License to Enhance Messaging Oriented Network Access for Diverse Endpoints BOF (lemonade) Thursday, November 21 at 0900-1130 ================================== CHAIRS: Eric Burger Glenn Parsons AGENDA: 5 min Agenda Bashing (Chairs) 5 min Review of LEMONADE charter & WG status (Chairs) 40 min Requirements (Kue) 10 min Media Size (Ari) 20 min Status Counters (Ari) 20 min SNAP (Ari/Noam?) 30 min IMAP Extensions (John/Eric/Greg) 20 min Discussion of relationships/liaisons Proposed Charter ================ Internet Unified Messaging brings together the body of work currently chartered in VPIM, IFAX, IMAPEXT, and other IETF working groups. It also relates with the work of other bodies dealing with messaging services, such as wireless SMS, MMS, etc. The goal is to provide, over the Internet, a single infrastructure, mailbox, and set of interfaces for a user to get, respond to, and manipulate all of his or her messages from a collection of clients with varying capabilities, no matter what the media or source is. Initial work, in the VPIM and FAX WG for example, focused on the server and network interactions and has resulted in a rich base of Internet Mail standards to support unified messaging. Now that this work is stable in the industry, and with the proliferation of smaller and often mobile Internet devices, the issues of client access to Internet Mail need to be addressed. Given the potentially broad scope of "unified messaging", this BOF will focus specifically on the following work items: 1. Enhance message retrieval protocols to satisfy the requirements for low-latency playback of multimedia content. 2. Extend and/or profile message submission and retrieval to satisfy the requirements for low-bit-rate or high-latency transports and limited-processing devices, such as mobile endpoints. 3. Create appropriate message notification protocols to satisfy the need for reporting the status of different message contexts. 4. Extend message retrieval protocols to efficiently support limited-capability devices by offering data transformation services and other appropriate server processing. 5. Extend and/or profile Internet mail services (such as SMTP) for use in "unified messaging" environments. If it turns out that native Internet mail services can not be used in such environments, define, where appropriate, translation between Internet Mail and other messaging systems to share a common Internet mailbox service. The BOF is aware of several related activities in other groups: - 3GPP TSG T WG2 SWG3 Messaging - W3C Mulitmodal interaction Activity - Open Mobile Alliance - 3GPP2 TSG-P - 3GPP2 TSG-N The goal is to coordinate efforts with at least these groups as required. While there is obvious synergy, given the end-of-life of the VPIM and FAX work groups and the similar membership, the BOF does not expect to coordinate with those groups.
