RE: [Simple] (Performance) Internal WG Review: Recharter of SIP forInstant Messaging and Presence Leveraging Extensions (simple)

["Drage, Keith \(Keith\)" <[e-mail]>]

If it updates RFC 3265 then the SIP WG needs to do it. There is a well
understood mechanism of providing requirements to the SIP WG to do this.
 
If it is an extension (i.e. extending RFC 3265 rather than updating it
with corrections), then RFC 3427 applies. In general this also means
that the SIP WG will do it, but if for example it is just a
uri-parameter or some such, then other groups could well do it. Again
there is a well understood mechanism of providing requirements to the
SIP WG to do this.

	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. A mechanism for initiating and managing Instant Message group
chat.
	
	5. 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.
	
	Any mechanisms created for managing Instant Message group chat
are
	intended to provide a bridge to the conferencing protocols that
will 
	be defined in XCON. They will be limited in scope to address
only 
	simple Instant Message chat with nicknames and will not attempt
	to address complex conferencing concepts such as sidebars. Their

	design must anticipate operating in conjunction with the
conferencing 
	protocols XCON is working towards.
	
	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.
