XML Schema Development

A 2-day hands-on course to understand and create XML Schemas

Overview

In XML-enabled applications, XML documents conform to an application-specific markup language. Schemas provide a means for defining the structure, content and semantics of markup languages, enabling you to validate against pre-defined specifications. XML Schema from the W3C supersedes DTDs (Document Type Definitions), which were originally defined in the XML1.0 Recommendation. XML Schema adds namespace support, extensive data typing functionality, and superior modularity. However, in keeping with similar developments in this area, the XML Schema language comes with a complex set of specifications. This two-day hands-on course is an essential guide to XML Schemas and designed to guide the delegate through the new specification and illustrate, through exercises, the process of XML Schema development, This course can also be delivered using XMLSpy as the Schema development tool.

Objectives

On completion of this course, delegates will be able to:

• Understand XML Schema specification
• Create XML Schemas
• Document your markup language so that other people understand its structure
• Validate documents in your markup language
• Author documents more easily with tools that understand schemas
• Supply type information to applications that use your documents
