next meeting???: 15 Mar???; scribe???

ACTION DanC: to consider adding 'privacy/security' issue, even if we're
most likely to just postpone it or mention it in passing in specs
CONTINUED


2. Requirements/Use Cases

ACTION Bijan: to propose text (story? etc.) to support WSDL requirement
CONTINUED

ACTION EricP: to review WSDL text proposal
CONTINUED


3. SPARQL protocol spec, Service Descriptions

Andy noted that construct can emulate "get the whole graph":
  CONSTRUCT {?s ?p ?o} WHERE GRAPH <g> {?s ?p ?o}
and that since WSDL modularizes the interface, large graph services
may choose not to offer getGraph

ACTION KendallC: discuss warnings in the protocol spec.
CONTINUED

ACTION KendallC: to refer to "get the whole graph" explanation from QL spec
DROPPED

ACTION KendallC: to add WSDL description of protocol to editor's draft, propose to WG:
CONTINUED

ACTION KendallC: to add "since we're using WSDL, you can use WS-Policy..." to protocol draft
CONTINUED


4. Service Descriptions
ACTION KendallC: to incorporate service description discussion notes in protocol spec
CONTINUED

ACTION Bijan: to work on "closeOver" work-alike with SteveH
DONE

5. SPARQL QL

AndyS, EricP, JJC, Don Chamberlin met to discuss xs:datatypes . Got positive
feedback from JJC, no scared faces from Don.

ACTION AndyS: to clarify 5.4 w/r/t closed world assumption
CONTINUED

ACTION AndyS: to explain how to get a whole graph with CONSTRUCT * and GRAPH.
CONTINUED

ACTION JosD: to review value testing section
DONE
http://lists.w3.org/Archives/Public/public-rdf-dawg/2005JanMar/0269.html

ACTION EricP: to propose to close valueTesting (bonus points for test cases, to EricP or others)
CONTINUED


6. issue: punctuationSyntax (turtle, N3, ...)
ACTION EricP: to propose results of N3 syntax discussion to DAWG
DONE
http://lists.w3.org/Archives/Public/public-rdf-dawg/2005JanMar/thread.html#227

There are multiple issues; whether we switch from existing syntax to
turtle+variables and whether we, AndyS freestanding list question,
whether FILTERs are in the graph pattern, some orthogonal issues about
what to call matches/regexps/etc. AndyS, EricP, and JosD all wanted
freestanding lists to be illegal.

Alberto noted that we've discussed syntax in previous f2fs, SQL-like
syntax was welcomed by developers, people are already implementing
SPARQL, changing again is not a good message. But sees
benifits to re-using turtle/n3 (parsers).

PROPOSED: adopt the turtle+variables syntax
http://lists.w3.org/Archives/Public/public-rdf-dawg/2005JanMar/thread.html#227
RESOLVED in favor
ABSTENTIONS: SteveH, AlbertoR

ACTION: SteveH to update the tests to reflect the new syntax

AndyS is working on a re-writer tool that may help SteveH.

ADJOURNED, remaining agenda:


7. test suite maintenance

ACTION SteveH: to to revise test manifest w.r.t. "background" and named graphs

ACTION DaveB: to to propose source test to approve

ACTION JosD: Jos to propose an optional test based on

ACTION op:dateTime triple

ACTION SteveH: to to propose tests for str() and =~

ACTION EricP: to pair with SteveH on making the HTML test results page

ACTION AndyS: to add the above graph test cases (analagous to valueTesting test cases)


8. SPARQL result set spec
ACTION DaveB: to consider use of xsi:dataType ala comment from Steer
