<p><em>Note: This document has been retracted since its functionality is handled by &xep0163;.</em></p>
<p>A number of network services enable the exchange of information about an entity's availability for communications over the network. This information is usually called "presence". Examples include a person's availability to talk over a traditional or mobile telephony network, chat over an instant messaging (IM) network, or participate in a video conference. In this core sense, presence is a boolean, "on/off" indicator of network availability.</p>
<p>Over time, this core notion of presence has been extended to include other information about the entity that either (1) changes quickly or (2) affects the entity's interest in or ability to engage in communications. Examples of such "extended presence" include a person's proximity to or interaction with a user agent (e.g., "away" or "do not disturb"), activity (e.g., "driving"), ambient environment (e.g., "noisy"), and mood (e.g., "grumpy"). Related information includes data about the person's available devices (e.g., "phone" or "IM"), current contact modes or address, and date/time ranges for availability. Because extended presence information can change quite often (e.g., several times in the course of a typical IM session), it is distinct from more stable information about the individual (such as is captured in a vCard or other user profile).</p>
<p>This document describes a unified approach to the provision and communication of extended presence information using the Extensible Messaging and Presence Protocol (XMPP), in the form of a "protocol suite" that incorporates by reference a number of existing XMPP extensions.</p>
