Introduction - General

• XCON Conference Framework complete as an XCON WG
  item
• Understandably discussions have primarily focused
  on voice/video conferences
• Framework introduces generic topics applicable to
  multiple signalling protocols and media types
• Conference Object
• Cloning Tree Model
• Text-based chat as an alternative media type
  provides a valid proof point for the XCON
  Framework
• Augments the work in SIMPLE WG
  draft-ietf-simple-chat
• Intent is to have no impact on existing IM
  protocols

Introduction - Chat

• Chat is a popular application and a good use case
  for an alternative conferencing media type
• IM Conferencing (Chat) has an important role to
  play in future XCON architectures
• In conjunction with other media (e.g. Voice,
  Video)
• Standalone (e.g. Chat Rooms)
• Existing chat systems have a broad range of
  features, from very simple to fairly complex
• Initial evaluation highlights need for some
  enhancements to data model to support chat

Document Issues/discussion

• How much more detail needs to be added to
  addressing additional chatroom functionality?
• Current version addresses the top-runners
  Nicknames, History, Logging, Alternate Venue
• If chatroom-analysis draft is not planned to be
  progressed, should we add more of the material as
  background to this document?
• However, once protocol details get added to this
  document, it could get quite large.

9
Way Forward

• Need WG feedback
• Update document based on feedback
• Editorial nits
• Clarification around scope per issues discussion
• Update details as the protocol document evolves
• Put in the queue for adding to XCON charter as
  other WG deliverables mature (e.g., protocol
  document).
