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.
Protocol Quality
These documents were reviewed for the IESG by Jon Peterson. The PROTO
shepherd is Robert Sparks. Apps Area review of the XML-patch-ops document
was provided by Dave Crocker. Gen-ART review of XMLpatch-ops was provided
by Joel Halpern.
