, an acronym for e
Xtensible
Messaging and
Presence
Protocol, is the generalized
XML streaming protocol that underlies
Jabber.

Systems that Support XMPP edit
XMPP-enabled clients include:
- ICQ
- Google Wave
- XMPP supports k
Transports edit
Transports are software libraries or applications that translate messages between otherwise-incompatible systems There are transports for the following systems:
- AOL Instant Messenger
- IRC
- MSN Messenger
and other instant messaging protocols.

Description edit
XMPP, the only
standardized IM protocoal, was created with the idea of implementing an extensive and complete system for exchanging messages and presense information. It is multilevel; IM-facilities themselves actually aren't even in the core of the XMPP spec.
there are a vast number of [
1] to XMPP which add support for such things like multi-user chat (think of "IRC 2.0"), which powers the
Tcl chatroom, file transfers, and even VoIP calls and video conferencing. Gateways to various legacy proprietary IM systems have been created as a measure to help converting people to XMPP and to alleviate for XMPP users the problem of contacting the proprietary IM networks. These gateways are not part of the XMPP specs; the only thing which is defined regarding this is the protocol for services that extend XMPP servers (that's how these gateways are implemented). Such gateways still suffer on a regular basis from changes made by the owners of the legacy IM networks to their IM protocols.
The set of protocols known as
Jabber was renamed to
XMPP after it was standardized by
IETF. The term "Jabber" is now often used to refer explicitly to this precursor of XMPP. Since some core XMPP facilities differ from that of Jabber in some respects, it's better to refer to this set of protocols as "XMPP".
Discussion edit
DKF: XMPP can also be used as a transport protocol for
SOAP, which is helpful for when you have long-lived webservice communications between two parties (especially when one party doesn't want to open incoming ports in their firewall).
I don't know if any Tcl SOAP package supports this transport protocol.
Historical edit
- jabbertcl (defunct)
- written by Kerem Hadimli, later maintained by Todd Bradley, was a Jabber Client Library (JabberLib (some relation to the other jabberlib?)) and a Tcl/Tk Jabber Client (zABBER).
