Please try to preface each of your comments with your name so the transcription into the minutes is easier.

1) GENERAL UPDATE & ANNOUNCEMENTS
We have not had a call for several weeks and there has been a great deal of activity, so we'll start with general updates.
2) NEED TO PUSH FORWARD WITH 1.0 SPECIFICATION DRAFTS
There is an increasing need for 1.0 Working Drafts. We will discuss the milestones we want to work towards.
3) JSON SERIALIZATION
We have not as a group had a chance to review the final JSON serialization proposal resulting from the work at Whistler.
http://wiki.oasis-open.org/xdi/JsonFormatThis is now very stable, and it forms the basis for other work on the "new view" of the graph and the metagraph predicates, so we should review it as a group and make sure it addresses the list of issues Bill had with earlier proposals (at the bottom of the page).
4) UML DIAGRAMS
Last month Drummond posted a document summarizing some insights coming out of the XDI Retreat in mid-August:
http://www.oasis-open.org/committees/download.php/39382/new-view-of-xdi-graph-model-v1.pdf
This subsequently led to comparison of UML diagrams for the "new view" and "old view". A page has been created for these (but the actual graphics won't be posted until sometime tomorrow morning).
http://wiki.oasis-open.org/xdi/UmlDiagrams5) SYMBOLIC METAGRAPH PREDICATES PROPOSAL
Based on the insights coming out of the JSON serialization format and the "new view", Drummond has posted a proposal for using symbolic metagraph predicates instead of $ words:
http://wiki.oasis-open.org/xdi/SymbolicMetagraphPredicates
6) OTHER TOPICS
If we have time (this is our ongoing issues list):
* Link contracts examples.
* Equivalence semantics: close on whether we need an additional $word that is the equivalent of Higgins Personal Data Model (PDM) semantics of h:correlation, which is not as strong as $is.
