Chapter 2. Diving into the Core XMPP Concepts

While this book aims to get you to start building applications with XMPP quickly and effectively, it's important to understand some of the core concepts and how XMPP systems hang together. While attempting to keep things light, we'll run through these areas so that, when discussing or using XMPP, you'll understand all the terms being thrown around without having to run off to your search engine of choice.

In this chapter, we'll cover the following topics:

  • Identifying yourself on the network - the JID
  • The three communication blocks of XMPP
  • How extensibility is achieved
  • The life cycle of a connection
