                   Conference Information Data Model
                  for Centralized Conferencing (XCON)

Abstract

   RFC 5239 defines centralized conferencing (XCON) as an association of
   participants with a central focus.  The state of a conference is
   represented by a conference object.  This document defines an XML-
   based conference information data model to be used for conference
   objects.  A conference information data model is designed to convey
   information about the conference and about participation in the
   conference.  The conference information data model defined in this
   document constitutes an extension of the data format specified in the
   Session Initiation Protocol (SIP) event package for conference State.
