Abstract
Presence and instant messaging are defined in RFC 2778. The Common
Profiles for Presence and Instant Messaging define two Universal
Resource Identifier (URI) schemes: 'im' for INSTANT INBOXes and
'pres' for PRESENTITIES. This document provides guidance for
locating the resources associated with URIs that employ these
schemes.
