    IETF

    This document describes an extension to vCard to support Instant Messaging (IM) and Presence Protocol (PP) applications. IM and PP are becoming increasingly common ways of communicating, and users want to save this contact information in their address books. It allows a URI that is associated with IM or PP to be specified inside a vCard.
