Abstract
The Presence Information Data Format (PIDF) defines a basic XML
format for presenting presence information for a presentity. The
Contact Information for the Presence Information Data format (CIPID)
is an extension that adds elements to PIDF that provide additional
contact information about a presentity and its contacts, including
references to address book entries and icons.

1. Introduction
Presence information facilitates communication; its usefulness can be
enhanced by providing basic information about a presentity or
contact. This specification describes a basic set of information
elements that allow a watcher to retrieve additional information
about a presentity or contact.
This specification defines extensions to the PIDF [9] Extensible
Markup Language [7][8][10] (XML) document format.
We describe elements for providing a "business card", references to
the homepage, map, representative sound, display name, and an icon.
This additional presence information can be used in PIDF [9]
documents, together with Rich Presence Information Data format [11]
(RPID), future-status [12], and other PIDF extensions.
All elements extend the <person> or, less commonly, <tuple> element
in the presence data model [13]. The <tuple> element is only
extended with Contact Information for the Presence Information Data
format (CIPID) elements if the information describes a service
referring to another person that is marked by an RPID <relationship>
element with a value other than 'self'. All elements described in
this document are optional.

RPID and CIPID both provide "rich" presence that goes beyond the
basic 'open' and 'closed' status information in PIDF. The presence
information described in these two documents can be supplied
independently, although in practice, both will often appear in the
same PIDF document. CIPID elements describe the more static aspects
of somebody's presence information, while RPID focuses on elements
that will likely change throughout the day. Thus, CIPID information
can often be statically configured by the user through the graphical
