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.
