XMPP Specs

 

The base specifications of the Extensible Messaging and Presence Protocol (XMPP) formalize the core protocols developed within the Jabber open-source community in 1999. They were produced by the IETF's XMPP Working Group and published as RFCs in October, 2004.

Note: Only the ASCII version is normative!
