is xmpp an open standard, or a free standard?

JXSELF Are you doing personal on-line dating? Sorry, but your link, GOT ME READING the authors blog.

My research concluded: YES It is OPEN SOURCE and it is a sandard for the usage of that particular protocol!

Extensible Messaging and Presence Protocol (XMPP) is a communications protocol for message-oriented middleware based on XML (Extensible Markup Language).

The protocol was originally named Jabber and was developed by the Jabber open-source community in 1999 for near real-time, instant messaging (IM.

Unlike most instant messaging protocols, XMPP is defined in an open standard and uses an open systems approach of development and application, by which anyone may implement an XMPP service and interoperate with other organizations' implementations. Because XMPP is an open protocol, implementations can be developed using any software license; although many server, client, and library implementations are distributed as free and open-source software, numerous freeware and commercial software implementations also exist.

The Internet Engineering Task Force (IETF) formed an XMPP working group in 2002 to formalize the core protocols as an IETF instant messaging and presence technology.

The XMPP Working group produced four specifications (RFC 3920, RFC 3921, RFC 3922, RFC 3923), which were approved as Proposed Standards in 2004. In 2011, RFC 3920 and RFC 3921 were superseded by RFC 6120 and RFC 6121 respectively, with RFC 6122 specifying the XMPP address format.

In addition to these core protocols standardized at the IETF, the XMPP Standards Foundation (formerly the Jabber Software Foundation) is active in developing open XMPP extensions.

XMPP-based software is deployed widely across the Internet, and by 2003, was used by over ten million people worldwide, according to the XMPP Standards Foundation.

Thanks for the link Jason

So -- it's better to call xmpp a free specification? Because different people will infer different meanings from "standard"?

Thanks Jodiendo and lembas too

There are also Prosody (MIT) and ejabberd (GPL) which in my opinion are
not that greedy on resources and slow as most software written in Java.
Ejabberd is written in Erlang and Prosody is written in Lua.

That is a an assumption since I've never used Openfire. Ejabberd for
example can run on 512 MB (and probably less) virtual machine for low
traffic server with very few users registered directly on it.
