Can we proceed with just the model, serialization and messaging? Is the dictionary spec a must have?

thx,

1) UPDATES
We haven't had a call for three weeks, so we started with general updates.

- Markus has been busy at the European Peace Academy, and has been
talking to them about XDI and the federated social web. He has been
following our key developments, however, and plans to get more active once
his EPA term is done in 3 months.

- Bill has been talking to Neil, who is planning the upcoming Cloud
Symposium in London October 10-13 ,to reserve a space at the event for XDI.
Bill is proposing an XDI TC contribution to the forum, particularly if he is
able to get funding to go.

- Mike said that OpenLDAP is having LDAPCon in Heidelberg. He doesn't
think he'll be able to go, but wanted to point out that we are getting close
to being able to talk to the LDAP community about XDI.

- Drummond gave a brief update about Connect.Me, explaining that they
have launched a simple Twitter tagging application at tag.connect.me.

2) REVISED XDI GRAPH PATTERN DOCUMENT AND CORRESPONDING XDI STATEMENT
DOCUMENTS

Scott McGrath fixed the PDF uploads, so below are links to the latest
versions of The XDI Graph Model, XDI Graph Patterns, and XDI Statements for
XDI Graph Patterns.

Drummond would like to merge those into one document in advance of beginning
our work on the specs (see below).

3) OXGRAPH

http://openxdi.gluu.info/oxGraph/

Mike said that OpenXDI has implemented the basic operations, i.e., $get,
$add, $mod, $del. The most complicated is $del, because it can go through an
entire subgraph. $mod was the easiest since you can only update an XDI
literal.

The next focus is the server. Mike hopes to have the server out in about two
weeks.

Mike gave a demo of OxGraph, and how it worked with the different XDI
example graphs. After the server is ready, Mike would like to add support
for showing XDI operations in OxGraph.

Markus explained that in his set of XDI utilities, he had two text boxes,
one for the graph and one for the message being applied to the graph.

Bill asked about the status of dictionaries. Drummond said he has done work
on the basic patterns but that we need to document the core patterns just
like the others we have done. Bill suggested that in terms of content, we
should look at the several of the most-used RDF ontologies: FOAF and SIOC
(pronounced "shock").

4) SPEC DRAFTING

Mike asked about how close we are to formal drafting of 1.0 specs. Drummond
offered the opinion that we are pretty close, at least to the XDI Graph
Model and XDI Serialization specs, but that the key question is the resource
to draft the spec docs themselves. There was wide consensus that the current
TC membership is too busy with implementation and business activities to
take on major spec drafting activity at this time.

Bill feels that the spec must be as modular as we can make it.

With regards to how we might get more resources to draft the actual spec
documents, Drummond offered the view that the core TC members must be
involved. Mike said he might be able to get some help from Yuriy on the
OpenXDI project.

We discussed the current breakdown on the XdiOneSpec page:

http://wiki.oasis-open.org/xdi/XdiOneSpecs

We agreed that the two most important specs are XDI Messaging and XDI
Dictionary. Drummond pointed out that those two specs need the Graph Model
and Serialization.

# ALL fill in requirements for the first four specs on
http://wiki.oasis-open.org/xdi/XdiOneSpecs.

4) NEXT CALLS

The next call will be next week at the regular time. We also agreed that the
call two weeks from now will focus on XDI dictionaries, since we hope
Giovanni can attend that call.

------------
ONGOING ISSUES LIST

Each of these is a candidate for the agenda for future calls.

* TRANSACTIONAL INTEGRITY FOR XDI (added 2011-03-24)

Since versioning, as one example, involves multiple transactions that must
be commited as a group, we will need to address transactional integrity.
Specifically, we need to define how this will be handled at the protocol
level, vs. the implementation level.

* 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.

* COOL URIS
