Technical Summary
 
This document set provides a new capability for SIMPLE: partial
publications and notifications. Partial publications and notifications are
updates to previous transmitted presence documents which omit redundant
information, thereby saving bandwidth and processing. Both of these rely
on a common partial presence document format, 'application/pidf-diff+xml'.
These diffs are applied to existing presence documents through the
patching technique described in the xml-patch-ops document.
 
Working Group Summary
 
The working group supports the advancement of these specifications, and in
fact much protocol work inside and outside the IETF relies on this.
