The eXtensible Messaging and Presence Protocol (XMPP) is, at its most basic level, a protocol
for moving small, structured pieces of data between two places. From this humble basis, it has
been used to build large-scale instant messaging systems, Internet gaming platforms, search
engines, collaboration spaces, and voice and video conferencing systems. More unique appli-
cations appear every day, further demonstrating how versatile and powerful XMPP can be.

XMPP is made of a few small building blocks, and on top of these primitives many larger
constructions have been made. Within XMPP are systems for building publish-subscribe ser-
vices, multi-user chat, form retrieval and processing, service discovery, real-time data transfer,
privacy control, and remote procedure calls. Often, XMPP programmers create their own,
unique constructions that are fitted exactly for the problem at hand.

Most social media constructs that have propelled web sites like Facebook, MySpace, and
Twitter into the forefront are also baked into XMPP. Within XMPP, you’ll find rosters full of
contacts that create a social graph with directed or undirected edges. Presence notifications are
sent automatically when contacts come online and go offline, and private and public messages
are the bread and butter application of XMPP systems. Developers will sometimes choose
XMPP as the underlying technology layer simply because it gives them many social features
for free, leaving them to concentrate on the unique pieces of their application.

The possibilities are vast, but before you can begin, you need to know about XMPP’s different
pieces and how they fit together into a cohesive whole.
