Book Description
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.

Book Description
“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.

Book Description
Replacing DTDs (Document Type Definitions) as the way in which XML documents are described and validated, XML schemas are essential for ensuring the accuracy and security of information in B2B transactions and other XML applications. This how-to guide employs extensive examples and source code to help developers and programmers get quickly up to speed on the practical application of this important technology. With in-depth explanations for each example, XML expert Mike Fitzgerald acquaints readers with coding structures, then moves to more advanced topics, including unique element and attribute values, keys, and how to use schemas with HTML. Like the other books in the series, this guide features comprehensive appendices listing all the datatypes and data facets, code indexes, and other time-saving features.

Book Description
This book describes the basics of W3C XML Schema (XSD) language, focusing primarily on 1.1 version of the XSD language. XSD 1.1 is a successor of XSD 1.0 language and provides advanced features for XML document validation. The book starts with describing basics of XML, and then describes the abstract model on which XSD schemas are based. It then progressively describes the various XSD language features that are used to write XSD schema documents ranging from the simple ones to much advanced XSD schemas. The book provides complete coverage of every aspect of XSD language, explaining the concepts supported by numerous examples. There are at least three reasons why standardizing such schemas is useful: 1. When two groups are preparing to exchange information using XML documents, a schema gives them a way to agree on what the structure of the documents is to be. 2. Because XML schemas are machine-processable and captured in a standard form, tools can be built to help build XML documents automatically, perhaps by extracting information from databases, or to automatically generate input forms to be presented to users. Similar tools can be used to automatically extract XML information into databases, program APIs, or spreadsheets. 3. When documents are generated or received through a network, validators can be used to check automatically that the rules have been followed. The W3C XML Schema language allows us to document the nesting structure of the elements and attributes in valid documents. It also standardizes types such as integer, decimal, or date that apply to the content of individual attributes or elements. About the Author Mukul Gandhi has been associated with work on XML and XML Schemas since many years. He was involved with the development of XML Schema 1.1 language, while W3C worked on standardizing the 1.1 version of XML Schema language. He has contributed to IBM's work on XML Schema 1.1 language standardization. He is also the member of Apache Xerces2 XML tools project that provides among other things conformant implementations of XSD 1.0 and 1.1 processors.
