Hi:

I have submitted an Internet Draft that proposes to use Sigcomp together 
with a presence-specific static dictionary as a compression mechanism 
for presence. This tries to mitigate the problem of lengthy presence XML 
documents.

The I-D should include all the strings that we can get today in presence 
XML documents, although in this initial version of the draft I just went 
through the most relevant ones.

If you have any comments, please send them to the list and the author.

/Miguel

A New Internet-Draft is available from the on-line Internet-Drafts directories.

	Title		: The Presence-specific Dictionary for the Signaling Compression (Sigcomp) Framework
	Author(s)	: M. Garcia-Martin

The Session Initiation Protocol (SIP) [4] is a text-based protocol
for initiating and managing communication sessions.  The protocol is
extended by the SIP-events framework [5] to provide, e.g.,
subscriptions and notifications to presence information that are
carried in presence documents [8].  SIP can be compressed by using
Signaling Compression (SigComp) [2], which is enhanced by using the
SIP/SDP dictionary [7] to achieve better compression rates.  However,
the SIP/SDP dictionary [7] is not able to increase the compression
factor of (typically lengthy) presence documents.  This memo defines
the presence-specific static dictionary that SigComp may use in order
to achieve higher efficiency.  The dictionary is compression
algorithm independent.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
