued by W3C as a Proposed Recommendation. Editors: Patrick Ion and Robert Miner. Reference: PR-math-19980224. Abstract: "MathML is a low-level syntax for representing structured data such as mathematics in machine-to-machine communication over the Web, providing a much-needed solution for including mathematical expressions over the Web. In developing MathML, the goal was to define an XML-compliant markup language that describes the content and presentation of mathematical expressions. This was achieved with MathML. As an effective way to include mathematical expressions in Web documents, MathML gives control over the presentation and the meaning of such expressions. It does this by providing two sets of markup tags: one set presents the notation of mathematical data in markup format, and the other set relays the semantic meaning of mathematical expressions, enabling complex mathematical and scientific notation to be encoded in an explicit way. As an XML application, MathML capitalizes on XML features and benefits from the wide support of XML. Unlike HTML which was intended as a markup language for use by people, MathML is intended to be used by machines, facilitating the searching and indexing of mathematical and scientific information. Software tools that work with MathML render MathML into formatted equations, enabling users to edit mathematical equations much as one might edit HTML text. Several early versions of such MathML tools already exist, and a number of others, both freely available software and commercial products, are under development." See the press release.

"CDIF (CASE Data Interchange Format) attempts to address a problem faced by both users and vendors of Visual Modeling tools and Computer Aided Software and Systems Engineering (CASE) tools: interoperability. Users need to be able to move information from one CASE tool to another in order to develop systems efficiently. They need to move information from a tool to a repository and back. They need to exchange data between repositories."
"CDIF is a Family of Standards that lays out a single architecture for exchanging information between modelling tools, and between repositories, and defines the interfaces of the components to implement this architecture. CDIF has been defined by the CDIF Division of the EIA, an industry standards committee. CDIF is also being standardized at an international level through ISO/IEC JTC1/SC7/WG11. Many of the major modeling, CASE and repository vendors, and some large user organizations have pooled their expertise and resources to develop this Family of Standards. Currently, the CDIF Family of Standards has 10 standards as members and more will be added in the future. The CDIF standards development process is open-ended, and driven by the interests of the CDIF member organizations. Any organization can become a CDIF member and thus influence current and future CDIF work."
The CDIF Technical Committee is preparing a specification called the CDIF XML-based Transfer Format. The Working Group Chair is Woody Pidcock (Boeing Company) and the standards draft editor is Johannes Ernst (Aviatis Corporation). A June 1998 draft (CDIF-DRAFT-XML-V3, EIA-PN-XXX, CDIF XML-based Transfer Format, EIA/CDIF 1998) edited by Johannes Ernst outlines the ongoing work of the CDIF Technical Committee on the transfer format. "The CDIF (CASE Data Interchange Format) family of Standards is primarily designed to be used as a description of a mechanism for transferring information between CASE tools. It facilitates a successful transfer when the authors of the importing and exporting tools have nothing in common except an agreement to conform to CDIF. The language that is defined for the Transfer Format also has applicability as a general language for Import/Export from repositories. The CDIF Integrated Meta-model also has applicability as the basis of standard definitions for use in repositories." The XML-based CDIF Syntax which "allows the exchange of meta-models and models using the emerging XML standard" is being provided in addition to the CDIF Transfer Format based on SYNTAX.1 and ENCODING.1."
In the version 3 draft document, (Section 5.2 of the Transfer Format Overview), the relationship of the CDIF Transfer Format to XML is explained: "The primary application of the XML standards is document markup. Compared to the HTML document type definition, XML-based document type definitions allow for a more strict definition of the content and content structure. On the other hand, the exchange of modeling information according to the CDIF architecture requires an even stricter set of rules to be followed than even in a strict application of XML. This has two consequences: (a) any CDIF Transfer file employing the XML-based CDIF Transfer Format is also a legal XML file; (b) the rules to be followed by files employing the XML-based CDIF Transfer Format cannot be fully captured in an XML DTD alone; instead, this standard defines rules that are mandatory for such an XML-based CDIF Transfer beyond those defined in the DTD. As an example for the latter, consider the rich set of data types for meta-attributes and meta-meta-attributes required to exchange modeling information, and compare them to the significantly smaller set of data types provided by XML. When exchanging models with the XML-based CDIF Transfer Format that employ any of the richer data types, additional rules have to be obeyed."

On April 03, 1998, a submission was made to the World Wide Web Consortium concerning a proposed Precision Graphics Markup Language (PGML). References: W3C NOTE-PGML-19980410, World Wide Web Consortium Note 10-April-1998, URL http://www.w3.org/TR/1998/NOTE-PGML-19980410. The W3C NOTE was submitted by representatives of Adobe Systems Incorporated, International Business Machines Corporation, Netscape Communications Corporation, and Sun Microsystems, Inc. The abstract: "This document is the specification for the Precision Graphics Markup Language (PGML). PGML is a 2D scalable graphics language designed to meet both the simple vector graphics needs of casual users and the precision needs of graphics artists. PGML uses the imaging model common to the PostScript(R) language and Portable Document Format (PDF); it also contains additional features to satisfy the needs of Web applications." The NOTE is characterized as "a working document. It is not meant to be a complete definition for PGML. Many sections have been left open or have been labeled Ideas for Consideration so that the working group can develop the strongest possible language specification and ensure that it is fully compatible with other W3C standards efforts."
Among the 'Design Principles': PGML should be an XML application and the imaging model is an instance of the RDF data model. . . PGML should be compatible with and fully leverage all related W3C standards efforts. . .in particular, PGML will be an application of XML. . .[provision for ] exporting the imaging model to the DOM." A W3C 'Comment on PGML Submission' asserts: "PGML is expressed in XML, which allows PGML graphics to be modified with style sheets along with the document in which they are contained." A sample from Appendix B (minus the pretty-printing):

On May 28, 1998, the W3C acknowledged receipt of a submission for a proposed Vector Markup Language (VML) from Autodesk Inc., Hewlett-Packard Company, Macromedia, Inc., Microsoft Corporation, and Visio Corporation. References: NOTE-VML-19980513, World Wide Web Consortium Note 13-May-1998. The submission defines the Vector Markup Language (VML), which "is an application of Extensible Markup Language (XML) 1.0 which defines a format for the encoding of vector information together with additional markup to describe how that information may be displayed and edited." According to the Introduction in the NOTE, "The Vector Markup Language (VML) supports the markup of vector graphic information in the same way that HTML supports the markup of textual information. Within VML the content is composed of paths described using connected lines and curves. The markup gives semantic and presentation information for the paths. VML is written using the syntax of XML just as HTML is written using the syntax of SGML (the Standard Generalized Markup Language, [ISO 8879]) - XML is a restricted form of SGML. VML uses Cascading Style Sheets, Level 2 in the same way as HTML to determine the layout of the vector graphics which it contains." Normative references cited in the NOTE include HTML 4.0, CSS1/2, XML 1.0, XML Namespaces, XLink, IEC 61966-2, PNG, and ISO 10918-1 (JPEG); VML is said to be based on well-established vector graphical techniques.
From the W3C Comment on the VML Submission: "VML is expressed in XML, which allows VML graphics to be modified with style sheets along with the document in which they are contained. The submitters have clearly given thought to style sheet binding, to the necessary stylistic differences between editors and viewers, and to containment in HTML; they have also taken care to address the points in the W3C Requirements document."

