[DAIS-WG] DAIS-WG OGF27 Session Notes

[Steven Lynden]

DAIS-WG Session,  9.00am, Monday 12th October.
OGF27, Banff, Canada.

Total no. of Attendees: 11

Presenters: Isao Kojima, Steven Lynden

The session focused on reporting the progress made over the past six
months during which telcons have taken place regularly and work has
progressed on two fronts: interoperability testing of WS-DAIR
implementations and authoring of a WS-DAI-RDF(S) motivational/use case
document.  These efforts have lead to the submission of two documents:

WS-DAI RDF(S) Realization: Introduction, Motivational Use Cases and
Terminologies
WS-DAI and WS-DAIR Implementations - Experimental Document

Steven presented a report on the WS-DAIR interoperability testing and
experimental document. The attendees were urged to provide public
comments if possible. This presentation contained two sets of slides
on the OGSA-DAI and AMGA implementations. A brief summary of
recommended changes resulting from the interoperability testing was
presented. Isao asked what will the next step be. The answer was to
wait until the public comment period is finished and then discuss.

Questions from two attendees from KEK about AMGA and its support for
replication. These questions were answered but the attendees were
advised to read literature on AMGA for more details.

Most attendees arrived towards the end of the session (which was held
at 9am on the first day of OGF27 - one possible reason for the lack of
attendance at the beginning). Some attendees were new to DAIS, so the
spec introduction/structure slides were presented. Steven and Isao
gave a brief overview of the specifications and answered some
questions.

The availability of the motivational document was announced and Isao
made a brief overview of the document, especially the new use case
brought by the ADMIRE group. Unfortunately, the motivational doc was
not yet listed on the public comment page of OGF page but attendees
were shown where to get the document and urged to make comments.

In the Q&A session, people from NML-WG showed interest in the RDF spec
since they are also planning to use RDF. They are curious about how to
make heterogeneous data integration and/or data conversion between
RDF, XML and relational. Isao answered that it is out of scope of  the
current spec and Steven followed up by discussing how the specs
provide basic tools to support higher-level data integration
scenarios.
