Conference Information Data Model for Centralized Conferencing (XCON) Conference Information Data Model for Centralized Conferencing (XCON)
draft-ietf-xcon-common-data-model-13.txt draft-ietf-xcon-common-data-model-14.txt
Abstract
This document defines an Extensible Markup Language (XML)-based
conference information data model for centralized conferencing
(XCON). 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.
