"3.6 Optional Match"
It must be possible to express a query that does not fail when some
specified part of the query fails to match. Any such triples matched by
this optional part, or variable bindings caused by this optional part,
can be returned in the results, if requested."
 -- http://www.w3.org/2001/sw/DataAccess/UseCases#r3.6

Discussion on whether this should be a *requirment* in the UC&R document.
RobS suggested it should be a Design Objective but did not convince the rest
of the working group.

ACTION: JimH, to work with Bijan to do some sort of UDDI/Web services use
ACTION: Farrukh, write up ebXML registry UC
ACTION: SimonR, advocate "3.6 Optional Match" in an eMail message

4. Streaming requirement

"3.12 Streaming Results
It must be possible, when returning multiple unordered results, for the
client to request that results be streamed. When the client requests
streaming results, all the data in one result must be available to the
client before all the data for the next result."
 -- http://www.w3.org/2001/sw/DataAccess/UseCases#r3.12

APPROVED: "3.12 Streaming Results" 
Abstention: Rob Shearer

5. Testing

The test case document has been updated.

The chair asked Steve Harris to catch test cases as they came up in the
email discussion.  At some time, the document should move into W3C CVS web

6. Design Evaluations and Poll

Dave Beckett has reviewed Algae2
Howard Katz has published XsRQL, an Xquery-style RDF query language.

ACTION: HowardK, Send own match of XqRQL to DAWG requirements
ACTION: AndyS, Write evaluation of XsRQL by 6 July.

Design evaluations summary:

ACTION: Kendall, Change link text to be something other than raw URLs.

Note the ongoing strawpoll in preparation of the July F2F so that there are
no unnecessary surprises for people at the meeting:

  Poll: RDF Data Access WG: initial design

Poll due to close (currently) on 5 July.

ACTION: DanC, split vote into query and protcool sections.
ACTION: DanC, remove "Asemantics variant of RDQL", changing RDQL to be one


Jim Handler asked about the process for managing comments to
public-rdf-dawg-comments.  Currently, it is the editors responsibility to
forward interesting emails to the working group mailing list.  Jim Handler
wondered if this was being responsive in showing we are listening.


Meeting closed: 15:29 UTC.
