XML Schemaby Eric Van Der Vlist
Synopses & Reviews
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:
Primarily designed as a tutorial, this book also serves as a reference to many aspects of XML. It introduces and explains the main complexities of the XML Schema Recommendation and XML Schema creation and processing.
With both an introduction to creating schemas and a guide to the many complexities of the XML Schema Recommendation, this handbook is an on-the-fly learning aid for a tough subject.
