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.

1.  Introduction

   Presence and instant messaging are defined in RFC 2778 [5].  The

   Common Profiles for Presence (CPP) [2] and Instant Messaging (CPIM)

   [1] define two Universal Resource Identifier (URI) schemes: 'im' for

   INSTANT INBOXes and 'pres' for PRESENTITIES.  This document provides

   rules for locating the resources associated with URIs that employ

   these schemes via the Domain Name Service (DNS) [4].  These rules

   could no doubt be applied to the resolution of other URI schemes that

   are unrelated to instant messaging and presence.

   CPIM and CPP both specify oper...
