A volume description and provisional Table of Contents for David Megginson's book Structuring XML Documents are provided below. See the full bibliography entry for a publisher's description of the work and other details; see also the "Prentice-Hall SGML Series" web page. David Megginson is the senior architect with Microstar Software Ltd., principal in Megginson Technologies Ltd.), and is the design lead for SAX, the Simple API for XML, a common event-based XML API now in use by many parsers and applications. Other published works by Megginson are listed on the author's Home Page. He may be contacted by email at email@example.com.
Structuring XML Documents is not a beginner's tutorial on XML, but a book written on an intermediate/advanced level, designed to help applications designers build XML/SGML DTDs that work in real-world document systems. The author interacts rigorously with five major industry-standard DTDs -- ISO 12083, DocBook, Text-Encoding Initiative (TEI), MIL-STD-38784 (CALS), Hypertext Markup Language (HTML 4.0) -- to illustrate how the necessary customizations and extensions can be implemented to support enterprise document processing objectives.
Structuring XML Documents is designed to help users apply XML and SGML to solve their document structuring problems. Specifically, readers will learn to: "1) analyze DTDs and adapt them for their specific processing needs; 2) build DTDs that are easier for others to learn, use, and process; 3) ensure structural compatability throughout their collection of enterprise DTDs; 4) use the new Architectural Forms standard to simplify complex DTD problems." [adapted from the back cover] The book's primary features, according to the front cover description: "1) Covers XML and Full SGML; 2) [Provides] the Expert's Guide to DTD Development; 3) [Helps] Leverage the Power of Architectural Forms; 4) Up to Date: Based on XML 1.0; 5) Companion CD-ROM Includes State-of-the-Art DTDs Plus XML Parsing Tools."
Structuring XML Documents is organized in four major parts:Part 1: Background, Part 2: Principles of DTD Analysis, Part 3: Advanced Issues in DTD Maintenance and Design, Part 4: DTD Design with Architectural Forms. Part 1 provides the reader with a review of XML/SGML DTD syntax sufficient to support an understanding of advanced topics treated in the remainder of the book; it also introduces the five industry DTDs that are to be used as models elsewhere in the book. Part 2 develops general principles for design and analysis using XML/SGML DTDs, as applicable to the collaborative work of writers, editors, and engineers. Part 3 of the book examines advanced topics in DTD design and maintenance, including: building compatibility between various versions of DTDs, document disassembly and reassembly, and DTD customization. Part 4, "DTD Design with Architectural Forms," illustrates the use of Architectural Forms and architecture processing relevant to SGML/XML documents, as recently standardized in the SGML Extended Facilities. The three chapters of Part 4 introduce Architectural Form processing, explain the most important features of the syntax, and address some advanced architectural-form constructs for difficult situations. In addition to a General Index (Appendix B), Appendix A of the book provides a detailed method for accessing the elements and attributes discussed in the industry DTDs: "Model DTDs: Index of Element Types and Attributes."
The companion CDROM for Structuring XML Documents provides several resources which enhance the value and usefulness of the book: 1) Free XML/SGML software and a live parsing demo; 2) HTML (live) links for the latest information on XML and SGML at the time of release; 3) Index of URLs mentioned in the book, organized by chapter; 4) Information on the five model DTDs used in the book, with links to local copies of four of them; 5) The standard ISO character entity sets for SGML.
The sub-series title of Structuring XML Documents -- "The Definitive XML Series from Charles F. Goldfarb" -- reflects the recent bifurcation of the primary Goldfarb series ("The Charles F. Goldfarb Series on Open Information Management"), at least for categorization, into "XML Titles" and "SGML Titles." In this schema, Megginson's book and The SGML Buyer's Guide are member of the former set, along with other XML titles "coming soon" from well-recognized authors: XML by Example, by Sean McGrath; The XML Handbook, by Charles Goldfarb and Paul Prescod; Designing XML Internet Applications, by Michael Leventhal, David Lewis and Matthew Fuchs; The XML and SGML Cookbook: Recipes for Structured Information, by Rick Jelliffe. The subseries description, as printed reads: "As XML is a subset of SGML, the Series List is categorized to show the degree to which a title applies to XML. 'XML Titles' are those that discuss XML explicitly and may alkso cover full SGML. 'SGML Titles' do not mention XML per se, but the principles covered may apply to XML."
