"Conference Information Data Model for Centralized Conferencing (XCON)", Oscar Novo, Gonzalo Camarillo, David Morgan, Jari Urpalainen, 6-Apr-09. ( bytes)

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.

"Conference Event Package Data Format Extension for Centralized Conferencing (XCON)", Gonzalo Camarillo, Srivatsa Srinivasan, Roni Even, Jari Urpalainen, 3-Sep-08. ( bytes)

This document specifies the notification mechanism for XCON (centralized conferencing). This mechanism reuses the SIP (Session Initiation Protocol) event package for conference state. Additionally, the notification mechanism includes support for the XCON data model and for partial notifications.

"Centralized Conferencing Manipulation Protocol", Mary Barnes, Chris Boulton, Simon Romano, Henning Schulzrinne, 13-Jul-09. ( bytes)

The Centralized Conferencing Manipulation Protocol (CCMP) can create, retrieve, change and delete objects describing a centralized conference, such as state and capabilities of the conference, participants, and their roles. The conference information is contained in XML documents and fragments conforming to the centralized conferencing data model schema. CCMP is a state-less client-server protocol based on a request/response model. Conferencing clients send requests to conference servers, which respond to the client with the conference information.

"Centralized Conferencing Manipulation Protocol (CCMP) Call Flow Examples", Mary Barnes, Chris Boulton, Lorenzo Miniero, Roberta Presta, Simon Romano, 13-Jul-09. ( bytes)

This document provides detailed call flows for the scenarios documented in the Centralized Conferencing (XCON) Framework and the XCON Scenarios. The call flows document the use of the interface between a conference control client and a conference control server using the Centralized Conferencing Manipulation Protocol (CCMP). The objective is to provide a base reference for both protocol researchers and developers.
