Title : The Presence-Specific Static Dictionary for Signaling Compression (Sigcomp)
Author(s) : M. Garcia-Martin
Filename : draft-garcia-simple-presence-dictionary-06.txt
Pages : 25

The Session Initiation Protocol (SIP) is a text-based protocol for
initiating and managing communication sessions. The protocol is
extended by the SIP-events notification framework to provide
subscriptions and notifications of SIP events. One example of such
event notification mechanism is presence, which is expressed in XML
documents called presence documents. SIP can be compressed by using
Signaling Compression (SigComp), which is enhanced by using the SIP/
SDP dictionary to achieve better compression rates. However, the
SIP/SDP dictionary is not able to increase the compression factor of
(typically lengthy) presence documents. This memo defines the
presence-specific static dictionary that SigComp can use in order to
compress presence documents to achieve higher efficiency. The
dictionary is compression algorithm independent.

In the body type:

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.