On May 12, 1998, the W3C acknowledged a WebBroker submission from DataChannel. DataChannel, Inc. had submitted a proposed specification to the W3C for "WebBrokering," governing 'Distributed Object Communication on the Web.' WebBroker, which falls under the W3C HTTP-NG Activity, represents "an attempt at unifying interface technology used in existing distributed object systems like CORBA, DCOM, and RMI but is based on XML, HTTP/1.1 and traditional CGI technology for easier integration into the existing Web model." The submission is composed of five separate documents:
- "WebBroker: Distributed Object Communication on the Web" (NOTE-webbroker-19980511, authored by John Tigue and Jon Lavinder)
- "ObjectMethodMessages DTD"
- "AnonymousData DTD"
- TerseAnonymousData DTD
- "InterfaceDef DTD."
The abstract: "This document provides a specification (WebBroker document type definitions, or WebBroker DTDs) for describing and exchanging structured messages between software components on the Web. Such exchange is facilitated by the DTDs which describe the structure of the messages (method requests and method responses) and which also describe the interfaces of the software components themselves. The AnonymousData DTD describes a simple way of expressing the data type of structures which works within XML 1.0 and is designed to work with XML-Data. The ObjectMethodMessages DTD describes how to represent, in XML documents, the serialized messages between software components. ObjectMethodMessages uses the AnonymousData DTD and is modeled after DCE RPC Request and Response PDUs. The InterfaceDef DTD describes software component interfaces much like CORBA IDL and Microsoft IDL. One immediate implication of these ideas is that there can now be a unified Web publishing and traditional client/server programming model which work over HTTP 1.1. We expect the WebBroker DTDs to be useful for enabling many organizations to implement a mature yet simple and easy to reproduce model of distributed computing on the Web."

XML and EDI (Electronic Data Interchange). "EDI works by providing a collection of standard message formats and element dictionary in a simple way for businesses to exchange data via any electronic messaging service. . . XML/EDI provides a standard format to describe different types of data -- for example, a loan application, an invoice, healthcare claim, project status -- so that the information can be decoded, manipulated, and displayed consistently and correctly by implementing EDI dictionaries. Thus by combining XML and EDI we create a new powerful paradigm!" (Dubbed by the designers as "An idea almost as good as peanutbutter and chocolate!")
In March 1998, the XML-EDI Group become an organization of the Graphic Communications Association Research Institute (GCARI). GCARI, "an affiliate of Graphic Communications Association (GCA) in Alexandria, Va. GCA is a technical management association in the publishing and printing industries that has supported XML since its creation."

According to a press release of July 27, 1998, the objectives of the working group are to: "1) Develop draft standards on repositories for submission to the World Wide Web Consortium (W3C), Object Management Group (OMG), and UN/EDIFACT working groups; 2) Establish a formal working group to coordinate proposal development; 3) Provide a technical forum for individuals involved in repository development to participate; 4) Offer links among disciplines and standards such as W3C's XML, as well as OMG's UML (Unified Modeling Language) and MOF (Meta-Object Facility); 5) Provide a means for vendors who have announced products based on open standards on this topic to offer their ideas. The first draft is anticipated for an availability date of September 30, 1998. For the purposes of this discussion group, the term "EDI" shall include business-to-business, business-to-consumer, and consumer-to-business exchanges of XML formatted and structured data or information."

"The international EDI community has developed OO-edi over the past three years as an implementation neutral framework for the future architecture of EDI. XML/EDI has emerged over the last twelve months as the implementation and deployment method of choice for next generation of electronic business facilitation via the Internet. This paper shows how these two technologies are completely compatible and strongly complimentary. XML/EDI emerges as the implementation method of choice for FVS (Functional Service View) of Open-edi, and Open-edi BOV (Business Operational View) provides the means to underpin the physical implementation methods of XML/EDI with design, process and logic verification to ensure robust and efficient systems development and architectures. Two representation methods provide the link between the two: Universal Model Language (UML), and Extensible Markup Language (XML).

"The EEMA EDI Work Group would like to propose to CEFACT the establishment of a Global Repository for the translation of XML tags in UN/EDIFACT and human language on the Internet. The EEMA EDI Working Group is prepared to assist in the set up and operation of such a repository, which could be crucial in the advancement of the use of EDI over the Internet. . . . When the fusion between ANSI X12, EDIFACT and all other EDI standards takes place in a proper way it should be under the auspices of the UN so it is global, public domain, open and available for anyone. Today this is not the case with the ANSI standards and many other EDI standards that are only available at considerable cost. Of course today the EDIFACT standard is already in the public domain and can easily be obtained through the Internet."
". . .there could be a relatively easy fusion between EDIFACT and ANSI X12. Essentially every data-element one can find in ANSI or in EDIFACT could be placed inside the XML/EDI file. What would be required is to set up a repository in which the tags for the XML files are listed with the corresponding EDIFACT data-element number, the corresponding ANSI X12 element number, and a description. . . By setting up one global repository on the Internet, CEFACT can assume responsibility for the creation of new tags based on a corresponding EDIFACT data-element number and the standard description, while other organizations can assume responsibility for a language code or the corresponding element number in different standards. Even if XML/EDI is not the ultimate solution, a global repository would be extremely useful for conventional EDI and other forms of EC, because it would provide an independent Data Dictionary which could be used by applications."

IETF Internet Draft draft-kristensen-xml-map-00.txt. By Anders Kristensen. Hewlett-Packard Laboratories. "This document proposes an XML encoding for sets of named values. The primary application is as a transmission format for form values being submitted to a processing agent over the Web. The main advantage over other form value encodings is that it allows field names to be associated with structured values without resorting to non-XML encodings. The multipart/related MIME type is used for carrying non-XML media."

This IETF INTERNET DRAFT for a 'Capability Card' "describes basic ideas and data components of 'Capability Card,' which is a kind of attribute certificates designed from the standpoint of a secure communication framework on the Internet. Similar to the SPKI certificates, a capability card can be used to grant a person particular access privileges to resources like WWW pages, IRC channels, and message boxes. In addition, it can carry a variety of descriptive information about the issuer, the resources, and the privileges specified in it. A capability card is written in XML, which is becoming a standard format rapidly for the internet data exchange. Consequently, users can handle various information in capability cards visually with an XML viewer. This is a fairly desirable feature for the existing internet services. In this document, following the motivation and the basic concepts, the elements of XML DTD of capability cards are described."

The recent revision of the TIM DTD toward version 2 has been motivated, in part, by a desire of the subcommittee to make this news industry DTD XML compliant. "Information Products Interchange (IPI) is a working committee of the Telecommunications Industry Forum. IPI was established to select standards and guidelines capable of allowing the interchange of a variety of information products for the telecommunications industry . . . Most of the IPI Committee's published work has to do with the Telecommunications Interchange Markup (TIM, an SGML DTD) and the Telecommunications Electronic Document Delivery Package (TEDD)."
"The TIM Document Type Definition (DTD) is a specification for describing the structure of telecommunications and other technical documents . . . based largely on early versions of the DocBook DTD developed by the Davenport Group. TIM 1 was approved as a TCIF Guideline in December 1995, and revisions for TIM 2 were begun in December 1996. As described in the TCIF Information Publication TCIF-IPI-97-004 (Issue 1, 10/24/97), several of the DTD changes were aimed at making the TIM 2 specification XML compliant. These included changes to the SGML declaration, removal of inclusion and exclusion exceptions from content models, implementation of external cross-references through URLs, restricting the attribute data types to the XML-valid AttType values ('TokenizedType' -- in particular, NMTOKEN for NAME, NUMBER, and NUTOKEN), and restriction of PCDATA to content models having repeatable 'OR groups'. Thus: "except for changes to adapt to the not-yet-finished XLL linking specification, TIM is already XML-complaint and ready for the next generation of browsers."

