[May 31, 2002] Out-of-line XML (Ool). By Simon St.Laurent. "Ool is a set of filters which separate the textual content of XML documents (just the content in the elements, not the attributes) from the the markup. One set of filters converts an XML document into separate markup and text files, and the other filter recombines the two parts... XML pretty much thrives on embedded markup, with tags intermingled with content. While this has worked well, it's certainly not the only way and perhaps not the best way. Separating markup from text offers a different set of possibilities... As a bit of a bonus, there's also a SAX filter which abolishes mixed content through the handy expedient of wrapping the odd bits of text (those which have element siblings) in elements conveniently named "mix:ed". This may prove useful for constraining mixed content using DTDs and W3C XML Schema in ways which are not presently possible; RELAX NG needs no such assistance... Ool creates 'out-of-line' markup, which points into a separate file containing the text. Ool is a first step, and only a first step. Ool makes it possible to work with markup and text separately, but it's a very simple framework. You can do lots of funky tricks with Ool, especially on the recombination side, but fundamentally it's extremely simple, even brain-dead... Ted Nelson provided inspiration..."
[May 31, 2002] SAML 1.0 Specification Submitted for Approval as OASIS Standard. A posting from Joe Pato and Jeff Hodges (Co-Chairs of the OASIS Security Services Technical Committee) announces that the SAML 1.0 specification has been submitted for consideration as an OASIS standard. "The chairs are pleased to report that 10 companies have provided attestations of implementation and use for SAML 1.0. As SAML 1.0 conformance allows for modular implementation of the specification, the committee has determined that each aspect of the specification has been implemented by at least 5 companies. All implementers have been made aware of IPR claims regarding the specification and insofar as any processes have been established for complying with these claims, each implementer believes they have taken adequate steps to comply with any such rights, or claimed rights..."

[May 28, 2002] On-line Validation for RELAX NG. An online validation tool for RELAX NG helps users check RELAX NG schemas and instance documents without having to install any software locally. Notice for the interface was posted 2002-05-27 by MURATA Makoto. The 35+ examples are taken from the RELAX NG Tutorial. The tool was implemented using MSV, Xerces and Tomcat4. Note also the recent news item: "RELAX NG Published as ISO/IEC DIS 19757-2 (DSDL Part 2)."
[May 15, 2002] Fledgling Open Standards Organization. "Creating an alternative open standards organization..." is a new proposed endeavor floated on XML-DEV and led [2002-05-15] by Matthew Gertner. Initial goals [Gertner]: " Based on feedback, I would suggest the following goals, in order of priority: (1) Identify a core set of recommended XML specifications. (2) Identify or create subsets of certain specifications if the existing specs are needlessly complex (starting with XML itself). (3) Create new specs to fill in the gaps. To this I would add a metagoal: (4) Evangelize the recommended set of specifications or specification subsets to development organizations in order to promote adoption. Without "(4)," the whole effort is going to remain an academic exercise. Luckily, a lot of outspoken individuals have expressed interest. As next steps I would propose the following: (1) Set up a mailing list for discussion among interested parties. (2) Write a manifesto describing the organization's goals and raison d'etre. (3) Create a charter that describes the organization's structure, decision-making procedures, etc. I would use the Apache Group as the model for this, assuming this is appropriate (need to research this more). (4) Create a website..." See "New XML Group Creation" (newxmlgroup) at http://groups.yahoo.com/group/newxmlgroup/; "This is a group whose sole purpose is to put together a new XML-related organization whose purpose is something along the lines of "helping simplify the XML recommendations, standards, etc that's out there, as well as for new XML stuff that comes out in the future". The goal of the organization is definitely nebulous, but that's why this groups is here." Seairth Jacobs has "set up a mail group at newxmlgroup@yahoogroups.com (subscribe to newxmlgroup-subscribe@yahoogroups.com) where we can discuss the formation of this new organization, site, etc without being intertwined with unrelated topice. Once the organization and site have been set up, then an official mailing list (or whatever) will replace this one..."
[May 03, 2002] New 'May 31, 2002' Submission Deadline for PLAN-X Workshop on Programming Language Technologies for XML. The previous submission deadline of 'May 01, 2002' has been moved to Friday 31-May-2002. This workshop "aims to bring together researchers from the programming languages and XML communities, (1) to foster novel research to address unique challenges being posed by XML on current and future programming technologies; (2) to exchange information on early research experiences with XML-related programming systems, tools, and languages; and (3) to expose the PLI community to XML technologies and the potential impact of these technologies on future software." See the Workshop web site and news item 2002-04-02: "PLAN-X Workshop on Programming Language Technologies for XML.
