Entity management in XML applications

Control how your XML app discovers and accesses entities

Leigh Dodds is currently employed as an Engineering Manager at Ingenta. He has been developing applications on the Java platform since 1997, and has spent the last four years working with XML and related technologies. Leigh is also a contributing editor to xmlhack, and between February 2000 and June 2002, wrote the weekly "XML-Deviant" column for XML.com. He holds a Bachelors degree in biological Science, and a Masters in computing. As being the father of a lively 18 month old (Ethan) is a full-time job in itself, Leigh currently spends his copious amount of free time investigating how to improve the speed of manufacturing of Round Tuits, which he believes will revolutionize the parenting business.

Summary:  Entity management is the term used to describe the process for controlling how an XML application discovers and accesses external resources known as entities. Entity management is an often overlooked aspect of XML application development. However, the technique offers a number of advantages. This tutorial presents the basic principles of entity management through the concept of an XML catalog -- an address book that defines mappings from resources referenced in XML documents (such as a stylesheet or schema) to URI references (such as file system paths or URLs).