The US Library of Congress and several research level institutions have been engaged in the collaborative work of the EAD (Encoded Archival Description) initiative for several years. These institutions use the EAD DTD, and currently encode their archival finding aids using the Standard Generalized Markup Language (SGML) or in XML. The EAD Document Type Definition (DTD) represents the formal part of a standard for encoding archival finding aids using the Standard Generalized Markup Language (SGML) and the Extensible Markup Language (XML). This standard is maintained by the Network Development and MARC Standards Office of the Library of Congress (LC) in partnership with the Society of American Archivists

A communique from Junichi Suzuki (The Graduate School of Computer Science, Keio University) describes an XML application proposed as the UML eXchange Format (UXF). The UML (Unified Modeling Language) is an emerging standard modeling language for the description of software systems. "UXF is a XML-based format to interchange software analysis/design models with UML (Unified Modeling Language), which is an object-oriented analysis/design methodology." According to the description on the UXF Web site, the project "addresses how UML (Unified Modeling Language) models can be interchanged and proposes an application-neutral format called UXF (UML eXchange Format), which is an exchange format for UML models based on XML (Extensible Markup Language). It is a format powerful enough to express, publish, access and exchange UML models, and a natural extension from the existing Internet environment. It serves as a communication vehicle for developers, and as a well-structured data format for development tools. With UXF, UML models can be distributed universally." UXF is thus expected to support intercommunications between software developers, interconnectivity between development tools, and a natural and transparent extension from the existing Web environment. Several related DTDs are now available or in draft: Parent DTD for all subset DTDs, DTD for class diagrams, DTD for collaboration diagrams, DTD for statechart diagrams, UXF DTD for sequence diagrams. The designers are using 'XSL' stylesheets for UXF data.

"In the software engineering community, Unified Modeling Language (UML) has been widely accepted as an object-oriented software analysis/design methodology, since it provides most of the concepts and notations that are essential for documenting object oriented models. UML, however, does not have an explicit format for interchanging its models intentionally.

"This paper addresses a standard-based UML model interchange and presents our effort to make UML interoperable. We developed a XML-based exchange format called UXF (UML eXchange Format) and a distributed model management system for UML. The system leverages the team development, reuse of design models and tool interoperability by interchanging the model information with XML through the Document Object Model (DOM) interface that is implemented on top of CORBA (Common Object Request Broker Architecture).

"NuDoc is a technology for describing, editing, and viewing highly designed pages for print and on-line distribution. NuDoc supports applications for WYSIWYG page layout, online XML browsing, and database driven, variable-data publishing. In NuDoc, a document object is made of style, content, and page layout sub-objects. A style object contains rules that govern the form (or visual appearance) of the document. Content elements such as words, images, movies, etc. are organized into a tagged tree structure that represents the logical organization of the information (sections, sub-sections, etc.). The W3C's Extensible Markup Language (XML) is the default content data representation."
"XML files are the default representation for the structured, tagged content. NuDoc reads and writes XML content files during the authoring process. NuDoc's TSL files are used to define the style sheets. For rapid saving and restoring of the entire document object's state, NuDoc can save to disk (and re-read) the post-composition document containing the style, content, and resulting page layouts (including all user edits and mark-up) to an external XML-format checkpoint file. Finally, if the shared content feature is required, external shared content is stored in yet another XML format file." [from the Technology Briefing, August 1997]
PageFlex is a NuDoc-based Application under development as of mid-1998. "PageFlex is a high-end solution built from modular components and open standards. It is the first solution to use XML as the intermediate data format between databases and the page composition process. The output formatter is based on Bitstream's revolutionary NuDoc page composition engine, NuDoc offers unprecedented control over the graphic design of page templates while maintaining a strict separation of form from the input XML content."
Coins is a programming project undertaken by Bill la Forge. Description: "A coin has two faces, an XML element and an instance of a JavaBean: a) the XML element is the persistent form, an b) the JavaBean instance is the runtime form. One of the primary operations of a coins program is the binding of XML element types to specific Java classes. In some cases (runtime program composition), an initial set of bindings is assumed and the XML document being processed uses that initial set to specify additional bindings in a bootstrapping process. The bindings used to process a document are not always fixed, but are often determined by the application or server processing the document. In these cases, the XML document is simply a vehicle for moving information between applications, and the coins technology simply provides the means for processing that document. A particularly interesting feature of coins is its use of hyper-links. Java serialization has no equivalent capability, forcing the .ser files generated by Java serialization to be self-contained. . ."

On June 12, 1998, Jeffrey Ricker posted an announcement for an initial design of PIF-XML (Process Interchange Format XML). PIF is "an interchange format designed to help automatically exchange process descriptions among a wide variety of business process modeling and support system such as workflow software, flow charting tools, process simulation systems, and process repositories." PIF itself "is based on the Knowledge Interchange Format (KIF), which is in turn based on LiSP. Since both LiSP and XML are text-based and nested trees, the translation is relatively straightforward. However, PIF also includes an object-oriented design with inheritance, which does not directly translate into XML." The initial work attempts a direct translation of PIF version 1.2, and is not optimized for economy in XML; a provisional DTD and example encoded PIF-XML document are available.

"QAML is a new language created using XML. The purpose of QAML is to provide a more specific format for documents dealing with questions and answers. Why use QAML instead of HTML? Because unconstrained HTML is too powerful and loose! In particular QAML is meant for FAQs, or Frequently Asked Questions. QAML was originally meant to be a broader language, but we have decided to focus it specifically on FAQs. We are programming a CGI which will format QAML documents and convert them to HTML, so it will be possible to implement QAML without having to worry about when XML browsers are commonplace.

Principal investigators include Boyd Michailovsky, John B. Lowe, and Michel Jacobson. The 'Projet Archivage de données linguistiques sonores et textuelles', under the auspices of the larger LACITO programme (Laboratoire de langues et civilisations à tradition orale) and direction from CNRS, concentrates on the encoding, archiving, and distribution of speech data, particularly for rare languages that are researched within the unit. "The main source of data for the project is the mass of documents recorded and transcribed in the field by members of the LACITO over the last thirty years. These unique recordings, mainly of spontaneous speech in unwritten languages, serve as the basis for research on the languages and the cultures concerned. Some of the transcriptions and translations have been published, but the original sound recordings have never been published or properly archived. . . An explicit XML (Extensible Markup Language) markup has been adopted for the text materials. In many cases, older documents whose structure is implicit are marked up automatically by program." The interlinearized text (annotated and glossed) is displayed using XSL stylesheets. Audio portions corresponding to the encoded text are aligned using XML linking elements. . .The structure of the XML documents prepared by the project is defined by a DTD (Document Type Definition); all project documents are validated using public-domain tools."

GedML is "a way of encoding genealogical data sets in XML. It combines the well-established GEDCOM data model with the new XML standard for encoding complex information. The result is a representation that can easily be converted to and from GEDCOM, but can be manipulated much more easily using standard tools." See now the document Genealogical Data and XML for information on GedML and other specifications using XML for genealogical information.

