Jabber Technology Basics is an excerpt from the O'Reilly & Associates book Programming Jabber: Extending XML Messaging, by D. J. Adams. In this chapter Adams describes the basic information needed to start building Jabber client/server/savvy applications.

The article introduces the Jabber Identifier (JID) assigned to entities Jabber needs to address, and what form the JID will take with common entities, for example servers or conference rooms. The JID is then broken down into its component parts for a discussion of how Jabber assigns priorities to route message traffic. Next XML message streams are thoroughly explained, including conversation namespaces. The article ends with a tutorial on the three XML fragment types in Jabber, the message, presence, and iq elements.
