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