As of January 1999, a News Markup Language (NML) was under development through the effort of the American Press Institute's Media Center. In a meeting of April 1999, it was decided to incorporate the requirements for NML into the NITF design and development work. Further information is provided in a separate document.
An announcement for a new XML application initiative (Notes Flat File Format Initiative) was posted by Sean McGrath on May 14, 1998. "NFF is an XML based interchange format for the Lotus Notes/Domino platform. The NFF DTD supports the majority of the constructs that can occur in Lotus Notes data such as structured fields, rich text, doclinks, import objects and so on. Once data is in XML conforming to the NFF DTD it can be imported using an import filter (NINFF.DLL) into Lotus Notes using a simple 'File-Import'. The download package includes the necessary software along with a sample application - Timon Of Athens by William Shakespeare in NFF format."

Java Help API: "The structure of a HelpSet is XML-encoded (Extensible Markup Language) data. . ." See Byte Magazine (May 1998) page 108, sidebar "So, Help Me, Java." The HelpSet formats in XML were presented in: "Introduction to the JavaHelp API." By Eduardo Pelegrí-Llopart, Roger Brinkley, and Nancy K. Lee (Sun Microsystems, Inc.) Presented at JavaOne (Sun's 1998 Worldwide Java Developer Conference).
"So, Help Me, Java." From Byte, May 1998: ". . . The new Java Help API, currently in beta testing, is an all-Java 'über alles' help system for JavaBean components, applications, desktops, and HTML pages. . . [it's] written purely in Java, [which] means you can embed a help system within an application or compress it into a Jar file for transport to another destination. . . Java Help permits a single help system to support varying "navigational views" of help content. . . The data structure that carries all the information needed to provide a view into a help system is bundled into a HelpSet file. Note that there are two "loose" terms at use here. First, a HelpSet file isn't necessarily a file, in the same sense as files that you store on your hard disk. A HelpSet file could be bound into an application, for example. Second, it's probably more accurate to say that the information is rooted in the HelpSet file. The structure of a HelpSet is XML-encoded (Extensible Markup Language) data. The data points to the URLs from which you can find the info necessary to build the help system."
"Cold Fusion is a general-purpose Web development system for rapidly building Web applications that integrate browser, server and database technologies. It consists of the Cold Fusion Markup Language (CFML), the Cold Fusion Application Server (NT & UNIX) and the forthcoming Cold Fusion Studio, a visual tool for building dynamic Web applications. . . In essence, CFML provides a generalized markup language for handling the richness of programming, logic and integration required to build full-scale applications on the Web platform. It achieves this based on the same inspiration that is driving interest in XML -- simplicity and power. . . Syntactically, Custom Tags are XML compliant custom markup language elements that allow developers to build reusable components that can be easily dropped into a dynamic Web application. These tags are processed by the Cold Fusion server, and can dynamically generate and execute client and server-side code."

- [August 04, 2000] "ColdFusion Markup Language." By Mark Cyzyk. In WebTechniques Volume 5, Issue 8 (August 2000), pages 74-77. "Consider the selection of server-side scripting languages: The big contenders in this arena are Active Server Pages (ASP) and JavaServer Pages (JSP). Hypertext Preprocessor (PHP) is also starting to edge in on the market. While each is powerful in its own way, neither of the environments is particularly aesthetic by Gelernter's definition. Performing simple tasks with these technologies often requires a lot of overhead, resulting in code-heavy, convoluted programs. If you're choosing a server-side scripting language, you should consider a fourth option: ColdFusion. Because it acts more like a markup language than a programming language, ColdFusion is an elegant solution for embedding code in HTML files. Allaire, the company that also makes the popular HomeSite HTML editor, has a whole suite of ColdFusion technologies consisting of an application server, an integrated development environment, and of course, the markup language. It is this ColdFusion Markup Language (CFML) that competes directly with ASP and JSP. Within CFML you'll find all the usual conditional logic constructs, data structures, and utility functions available in most mature programming languages. Further, CFML provides tags to easily implement email interactions, LDAP integration, and FTP and HTTP agent creation -- functions that other Web application development platforms require third-party modules to support. Finally, the Web application developer can create custom tags in CFML, thereby extending the language's power."

[August 10, 1998] International Business Machines Corporation (IBM) and Microsoft Corporation have submitted a proposal to the World Wide Web Consortium defining a vocabulary for describing constraints upon XML documents: "Document Content Description for XML." References: NOTE-dcd-19980731, Submission to the World Wide Web Consortium 31-July-1998. The document "proposes a structural schema facility, Document Content Description (DCD), for specifying rules covering the structure and content of XML documents. The DCD proposal incorporates a subset of the XML-Data Submission and expresses it in a way which is consistent with the ongoing W3C RDF (Resource Description Framework) effort; in particular, DCD is an RDF vocabulary. DCD is intended to define document constraints in an XML syntax; these constraints may be used in the same fashion as traditional XML DTDs. DCD also provides additional properties, such as basic datatypes. The abbreviation 'DCD' is used to describe both the general facility described in this document and individual schema instances that conform to it." Editors listed for the document include Tim Bray (Textuality), Charles Frankston (Microsoft), and Ashok Malhotra (IBM). Other credits: The specification "has benefited greatly as a result of input from David Fallside and David Singer, both of IBM, Andrew Layman and Jean Paoli both of Microsoft, and from Lauren Wood of SoftQuad. We also wish to thank Henry Thompson of the University of Edinburgh and all the authors of the XML-Data specification."

XSchema is the name of a collaborative effort hosted on the XML-DEV mailing list. The principal goal of the XSchema project is to produce an XSchema specification which, "when complete, will provide a means for XML developers to describe their XML document structures using XML document syntax." The target date for a complete initial XSchema 1.0 proposal is June 30, 1998. As of June 1, 1998, discussion had resulted in the creation of a list of twelve XSchema Goals, as refined through four draft documents. This XSchema work was initiated by Simon St.Laurent with the publication of a paper "A Proposal for the Representation of XML DTDs as XML Documents" and by several supportive postings, including a position paper authored by Paul Prescod. During the initial period of discussion on XML-DEV, the project proposal went under the name XSD (Extensible or XML Structure Definitions).
[November 03, 1998] Simon St.Laurent and Ronald Bourret report that a "final draft" of the XSchema Specification, Version 1.0 is now available (November 1, 1998). Public comments on the draft should be posted to the XML-DEV mailing list. General information on the XSchema project is available at http://purl.oclc.org/NET/xschema.
Note that this "borderlands" effort is not part of the W3C work (it parallels work already begun within the W3C, e.g., XML Data). Its authors declare that "XSchema is not intended to compete with proposals from the World Wide Web Consortium," and they envision that the results may profitably feed into the W3C activity on XML schemas. According to Jon Bosak (XML WG Chair), design work by the XML WG on XML schemas using instance syntax is likely to be re-chartered. Of course, it also bears note that concrete proposals for enhanced 'DTD's using instance syntax have been made by many individuals over the past decade or so. See, for example, references in chapter 8 of The SGML FAQ Book: Understanding the Foundation of HTML and XML by Steve DeRose: "SGML: It's 3, 3, 3 Languages in One."

"SABLE is an XML/SGML-based markup scheme for text-to-speech synthesis, developed to address the need for a common TTS control paradigm. The SABLE specification evolved as an initiative to combine three existing speech synthesis markup languages: 1) SSML, the Speech Synthesis Markup Language; 2) STML, the Spoken Text Markup Language; 3) JSML, the Java Synthesis Markup Language. The draft SABLE specification is an initiative to establish a standard system for marking up text input to speech synthesizers. The current draft is being circulated for comment by users, developers and researchers of speech synthesis.