[May 02, 2002] REST Architectural Style and TupleSpaces. In Alternative Web Services Architectures BOF," Sam Ruby writes: "The REST wiki suggests that the REST architectural style is most closely related to that of TupleSpaces. One important difference is that in TupleSpaces the sender does not identify the recipient. Data is addressed and routed based on content. Is there a place for such a model in 'Alternative Web Services Architectures'?..." See "Tuple Spaces and XML Spaces."
[May 02, 2002] OASIS Committee Specifications Approved by Member Vote as OASIS Standards. OASIS announced that the following have been approved by the OASIS membership as OASIS Standards: (1) Directory Services Markup Language (DSML) Version 2; (2) ebXML Registry Information Model (RIM) v2; (3) ebXML Registry Services (RS) v2. "The OASIS TC Process requires that at least 10% of OASIS organizational members vote in favour of the specification; for the balloting period 167 organizations were eligible to vote, so 17 votes were required." Karl Best congratulated and thanked "the OASIS Directory Service Markup Language TC, chaired by James Tauber and Winston Bumpus, and the OASIS ebXML Registry TC, chaired by Kathryn Breininger and previously chaired by Lisa Carnahan, for their effort in creating these new Standards." See the posting from Karl Best, OASIS Director of Technical Operations.
[May 02, 2002] XML Journals from University of Michigan Library "The University of Michigan Library's Scholarly Publishing Office (SPO) has just released online version of two significant University publications. Both journals have been encoded in TEI-based XML (level 2 for back issues with pages images, and level 4 for the more recent issues), and are made available through the DLXS suite of tools developed by the Digital Library Production Service at the University Library. The journals are fully searchable and are freely available. The Michigan Quarterly Review is the flagship scholarly and literary journal of the University of Michigan. The website includes all content published in the journal since its founding in 1962. Current and future issues will also be published online by SPO... Cross Currents: A Yearbook of Central European Culture first appeared in 1982 as a publication of the Slavic Department at the University of Michigan. The site includes page images and fully searchable text of all 12 issues of this publication..." Posting from Brian L. Rosenblum. See "Text Encoding Initiative (TEI) - XML for TEI Lite."
[May 02, 2002] Will UN/CEFACT Torpedo ebXML? The latest in a series of (politically possibly-correct) articles from Michael C. Rawlins is "Will UN/CEFACT Torpedo ebXML? And Mortally Wound Itself?" Excerpt: "UN/CEFACT, with OASIS, sponsored the ebXML initiative and is continuing development of the Business Process and Core Components work that ebXML began. The CEFACT Techniques and Methodologies Workgroup is responsible for maintaining the UN/CEFACT Unified Modeling Methodology (the UMM) that is the Bible for how CEFACT and other groups following the ebXML approach are supposed to develop eBusiness standards. TMWG will be meeting in late May. According to the e-mail, one of the topics set for discussion the troubling open issue of how the ebXML Core Components fit into the UMM. That's the setup... In the best case, everyone in CEFACT accepts TMWG's decision and rationale on their merits for dropping Core Components, and follows their lead. The current body of CC work, developed over 18 months by CEFACT's EDIFACT Working Group with assistance from ANSI ASC X12, is either picked over for what can be salvaged in compliance with the UMM, or discarded. Other standards bodies who have been basing their work on Core Components, such as the OASIS Universal Business Language Technical Committee, modify their approaches. OASIS modifies its ebXML related work to remove references to Core Components. Vendors, who have already built products to work with ebXML Core Components, modify their products. In the worst case, TMWG's action causes a severe rift in CEFACT. Many of the EDIFACT Working Group business experts, who have invested a lot of time and effort in Core Components development, leave..." See the 2002-05-03 response from Klaus-Dieter Naujok.
[May 02, 2002] ebXML Adoption Takes Off in Asia. "In the fifth ebXML Asia Committee Meeting, held from 18th - 19th April [2002] in Chinese Taipei, the representatives from Chinese Taipei, Hong Kong, Japan, Korea, Pakistan, Singapore, Sri Lanka (UNCTAD) and Thailand congregated to work on the measure for ebXML promotion and implementation in Asia. In the Meeting, the Committee, on the basis of review on the ebXML activities of each country and its work items, discussed measures to adopt ebXML and made several resolutions. Above all, participants agreed that ebXML implementation in real business was critical for the widespread adoption of ebXML. To promote ebXML implementation, the Committee decided to develop pan-Asia message design guideline by integrating the message design guideline prepared by KIEC with the ECOM's work on message assembly and core component definition. The Committee also decided to improve the ebXML registry linking model prepared by KIEC for the submission to OASIS ebXML Registry TC as a draft. During the Meeting, NII of Chinese Taipei and KIEC of Korea, which are operating ebXML registries, agreed to work on linking each other's ebXML registries to support eBusiness between Chinese Taipei and Korea. To promote participation of Asian experts and to facilitate the activities of ebXML Asia Committee members, the secretariat of ebXML Asia Committee will open an official ebXML Asia Committee website by the third quarter of 2002."
