[Simple] Please Comment: proposed SIMPLE charter

[Robert Sparks <[e-mail]>]

All -

Based on the feedback at and since IETF66, we've updated the proposed  
new charter
and milestones for the SIMPLE working group.

You'll find the result below (it's also at http://www.nostrum.com/ 
~rjsparks/charter.txt)

Please read this over and comment. If there is no objection or  
substantive comment
by the next two weeks (Aug 24), we'll ask Jon to start the process of  
making it official.

Thanks,

RjS

Description of Working Group:

This working group focuses on the application of the Session Initiation
Protocol (SIP, RFC 3261) to the suite of services collectively known  
as instant
messaging and presence (IMP). The IETF has committed to producing an
interoperable standard for these services compliant to the  
requirements for IM
outlined in RFC 2779 (including the security and privacy requirements  
there)
and in the Common Presence and Instant Messaging (CPIM) specification,
developed within the IMPP working group. As the most common services  
for which
SIP is used share quite a bit in common with IMP, the adaptation of  
SIP to IMP
seems a natural choice given the widespread support for (and relative  
maturity
of) the SIP standard.

This group has completed the majority of its primary goals and will  
focus
on the remaining tasks documented here and concluding. Any proposed new
work should be socialized with the chairs and AD early to determine if
this WG is an appropriate venue.

The primary remaining work of this group will be to complete:

1. The MSRP proposed standard mechanism for transporting sessions of  
messages
    initiated using the SIP, compliant to the requirments of RFC  
2779, CPIM
    and BCP 41.

2. The XCAP framework for representing and carrying configuration and  
policy
    information in SIMPLE systems.

3. A mechanism for representing partial changes (patches) to XML  
documents
    and extensions to the SIMPLE publication and notification  
mechanisms to
    convey these partial changes.

4. An annotated overview of the SIMPLE protocol definition documents.

Any SIP extensions proposed in the course of this development will,  
after a
last call process, be transferred to the SIP WG for consideration as  
formal SIP
extensions.

The working group will work within the framework for presence and IM  
described
in RFC 2778. The extensions it defines must also be compliant with  
the SIP
processes for extensions. The group cannot modify baseline SIP  
behavior or
define a new version of SIP for IM and presence. If the group  
determines that
any capabilities requiring an extension to SIP are needed, the group  
will seek
to define such extensions within the SIP working group, and then use  
them here.