Together with Guillaume Belrose, W3C's Dave Raggett (on assignment from HP Labs) "is developing a voice browser to test out ideas for using context free grammars for more flexible voice interaction dialogs. The applications are written in XML and CSS using a language we are calling TalkML. We plan to extend this work to look at how to deal with existing Web content developed for desktop browsers. Some ideas for this are covered in a W3C NOTE ['Voice Browsers'] I wrote last year with Microsoft's Or Ben-Natan. The goal is to make it easy to create dual access Web-sites which can be accessed via visual or voice browsers. See also my talk on Style sheets for Voice Browsers, as presented at the Developer's Day at WWW8.
"TalkML is an experimental XML language for voice browsers, and is being developed by HP Labs for use in the following markets: (1) Call centers (IVR++) -- sales and support services accessed via 800 numbers, adding speech recognition to today's DTMF (touch tone) systems; (2) Smart phones with displays; (3) Access to email, appointments, news and travel services etc. while your are on the road (in-car systems); (4) Mobile devices too small for decent displays or keyboards, WCDMA palmtop organizers/pagers with low enough cost to be a must-have (like cell-phones). Guillaume Belrose helped to devise TalkML and develop the sofware."

A NIST project cordinated through MEL (The Manufacturing Engineering Laboratory) at the National Institute of Standards and Technology, under Project Leader Joshua Lubell. The objective of this NIST-sponsored project is to "explore the use of XML (eXtensible Markup Language), a standard for structured document interchange on the Web, for exchanging complex data objects between tasks in a distributed workflow application." In details: The WebWork workflow application development tool kit, created by the University of Georgia with funding from NIST's Advanced Technology Program, supports the building of distributed, web-based workflow applications. NIST has demonstrated the benefits of XML for representing highly structured documents such as product data standard specifications and has shown that WebWork can be integrated with an XML repository. Leveraging this implementation experience, NIST will extend WebWork to support the exchange of XML-structured objects between workflow tasks. NIST will demonstrate the efficacy of this approach by building a small application to manage a subset of the workflow in ISO TC184/SC4 (International Organization for Standardization Technical Committee 184, Subcommittee 4), an international standards body developing specifications for the representation and exchange of industrial data for which NIST serves as Secretariat."
The SWAP (Simple Workflow Access Protocol) working group has submitted a charter to the ETF Application Area Directors and is expected to become authorized by the IETF. SWAP is "a protocol designed to allow for interoperability between workflow systems and between workflow systems and other applications. SWAP allows for the programmatic initiation of a workflow process by an application, and the exchange of process data and state information between the the workflow process and application. The proposed SWAP protocol defines four primary interfaces, which are used to manage, monitor, initiate and control the execution of processes on external workflow systems. . . SWAP is not intended to overlap with the WebDAV in any way. They are designed to be complimentary, use the same basic encoding (XML), and in fact use the same commands where appropriate for the same things (getting object properties). The goals of the two specs are different. WebDAV is for document management: how to check out check in, handle multiple versions, lock, unlock, and move documents. There is nothing in WebDAV about applications. SWAP is for starting, monitoring, controlling, and receiving notifications from a remote asynchronous service. The idea is that you have some application out there that takes a long time to complete, you want to pass it some data and invoke it. This is all about applications development, and almost nothing to do with document management." [adapted from the FAQ and main Web page, by Keith Swenson]

Theological Markup Language (ThML) is described in a separate document.
VSI (V-Systems Inc.), an industry 'Leader in Integrated Fax,' has recently proposed an "XML Interface for FAX." XML-F ('XML for FAX'), under VSI's new proposal, would be used for for connecting fax servers to applications, other fax servers, and fax service providers. "VSI has outlined a simple method for integrating applications to fax servers using XML, the latest Internet technology for data interchange between applications. Launched at a time when both network fax and XML are coming into the mainstream, VSI believes that their proposal, called 'XML-F', has the potential to solve a major issue facing the fax service community." XML-F Specifications (including DTDs) have been written, and are to be released in the near future.
"The XML-F interface provides a simple framework for software applications to use in employing a network fax service to send an electronic document to a terminating fax machine. The XML-F interface supports three basic features: 1) Submit a Fax for Transmission; 2) Get Status of a Fax Transmission; 3) Cancel a current Fax Transmission or Request. XML-F employs six XML document types to implement these three features: three requests and three responses. Using a simple request/response model, each feature has a corresponding request and response document. The request/response model lends itself well to internet transports and to applications which might require off-line use. All data is formatted as text and binary data is encoded using Base64 encoding. XML-F can be coupled with internet transports such as TCP/IP and HTTP and security mechanisms such as SSL to provide secure transactions over public networks. XML-F does not imply or require any particular transport, however. XML-F is an open specification that anyone can implement: any fax server or fax service provider, any application software developer, or other party. It is recommended that any public implementation of a server representing this interface fully implement all of the interface, while client systems might opt to implement only those portions which are relevant to the application."

- [February 15, 1999] "Fax Integration Using XML Technology." By Dave Droman and Gila Jones [V-Systems, Inc.]. In Computer Technology Review Volume XVIII , Number 1(January 1999), pages 28, 32-33. "As it stands today, there is no standard means of communicating between (1) fax servers and the applications that need faxing services and (2) among various fax servers or fax service providers across a network, including the Internet. . . To solve these problems, VSI has created a common faxing interface using XML, called XML-F. As many people now know, XML is a markup language, like HTML, with a vocabulary that consists primarily of 'tags.' HTML was specifically designed for marking up documents to communicate how they should be formatted for display on the World Wide Web. The purpose of XML is far more open-ended, but in general it is a 'meta-language' intended to be used to define other standard markup languages (known as Document Type Definitions or DTDs) that can be used to allow different systems to exchange information in a standard, process-readable format. Businesses can define their own vocabulary of XML tags and rules that are embedded within the DTD inside the XML document or made publicly available to any program that wants to comply with the agreed-upon information exchange format. The use of XML-specific parsers eliminate the burden of parsing and validating XML interchange documents, reducing the work and support required to implement an application reading XML."

"The ATSC T3/S17 specialist group is in the process of defining the application programming interfaces for a Digital Television Application Software Environment (DASE) compliant receiver. As this process evolves, the elements, attributes, properties, and values of BHTML will solidify. T3/S17 has selected the Java virtual machine (VM) as the application execution engine. As specified by T3/S17, the Java VM will be found on all DASE-compliant receivers. Aninda DasGupta, the T3/S17 chairman, proposed [what] he called 'Broadcast HTML' [which] uses Internet technologies favored by many T3/S17 members: it is written in XML, scales back HTML elements and attributes, and integrates synchronization functionality as new elements, attributes, and style properties. BHTML is an XML compliant language based on a reduced set of HTML 3.2 elements and attributes. Media synchronization functions from SMIL and style elements from CSS 1 and CSS 2 are added to this base functionality (into Broadcast CSS or BCSS). Appendix C of the August 6, 1998 draft ("XML-Data Specifying BHTML using the XML-Data Syntax") represents 'a first pass at defining the BHTML elements and attributes using the XML-Data (XMLD) notation'."
"xHTML specifies a collection of document type definition (DTD) sets that can be combined to specify an xHTML-based platform. Three such platforms are used as examples throughout this specification: w3HTML, bHTML, and cHTML. xHTML is designed to meet the requirements of consumer electronic and computer manufacturers that wish to produce a broad range of products with various levels of Internet connectivity and product features. xHTML started with HTML 4.0 and HTML 3.2. These elements and attributes were converted to XML, in line with the stated goals of the W3C for future HTML. The XML-based markup language was partitioned into DTD sets that correlated with the needs of platform developers to differentiated based on internet connectivity, memory footprint, and power management. xHTML is written in XML, therefore element names are case-sensitive."

