Product DescriptionIf 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
Documentingschemas and extending XML Schema capabilities through annotations
In addition to the explanatory content, 'XML Schema'provides 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,'

Average Rating:
Rating: - exceptionally poorly constructed reference book
A real need for further editions on this book. As others have commented, it's very poorly constructed, poorly indexed and you'll be hard-pressed to quickly find accurate definitions. As other posters have suggested, O'Reilly should be worried that this one got published in this state.
Rating: - Semi-techie's evaluation
This book tells you what you need to know. However, it is a bit of a hard slog because it doesn't tell you why you need to know it. It also throws in obscure acronyms and not only expects you to know what they stand for, but what those protocols/standards/programs imply. Yes, you can learn all you need to know about SQL schema, (and more than you need to know - without telling you why you need to know it, you don't know what to skip), but it is a little more painful than it has to be.
Rating: - It is not easy to read it but there is not so much of other books
XML Schema is used almost everywhere (in connection with XML documents, Web Services, SOAP etc.). So I as other people needed to master XML Schema. There is not a great choice of XML Schema books. Specification is already quite getting old. The book is not easy to read. I read it sequentially chapter after chapter and I mastered a lot of basic rules. The main problem now I see is, XML Schema itself does not give you too much of design freedom. Sometimes you need to define a structure (data type) ... Read More
Rating: - Tough read
This book is very dry and terse. It has all of the required content but it doesn't provide much perspective of how it should be used. You could use it as a reference, but I recommend the XML Schema Companion before this one.
Rating: - An Editing Nightmare
This book had potential to be a definitive guide to XML schema. This is not the kind of book you can pick up and read cover to cover (unless insomnia is a real condition for you, in which case this book may help). It is, by no means, a tutorial of XML schema - or even a reference. It's more of an exploratory academic walk of the W3C recommendation and all of its foibles and nuances. There is wealth of information in this book, if you can glean it out from inbetween the droning prose and historical ... Read More
