Java document object model (JDOM)

(Context: Software)

Definition

A way to represent an XML document for easy and efficient reading, manipulation, and writing.

JDOM Introduction

While JDOM defines an API for Java, the name JDOM does not reflect the name Java, which is trademarked by Sun Microsystems.

JDOM is not an acronym and therefore also is not tied to the name DOM, which is the Document Object Model defined by the World Wide Web Consortium (W3C).

So what is JDOM?

JDOM was designed by Jason Hunter and Brett McLaughlin, with the help of James Duncan Davidson, as an open source API for XML document manipulation. Developers can use JDOM in their own products without having to release their products as open-source software. This licensing concept is similar to that of the Apache Web server. The only restriction is that developers adhere to all other standards terms of the license agreement. One advantage of its being open source, subscribers to the JDOM-interest mailing list contribute to JDOM's success by submitting bug fixes and upgrades to the API.

According to the JDOM Web site, JDOM was designed to behave like Java, using the Java Collections API. The goal was to make JDOM a natural API for Java developers, and provide a low-cost alternative for using XML.