Excerpt: "The debate over how to bring data and Internet technologies to digital television will bubble up this week, as a key industry group reconvenes here to discuss a set of proposals that has come under fire. . . Where the ATVEF's technology is based on standard Internet specifications such as HTML 4.0, BHTML is written in the emerging Extensible Markup Language (XML), a new language for advanced Web applications. BHTML scales back HTML elements and attributes by using parts of HTML 3.2, while it integrates synchronization functionality.

The initiative will 'write an open specification to integrate and harmonize VRML, MPEG-4, and Broadcast HTML BHTML into a seamless stream,' said Rob Glidden, co-chairman of VRML 3-D Integrated Media Working Group and one of 12 founding members of AIC. BHTML, written in the emerging Extensible Markup Language (XML), is designed for tight integration with the Java framework. Pointing to longstanding integration efforts between VRML and XML, as well as between MPEG-4 and VRML, Glidden said, 'This is a natural extension of what we have been doing at each of the groups'."

[January 28, 2000] SAX 2/Java (beta). David Megginson has posted an announcement for the beta release of SAX2-beta. "SAX is the Simple API for XML, a very-widely implemented event-based interface for processing XML documents. The beta release of SAX2/Java is now available for download at http://www.megginson.com/SAX/SAX2/. Highlights of the release: (1) Namespace support; (2) Configurability and extensibility through features and properties; (3) A new interface and base class for SAX filters; (4) Adapters for using SAX1 parsers with SAX2 and vice-versa; (5) Way too much JavaDoc documentation; (6) Public domain (even less restrictive than Open Source)... SAX2 adds standard methods to query and set features and properties in an XMLReader. It is now possible to request an XML reader to validate (or not to validate) a document, or to internalize (or not to internalize) all names, using the getFeature, setFeature, getProperty, and setProperty methods. There is no fixed set of features or properties available for SAX2: implementors are free to define new features and properties as needed. All feature and property names are fully-qualified URIs (often URLs), such as "http://www.acme.com/features/foo"; as with Namespace URIs, people should always define feature and property names based on URIs that they control. All XML readers are required to recognize the "http://xml.org/sax/features/namespaces" and the "http://xml.org/sax/features/namespace-prefixes" features (see below), and to support a true value for the namespaces property and a false value for the namespace-prefixes property: these requirements ensure that all SAX2 XML readers can provide the minimal required Namespace support for higher-level specs such as RDF, XSL, XML Schemas, and XLink. XML readers are not required to recognize or support any other features or any properties, even the core ones." [...] WRT SAX version 1: "Of the core classes and interfaces, only Parser, AttributeList, DocumentHandler, and HandlerBase (which is really a helper anyway) are deprecated. All of the rest -- InputSource, Locator, EntityResolver, DTDHandler, ErrorHandler, SAXException, and SAXParseException -- are left untouched."
[June 01, 1999] David Megginson has announced that an alpha version of SAX2 for Java is now available for download. SAX2 is "an update to the widely-implemented SAX 1.0 interface for XML parsers. SAX2 consists of two parts: (1) a new, extensible mechanism for querying and setting features and properties in SAX parsers in a standard way; and (2) a set of recommended core feature and property names.

- SAX - Simple API for XML. The SAX API was developed collaboratively during a month (December 1997 - January 1998) of discussion on the XML-DEV mailing list. SAX "is a simple, common, event-based API for XML parsers written in object-oriented languages like Java, C++, or Perl5 (the reference implementation is in Java). SAX is similar in philosophy to JavaSoft's JDBC -- it allows you to write an application once, then plug in any XML parser that has a SAX driver, just as the JDBC allows you to plug in any SQL database that has a JDBC driver."

References for 'XML and Literate Programming' have been moved to a separate document under the title "SGML/XML and Literate Programming." This document provides a collection of references for literate programming techniques and style in the context of descriptive markup languages, e.g., SGML, XML, DSSSL, HyTime, etc. Numerous researchers have observed that the goals of information re-use and data normalization embraced by both literate programming and SGML-based markup languages provide the basis for using the two technologies together.

A press release of October 13, 1998 clarified Microsoft's plans for XML support in the MS Windows operating system and in Microsoft Internet Explorer 5. 'XML 1.0, XSL, XML DOM, and XML Namespaces'. Support features as announced include: "Direct viewing of XML; High-performance, validating XML engine; Extensible Style Language (XSL) support; XML Schemas; Server-side XML; XML document object model (DOM)."
Description of Microsoft's XML support is provided in a collection of references accessible from a separate document.
[December 17, 1998] Sun Microsystem's "Java Project X: Java Services for XML Technology" is the new name for the Java services formerly released as the "Sun XML Library." On December 01, 1998, this development project was renamed Java Project X, and moved to "Early Access 2" with API updates, some speedup, and minor bug fixes. Java Project X is the codename for a set of core XML-enabling services written completely in the Java programming language. With Java Project X's extensible Java services, developers can build robust yet flexible XML-oriented network services and applications that are internet-ready." This release requires JDK 1.1.6 or later or JDK 1.2, and approximately 3.5M bytes of disk space. Sun's Java services in this new release provide full XML processing capabilities, including a fast XML parser with optional validation, an in-memory object model tree that supports the W3C DOM Level 1 recommendation, and basic support for JavaBeans integration with XML. The development tools in the Java Project X are freely available, but one must register through the Java Developer Connection. The second early access release is addressed to Java developers who want access to Sun's fast and fully conformant core XML software for their development. The library supports an optional in-memory object model tree for manipulating and writing XML structured data. The library is 'core' in the sense that significant XML based applications can be written using only this functionality, and that it is intended that other XML software be layered on top of it. That is, it is a building block for developers." According to the Release Notes, the Java Project X library conforms fully with open standards: "1) the parsers conform to the W3C's XML 1.0 recommendation; 2) the parse tree supports the XML (core) part of W3C's DOM Level 1 recommendation; 3) in combination, the two also support the current W3C XML Namespaces proposed recommendation; 4) the parser supports the SAX 1.0 API; 5) the entity resolution used within the parser normally conforms to the IETF's RFC 2376 registration for XML-related MIME content types, [but] this can be overridden as required."
[September 25, 1998] On September 16, 1998, Sun Microsystems, Inc. released an 'Early Access 1' version of The Sun XML Library. As described by David Brownell at the Montréal XML Developers' Conference, the XML Library is "a highly modular XML library that has been developed by the Java Software Division of Sun. The XML library is written in the Java programming language and provides support for the latest version (July) of the W3C DOM APIs and for the SAX 1.0 API. The XML package includes fast validating and nonvalidating XML parsers, preliminary support for XML Beans, and examples, including an XML Validation Service." The September 16th version is the first early access release, "addressed to Java developers who want access to Sun's fast and fully conformant XML library core for their development of extensible, conformant XML-enabled services and applications. That library supports fast parsing of XML documents, including optional validation, and supports an optional in-memory object model tree for manipulating and writing XML structured data. In addition, the core functionality supports an implementation of the W3C DOM APIs and the XML Namespaces proposal. The library is 'core' in the sense that significant XML based applications can be written using only this functionality, and that it is intended that other XML software be layered on top of it. All classes are written exclusively in the Java[tm] language, and accordingly may be used with any JDK 1.1 conformant system, including JDK 1.2 conformant systems. Developers have expressed strong interest in seeing XML enabling technology emerge from Sun because of the key role Sun has played in developing the XML specification and in creating the Java platform. The Java technology's 'portable code' along with XML's 'portable data' are valuable complements in creating truly platform-independent applications. Through the early access release, developers have an unique opportunity to participate in defining and evolving the XML Library." [adapted from the XML Library 'README' and 'FAQ' documents]

