Instant Messaging / Presence Protocol Requirements
Mark Day, Sonu Aggarwal, Gordon Mohr, Jean-Marc Vincent · 2000
Presence and Instant Messaging have recently emerged as a new medium of communications over the Internet.Presence is a means for finding, retrieving, and subscribing to changes in the presence information (e.g."online" or "offline") of other users.Instant messaging is a means for sending small, simple messages that are delivered immediately to online users.Applications of presence and instant messaging currently use independent, non-standard and non-interoperable protocols developed by various vendors.The goal of the Instant Messaging and Presence Protocol (IMPP) Working Group is to define a standard protocol so that independently developed applications of instant messaging and/or presence can interoperate across the Internet.This document defines a minimal set of requirements that IMPP must meet.
