1) XDI 1.0 SPEC DISCUSSION CONTINUED

The following wiki page was refactored per our discussion on last week's telecon:

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

Bill and Giovanni were not able to attend today, so the discussion was limited to talking about how much needs to be in the initial XDI Dictionary spec. Drummond shared the view that it only needed to be enough to support the other initial specs, particularly XDI Messaging.

We also discussed the practical need for an XDI Discovery spec, since early deployments need discovery. Thankfully that should be very easy since XDI discovery does not need to add very much on top of the other specs in the suite.

2) OPENXDI PROJECT UPDATE

We looked at the progress of the codebase and talked about XDI link contracts as the next key item that needs to be implemented.

Markus noted that the current code base is not yet doing XRI 3.0 parsing because it hasn't needed to yet, however this will be coming soon as it will be needed for XDI Discovery. He explainied to Mike the OpenXRI code components that provide XRI parsing, both 2.0 and 3.0.

3) AUTHENTICATION AND XDI LINK CONTRACTS

Mike suggested that link contract vocabulary needs to include machine-readable policy for the authentication requirement, since this is something OpenXDI needs to implement soon.

# MIKE to send his requirements in an email to the TC.

# DRUMMOND to suggest link contract vocabulary for authentication requirements.

4) 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.

* 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