- How fast is Sun's XML parser included in the core toolkit? "In Sun's testing using JDK 1.1.6, the validating parser (doing lots of error testing) was significantly faster than the majority of the non-validating parsers tested and was an order of magnitude faster than other validating parsers. Of course, Sun's non-validating parser is faster still."
- [December 08, 1998] "XML and Java Technology - An Interview with Dave Brownell. [Part One]" From java.sun.com ['The Source for Java Technology']. December, 1998. "XML, the eXtensible Markup Language, is the universal syntax for describing and structuring data independent from application logic. This past February, XML 1.0 became a Technical Recommendation of the World Wide Web Consortium (W3C). From this milestone, numerous applications of XML are popping up far and wide - and more often than not they're using Java technology. We asked David Brownell, designer of Sun's Java Project X, for some perspective." [Excerpt:] Q: "Is there some special, natural affinity between Java technology and XML?" A: "You bet. Java software is portable code ... XML is portable data. By themselves, neither of these technologies provides such a solution. To get portable data, you need to pick a representation that is usable in most programming languages ... like XML, which is structured text. To get portable behavior, you need a maintainable program standard that runs on most computer systems ... like Java language class files. Use Java and XML together, and you get both. . ."

Annotated Version of the XML specification, from XML co-editor Tim Bray. This resource presents the unaltered text of the XML specification in one pane (frame) of the display, augmented by graphically distinct note markers of five types: "(1) Historical or cultural commentary; some entertainment value; (2) Technical explanations, including amplifications, corrections, and answers to Frequently Asked Questions; (3) Advice on how to use this specification; (4) Examples to illustrate what the spec is saying; (5) Annotations that it's hard to find a category for." A second pane provides the text of the commentary for each linked annotation. The resource also features a linked list of "Terms Defined in XML 1.0", and links to relevant sections of the XML specification from a list of EBNF productions. The annotations (some 308) are accessible from their titles as well.

[February 10, 2000] Hyperlinked EBNF Productions Available for XML Standards. A recent posting from Dan Vint reports on a new Web site which contains all the EBNF productions, validation and well-formedness constraints for the following specifications: XML, Namespaces, XPath, XSLT, XPointer, XML Stylesheet PI, and XML Fragments. "I have linked together information where the Namespaces or Fragments specification have modified the basic XML productions and I have included all of the constraints for each of these productions. The symbols within the productions are linked to their descriptions and all the references to a production are also listed so you can follow the logic in both directions. The menu on the left side needs a little time to build, but once available you can get to any production in alphabetical order by the specification. Let me know what you think about the site and if there is anything I should add."

World Wide Web Consortium Working Draft 1-October-1998. "This document allows a stylesheet to be associated with an XML document by including one or more processing instructions with a target of xml-stylesheet in the document's prolog." Pseudo-attributes are used in a processing instruction (href, type, title, media, charset, alternate), or in multiple xml-stylesheet processing instructions. Examples:
<?xml-stylesheet href="mystyle.css" type="text/css"?>and
<?xml-stylesheet alternate="yes" href="mystyle.css" title="Medium" type="text/css"?>. [local archive copy]
XML Catalog proposal. By John Cowan. "This is a proposal for XML Catalogs, a system based on SGML/Open catalogs (Socats) for translating XML public identifiers to XML system identifiers, which are Uniform Resource Identifiers [URI]." Note (1999-04-06): 'XCatalog' is now called 'XML Catalog'.
[May 11, 1998] An earlier proposal [see preceding item] for a standard mechanism to associate a stylesheet with an XML document by means of an XML processing instruction is documented in a recent W3C NOTE, "Associating Stylesheets with XML Documents." The NOTE, authored by James Clark, has been submitted to the W3C at the request of the XML Working Group. The proposed syntax and semantics are analogous to the HTML
LINKelement used to identity stylesheets, as illustrated in the following example:
<LINK rel="stylesheet" href="mystyle.css" type="text/css">
<?xml:stylesheet href="mystyle.css" type="text/css"?>.
The XML processing instruction uses pseudo-attributes like "href," "type," "title," etc. The examples shown in the NOTE are for CSS client-side stylesheets. Document identifier: NOTE-xml-stylesheet-19980405, W3C Note 5 Apr 1998. [local archive copy]

[December 06, 1997] "Why I Demand Schemata: Element Type Hierarchies for Transparent Document Structure Definition." By Henry S. Thompson (Language Technology Group, University of Edinburgh). Draft date: October 15, 1997. Overview: "In this paper I describe the XML-Data schemata proposal, concentrating on the motivation for and nature of the provision of an element-type hierarchy, in which element types can inherit attribute declarations and positions in content models from ancestors in the hierarchy. I argue that this represents a major improvement over the use of parameter entities to structure and maintain DTDs." [local archive copy]

[December 13, 1997] Architecture processing in XML: at the WG4 meeting in Alexandria, Virginia (December 1997), WG4 N1957 was accepted as the proposed text of an amendment to ISO/IEC 10744:1997 (HyTime). As a subclause to Annex A.3 ("A.3.4.4 Architecture Use Declaration Processing Instruction"), the proposed architecture use declaration (arch) processing instruction would provide "an alternative form of architecture use declaration for use in environments where notations or data attributes are not supported." The amendment was sponsored by Charles F. Goldfarb, Steven R. Newcomb, W. Eliot Kimber, and Peter Newcomb. See the related posting by Eliot Kimber "Architectures, Schemas, and XML: Proposed Amendment to ISO/IEC 10744:1997," with followup by David Megginson. [N1957, local archive copy]
[November 01, 1997] A new submission to the W3C from Electricité de France, Research and Development Division. The "STTS2" submission for "Simple Tree Transformation Sheets 2" would in principle govern the transformation of well-formed XML documents in order to render them in a HTML browser. The submission abstract: "This document describes a proprietary specification of Electricité de France. It specifies the format of STTS2 transformation rules that can be applied to a HTML document (without CSS styles) in order to take advantage of the Cascading Style Sheets and remove deprecated HTML elements or attributes in favor of CSS. Even if the specification deals only with HTML, this kind of transformation, or an extension of this specification, can be easily applied on the fly to well-formed XML documents in order to render them in a HTML browser without any XML plug-in or internal knowledge. The grammar of this specification is mainly based on the CSS2 grammar and extends it in some ways."

DOCTYPE replacement using a Java FilterReader/FilterStream. From Simon St.Laurent. "DOCTYPEChanger and DOCTYPEChangerStream are Java classes that allow you to change the DOCTYPE declarations as a document is being read into an XML parser. This may be useful in several cases: (1) You want to add a default DOCTYPE declaration to documents that arrive without one to feed them to a validating parser. (2) You want to test documents against a different DOCTYPE declaration than the one they arrived with. (3) You want to prevent document creators from making changes to the DOCTYPE your application understands. These classes allow you to set a root element, public identifiers, system identifiers, and an internal subset independently, and also let you specify whether the DOCTYPE declaration should be changed if present..." ['It's not real sophisticated, but you might want to check out my DOCTYPEChanger, which lets you specify a DOCTYPE. It's a Java FilterReader (or FilterStream) which strips out the old DOCTYPE (if you insist) and puts in a new one. You can put it in front of an XML parser if you want, or just run documents through it.']
ElCel Technology XML Validator. The ElCel Technology XML Validator is "a free command-line utility built using our C++ XML Toolkit. As its name implies, this is a validating XML processor.

