This Working Group did not meet
NOTE: This charter is a snapshot of the 52nd IETF Meeting in Salt Lake City, Utah USA. It may now be out-of-date. Last Modified: 31-Jul-01
The working group will generate a set of standard track documents for the PRIM specifications. It will specify the protocols and data formats for the Presence and Instant Messaging services using a minimalist approach, complying with RFC 2779 and with CPIM, without adding implementation complexities. BCP 41 will be the basis for working group consideration of the transport implications of the PRIM designs with respect to network congestion
These protocols will take existing architecture and widely-deployed Presence and Instant Messaging services on the Internet as an intra- domain basis, and use CPIM over TCP for inter-domain exchange of presence information and instant messages.
The working group will work in collaboration with the IMPP WG to finish the CPIM specifications.
The PRIM specification documents will include the following:
o The inter-domain server-server protocol specification for the Presence/Instant Messaging services, which map the CPIM specification being developed by the IMPP working group over TCP. This specification defines protocols for subscription/notification and instant messaging.
o The client-server protocol specification for the Presence service. This specification defines a protocol to subscribe to a presence entity (presentity), to send a change notification to a watcher, and to control the presentity and presence information distribution.
o The client-server protocol specification for the Instant Messaging service. This specification defines a protocol to send and receive instant messages between a client and a server.
The PRIM proposal (draft-mazzoldi-prim-impp-01.txt) will serve as the starting point for the discussions in this WG.
