Open federated chat protocol based on streaming XML (1999, Jabber → RFC 6120/6121/6122) — the first serious competitor to proprietary IM protocols.
JIDs look like user@server.tld/resource (email-like). Servers federate via server-to-server S2S. Extensions ("XEPs") define everything from MUC (group chat) and OMEMO (E2EE) to PubSub and file transfer.
Used as the backbone for Google Talk (2005–2014), Facebook Chat (2008–2015), Cisco Jabber, Salesforce Chatter. Today relevant mainly within open-source communities (Snikket, Prosody, Movim) and some industrial/IoT systems. Competitor: Matrix.
