Presence and Instant Messaging

Presence and Instant Messaging (PRIM) was an early proposal to the IETF of a standard protocol for instant messaging. The abstract model was first published as an IETF Request for Comments, RFC 2778 "A Model for Presence and Instant Messaging"[1] in February 2000, which was authored by Mark Day of SightPath (formerly of Lotus Software where helped develop IBM Lotus Sametime, now Chief Scientist at Riverbed Technology),[2] Jonathan Rosenberg of dynamicsoft (now the Chief Technology Officer and Vice President of Collaboration at Cisco Systems)[3] and Hiroyasu Sugano of Fujitsu Laboratories LtdLtd.[1]

No work has been done on it since 2001. Currently, SIP and its derivative SIMPLE (both of which Jonathan Rosenberg also co-authored or invented),[3] and XMPP are being considered for use as instant messaging protocols.
