Jabber
A streaming
XML technology mainly used for instant messaging.
"Jabber is best known as "the Linux of instant messaging" -- an open, secure, ad-free alternative to consumer IM services like AIM, ICQ, MSN, and Yahoo (see the IM quickstart). Under the hood, Jabber is a set of streaming XML protocols and technologies that enable any two entities on the Internet to exchange messages, presence, and other structured information in close to real time."
The most common misconception about Jabber is that it's solely for instant messaging—Jabber is more than a bridge to other IM systems or a set of protocols. Instant messaging is just one of countless ways that an
XML-based messaging technology such as Jabber's can be applied.
Jabber is an extensible client/server architecture that routes XML data between clients and services, which plug into Jabber servers as components.
