If you need to create or use formal descriptions of XML vocabularies, the W3C's XML Schema offers a powerful set of tools for defining acceptable document structures and content. An alternative to DTDs as the way to describe and validate data in an XML environment, XML Schema enables developers to create precise descriptions with a richer set of datatypes?such as booleans, numbers, currencies, dates and times?that are essential for today?s applications.Schemas are powerful, but that power comes with substantial complexity. This concise book explains the ins and outs of XML Schema, including design choices, best practices, and limitations. Particularly valuable are discussions of how the type structures fit with existing database and object-oriented program contexts. With XML Schema, you can define acceptable content models and annotate those models with additional type information, making them more readily bound to programs and objects. Schemas combine the easy interchange of text-based XML with the more stringent requirements of data exchange, and make it easier to validate documents based on namespaces.You?ll find plenty of examples in this book that demonstrate the details necessary for precise vocabulary definitions. Topics include: Foundations of XML Schema syntax Flat, "russian-doll", and other schema approaches Working with simple and complex types in a variety of contexts The built-in datatypes provided by XML Schema Using facets to extend datatypes, including regular expression-based patterns Using keys and uniqueness rules to limit how and where information may appear Creating extensible schemas and managing extensibility Documenting schemas and extending XML Schema capabilities through annotations In addition to the explanatory content, XML Schemaprovides a complete reference to all parts of both the XML Schema Structures and XML Schema Datatypes specifications, as well as a glossary. Appendices explore the relationships between XML Schema and other tools for describing document structures, including DTDs, RELAX NG, and Schematron, as well as work in progress at the W3C to more tightly integrate XML Schema with existing specifications.No matter how you intend to use XML Schema - for data structures or document structures, for standalone documents or part of SOAP transactions, for documentation, validation, or data binding ? all the foundations you need are outlined in XML Schema.
“XML Schema 1.1 has gone from strong data typing to positively stalwart—so powerful it can enforce database level constraints and business rules, so your data transfer code won’t have to. This book covers the 1.1 changes—and more—in its 500 revisions to Priscilla Walmsley’s 10-year best-selling classic. It’s the guide you need to navigate XML Schema’s complexity—and master its power!” —Charles F. Goldfarb For Ten Years the World’s Favorite Guide to XML Schema—Now Extensively Revised for Version 1.1 and Today’s Best Practices! To leverage XML’s full power, organizations need shared vocabularies based on XML Schema. For a full decade, Definitive XML Schema has been the most practical, accessible, and usable guide to working with XML Schema. Now, author Priscilla Walmsley has thoroughly updated her classic to fully reflect XML Schema 1.1, and to present new best practices for designing successful schemas. Priscilla helped create XML Schema as a member of the W3C XML Schema Working Group, so she is well qualified to explain the W3C recommendation with insight and clarity. Her book teaches practical techniques for writing schemas to support any application, including many new use cases. You’ll discover how XML Schema 1.1 provides a rigorous, complete specification for modeling XML document structure, content, and datatypes; and walk through the many aspects of designing and applying schemas, including composition, instance validation, documentation, and namespaces. Then, building on the fundamentals, Priscilla introduces powerful advanced techniques ranging from type derivation to identity constraints. This edition’s extensive new coverage includes Many new design hints, tips, and tricks – plus a full chapter on creating an enterprise strategy for schema development and maintenance Design considerations in creating schemas for relational and object-oriented models, narrative content, and Web services An all-new chapter on assertions Coverage of new 1.1 features, including overrides, conditional type assignment, open content and more Modernized rules for naming and design Substantially updated coverage of extensibility, reuse, and versioning And much more If you’re an XML developer, architect, or content specialist, with this Second Edition you can join the tens of thousands who rely on Definitive XML Schema for practical insights, deeper understanding, and solutions that work.

As a result, it's already won over the allegiance of developers everywhere. If you need XML answers quick and on the fly, this compact book is most definitely the book for you.
"The book addresses a sorely missing set of considerations in the real world... This is a very timely book."-Peter Herzum, author of Business Component Factory and CEO of Herzum SoftwareXML is a tremendous enabler for platform agnostic data and metadata exchanges. However, there are no clear processes and techniques specifically focused on the engineering of XML structures to support reuse and integration simplicity, which are of particular importance in the age of application integration and Web services. This book describes the challenges of using XML in a manner that promotes simplification of integration, and a high degree of schema reuse. It also describes the syntactical capabilities of XML and XML Schemas, and the similarities (and in some cases limitations) of XML DTDs. This book presents combinations of architectural and design approaches to using XML as well as numerous syntactical and working examples.* Designed to be read three different ways: skim the margin notes for quick information, or use tables in the appendix to locate sections relevant the to a particular issue, or read cover-to-cover for the in-depth treatment. * Contains numerous tables that describe datatypes supported by the most common DBMSs and map to XML Schema supported data types.* Unique focus on the value added role and processes of the data architect as they apply to enterprise use of XML.
