The most complete and up-to-date guide to XMPP available, this practical book provides everything you need to know about this open network protocol for real-time communication. Devised for instant messaging, XMPP is now used for many diverse applications, including VoIP (Google Talk and Asterisk), social networking, information synchronization (TiVo), real-time collaboration, microblogging, and more.

XMPP: The Definitive Guide walks you through the thought processes and design decisions involved in building a complete XMPP-enabled application, and adding real-time interfaces to existing applications. You'll not only learn simple but powerful XMPP tools, but through real-world developer stories, you'll discover how common XMPP "building blocks" can help solve particular classes of problems. With this book, you will:

• Learn the basics of XMPP technologies, including architectural issues, addressing, and communication primitives
• Understand the terminology of XMPP, and learn about the wealth of XMPP servers, clients, and code libraries
• Become familiar with the XMPP concepts and services you need to solve common problems
• Construct a complete business application or real-time service with XMPP

More and more software developers and service providers are using XMPP for real-time applications. With the help of XMPP: The Definitive Guide, you can, too. This book is still in progress, but you can get going on this technology through our Rough Cuts edition, which lets you read the manuscript as it evolves, either online or via PDF.
