AGENDA
1) NEW DOCUMENTS: XDI GRAPH PATTERNS AND XDI GRAPH MODEL
As promised, Drummond has uploaded documents that illustrate the full set of basic patterns using the XDI graph model as explained in Giovanni's last document. The first is a set of visual graph diagrams showing the patterns for simple properties, complex properties, simple subjects, complex subjects, link contracts, and messages.

The second is an update to what used to be the XDI RDF Model document, now just titled the XDI Graph Model, that includes the metagraph symbol vocabulary:

DOC:
http://www.oasis-open.org/committees/download.php/41088/xdi-graph-model-2011-02-09.docThere is a ton of new documentation here, so we will need most of the call to review it together.
2) TINY BUT IMPORTANT REVISION TO THE JSON SERIALIZATION FORMAT
In doing the documentation above, Drummond realized that the metagraph symbol () should have been used instead of $ for serializing subcontexts in the JSON serialization format. Originally it looked like either $ or () could have been used, and $ seemed to make more sense. However as the semantics of the metagraph symbols are becoming more rigourously defined, it is now clear that () is not only semantically accurate but and solves one key semantic problem we would have had with using $. We'll discuss on the call to make sure there is consensus on this.
3) NEXT CALL
The next call is next week at the regular time.

ONGOING ISSUES LIST
Each of these is a candidate for the agenda for future calls.
* PROPOSED CONSTRUCTS/OPERATORS FOR XDI
Discuss the following wiki page originally posted by Giovanni:
http://wiki.oasis-open.org/xdi/XdiNewFoundation
* DICTIONARY STRUCTURE
Mike would like an example of the PDX dictionary as soon as we can do it.
* 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.
