             Centralized Conferencing Manipulation Protocol

Abstract

   The Centralized Conferencing Manipulation Protocol (CCMP) allows a
   Centralized Conferencing (XCON) system client to create, retrieve,
   change, and delete objects that describe a centralized conference.
   CCMP is a means to control basic and advanced conference features
   such as conference state and capabilities, participants, relative
   roles, and details.  CCMP is a stateless, XML-based, client server
   protocol that carries, in its request and response messages,
   conference information in the form of XML documents and fragments
   conforming to the centralized conferencing data model schema.
