"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 case ACTION: Farrukh, write up ebXML registry UC ACTION: SimonR, advocate "3.6 Optional Match" in an eMail message

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

Testing

The test case document has been updated. http://www.ecs.soton.ac.uk/~swh/TestSketchCases/

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 space.

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: http://www.w3.org/2001/sw/DataAccess/DesignEvaluations

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 http://www.w3.org/2002/09/wbs/35463/initdn/

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 proposal.

AOB:

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.