"xmltex implements a non validating parser for documents matching the W3C XML Namespaces Recommendation. The system may just be used to parse the file (expanding entity references and normalising namespace declarations) in which case it records a trace of the parse on the terminal. Normally however the information from the parse is used to trigger TeX typesetting code. Declarations (in TeX syntax) are provided as part of xmltex to associate TeX code with the start and end of each XML element, attributes, processing instructions, and with unicode character data."

Earlier StarOffice entry (1999): The Sun product is expected to support XML -- in light of a Webcast statement by Star Division's Marco Boerries to the effect that XML specifications created as part of the StarPortal initiative would be submitted to the W3C, and that the APIs would be submitted to ECMA. An article by Stephen Shankland in CNET News.com offers the same hint from an interview with Marco Boerries: "In line with the plan to become more open, Star Office file formats eventually will become XML, and the standard for interacting with it will become published openly and contributed to the ECMA standardization group." Possible hints of some SGML pedigree in a couple help files: one shows that the color of "SGML" can be changed for display purposes, and another shows that SGML is in the glossary. [credits kd] Note: As of 2000-07, OpenOffice.org is "the open source project through which Sun Microsystems is releasing the technology for the popular StarOffice productivity suite... a principal goal is the establishment of open, XML-based standards for office productivity file formats and language-independent bindings to component APIs."

Main entry for W3C Recommendation 'Namespaces in XML' (REC-xml-names-19990114) and its commentary: "Namespaces in XML"
"A Proposal for Namespaces in XML", by Henry S. Thompson. Language Technology Group, HCRC, Edinburgh. May 27, 1997. Overview: ". . .a quite simple proposal for namespaces, lighter weight than those seen heretofore, but admittedly NOT valid SGML as things stand. I think its light weight, flexibility and functionality commend it." See also a "free-form XML" version submitted to the W3C SGML WG list. [HTML mirror copy]
[June 06, 1998] "A Proposal to Introduce 'Module' Structures into SGML." By Toru Takahashi. ISO/IEC JTC1/WG4 N1987. 98-05-15. Supersedes WG8 N1873. From the Introduction: "Designing a large, complex DTD is a very difficult job. One reason of this difficulty comes from SGML's restriction on namespaces. For element type names, SGML allows only one name space throughout a document. This restriction means, that if you intend to design a new DTD, you have to be familiar with all the element types you wish to use to construct the DTD, and have to select their names very carefully to avoid name conflicts. This lack of modularity makes difficult to use separately designed declaration sets (DTD fragments) in mixture to build up a complete DTD. For example, if you want to use pre-defined declaration sets for 'tables' and 'math expressions' together to construct your own 'report' DTD, you have to examine whether there are any name conflicts between them or not. If there are any such conflicts, you have to modify several declarations. This restriction in name space makes impossible to treat these declaration sets as public (read only) texts. Similar problems may occur on the parameter entity names. To solve these problems, I propose to introduce the concept of 'Module' into SGML. [local archive copy]

"Web Architecture: Extensible Languages." W3C Note 10 Feb 1998. NOTE-webarch-extlang. By Tim Berners-Lee and Dan Connolly (W3C). "This document is meant to be a fairly explanatory synthesis of the requirements for namespace extension in languages on the web, and in particular for the general language planned to be the common basis of many future applications, XML.

"xml-bind - XLinks from Types and Names." By Rick Jelliffe. Reference: Note 13 March, 1998 (Note-xml-bind-19980313). "This document is a NOTE for discussion by the W3C XML-related groups. It is primarily an alternative to the namespace proposal and a contribution to defining XLink requirements. RDF and XML-data designers may also find it relevant. [Abstract:] Current linking systems are based on links from elements (i.e., instances of element types in a document). This paper holds that several of the technologies under development by the W3C working groups are better characterized as links from types and names. Suggestions are made for a general architecture to handle this, and for how this can be integrated into XLink. Namespaces, parts of RDF, and SGML Open Catalogs are re-characterized as XLinks from types and names." [local archive copy]
"A Cut and Paste Infrastructure for XML." By Rick Jelliffe. Reference: Note-xml-cnp-19980131, Note 1-February-1998. "This document is a NOTE for discussion by the W3C XML-related groups. It is a personal critique of XML 1.0 PR, especially in the light of the namespace proposal, RDF and XML-data. It may be seen as a contribution to user requirements for an XML 1.1. XML Cut'n'Paste is a proposal for various conventions which address many sophisticated uses in Extensible Markup Language (XML) while retaining true to its underlying model, as an application of SGML."

"Comparison of SGML and XML." By James Clark. Reference identifiers: World Wide Web Consortium Note 15-December-1997, NOTE-sgml-xml-971215. The document provides a detailed comparison of SGML (ISO 8879) and XML under three section headings: 1) Differences Between XML and SGML; 2) Transforming SGML to XML; 3) SGML Declaration for XML, in two variants: (a) one which "takes advantage of the Extended Naming Rules Technical Corrigendum to ISO 8879, but does not make use of the Web SGML Adaptations Annex"; (b) one which "takes advantage of the Web SGML Adaptations Annex to ISO 8879". [local archive copy]
The new (informative) ISO 8879 Annex L: Added Requirements for XML "illustrates the relationship of SGML declarations to 'added requirements' by means of a real-world example, XML." The annex has a prose application summary and sample SGML declaration.
Some of the Recent Changes to ISO 8879 (Annex K, Web SGML Adaptations; also Annex L, Added Requirements for XML) are motivated by the goal of bringing SGML and XML into alignment. See Bob DuCharme, "SGML: Changing to Accommodate XML."
[July 19, 1998] "Converting an SGML DTD to XML." By Norman Walsh [ArborText]. Norm Walsh itemizes the steps in SGML-to-XML DTD conversion in a couple categories: "Many of these changes are straightforward and, for a large number of SGML DTDs, they will be fairly easy to accomplish. . . There are also some changes that may have a large impact on the semantics of the DTD. Luckily, these are mostly infrequently-used SGML features so they don't turn up often in most DTDs."

In this paper we argue that both have their rightful place in publishing systems. We discuss the impact of the new Web technologies on publishing systems by clarifying the relationship between XML and SGML. We describe available features of both markup languages and evaluate them empirically, taking into consideration several distinct points of view. Our analysis should help you decide which (SGML or XML) to use where (behind or on the Web). . . we argue that XML, devoid of SGML complexity, is ideally suited for the exchange and publication of documents/information on the Web. However, XML lacks some features which are very useful when creating behind-the-Web systems where reqirements stress the need for expressive information models and data-processing functionality..."

Using an XML Audit to Move SGML Data towards XML." By Charlie Halpern-Hamu, Incremental Development, Inc. Presented at XML'98 in Chicago. "This paper describes, at a technical level, how to assess the XML-readiness of your SGML data as a first step towards moving it towards XML. This paper suggests an 'XML audit': a technical review of current markup practice with eye towards simplification. The goal of an XML audit is to understand which portions of your current SGML application are not XML. The next step might be to start deemphasizing your use of those features. . ."

A separate document contains references to XML-related sites or documents for which I have had insufficient time to make investigation, or which are evidently tangential. Readers are invited to send email re: appropriate disposition. Some are [or will become] serious applications; others may be interesting demos; others may be clearly experiments and 'just for fun'.
