1) UPDATES

Giovanni
 just returned from ISWC - International Semantic Web Conference. There 
were about 550 attendees. He presented a poster on how XRI adds the 
ability to do composite identifiers to provide provenance, solving a 
problem with RDF Named Graphs. 

His
 goal now is to try to write a full paper for the next conference to 
fully flesh out the idea and provide some examples of how it could work 
in practice.

Mike
 and Giovanni talked about how the OpenXDI project's code might be 
useful to attract the interest of the Linked Data community, since the 
community is growing and developing more interest in some of the types 
of problems that XDI solves. Mike and Giovanni will explore that 
offline.

Mike
 and Drummond said that there were two sessions on XDI at Internet 
Identity Workshop  Oct. 18-20 in Mountain View, both hosted by Mike (and
 neither of which Drummond was able to go to due to conflicts). The 
first one was more general itnroduction/demo, similar to the 
presentation Mike did at the Telco 2.0 conference in New York. 
Attendance was small but influential. The second one was specifically on
 XDI link contracts. This one attracted more attendees (8), including 
the gentleman who wrote the 800-63 specifications on identity assurance 
at NIST, and Craig Burton.

Mike
 also did a demo of OXGraph during the IIW demo fair, and there was a 
great deal of interest. Mike, Joseph, and Drummond all also had talks 
with Harry Halpin from the W3C. 

Drummond
 said that after IIW he had lunch with Victor Grey, a former member of 
the TC, who is working on private social networks and is very interested
 in using XDI as the protocol for connecting them.

2) OPENXDI UPDATE

Mike
 said that there is a new version of OxGraph that supports messaging. 
He's hoping to have it ready to test with real XDI accounts for TC 
members next week.

3) MESSAGE AUTHORIZATION

Mike
 explained that the OpenXDI work on messaging is raising so key 
questions about authorization, i.e., how to specify authentication 
information to support authorization of messages. For example, an XDI 
server asking, "Is it really =!2222 who sent that message?)

We spent some time reviewing and working on the "Messaging for access to non-public resource" section:

http://ox.gluu.org/doku.php?id=oauth:oxintegration&#xdi_messaging_for_access_to_non-public_resource

More work remains.

# MIKE and DRUMMOND to work on this over the next few days.

4) XDI DISCOVERY

Drummond
 talked with Mike at IIW about one obvious feature that we neglected in 
the XDI Discovery spec  proposal: resolution of cross-references to 
http: and https: URIs as  root nodes.

# DRUMMOND to add this to the XDI discovery page on the wiki.

5) NEXT CALL

The next call is next week at the regular time.
