PROPOSED: to accept

as a true record.

next meeting: Tuesday, October 26, 2004
  scribe volunteer, please?

propose to continue these 7 without discussion:

ACTION KendallC: expose our walking tour data to SPARQL querying clients
 ETA before F2F4
ACTION EricP: find logistics re F2F5 at tech plenary in Boston March
 28 Feb - 4 Mar (2 days).  Some WG preference to Mon/Tue of that week.
 some progress:
 http://lists.w3.org/Archives/Public/public-rdf-dawg/2004OctDec/0144.html
ACTION AlbertoR: owns issue 'DESCRIBE'
ACTION SteveH: own (i.e. propose resolution to) disjunction issue
ACTION SteveH: owns issue 'nested optionals'
ACTION DanC: owner of issue 'yes or no questions'
ACTION DaveB: Update the source section 9, add more formal links,
update the examples, try to think about extra constraints as EricP
proposed (SOURCE ?s and ?s only in in SELECT). Look at various
people's source test cases.


changes to the agenda?


2. Web Services Constraints and Capabilities

ACTION EricP: draft UC on overlap between RDF query and web service
constraints with respect to WS-Policy

Was this an action?
"DaveB requested a summary of the WS requirements (e.g. conjunction now,  
disjunction eventually), which Eric agreed to supply."


3. Feedback on the SPARQL design

ACTION Dirk: provide details about DB interfaces, re '?' and '$'
http://lists.w3.org/Archives/Public/public-rdf-dawg/2004OctDec/0160.html

ACTION: PatH review SPARQL def'ns post-publication

definitions for SELECT, projection, substitution [was: [Fwd: Re: ...]]

4. PREFIX syntax
cf http://www.w3.org/2001/sw/DataAccess/issues#prefixSyntax

ACTION: DaveB to illustrate prefix interaction details by example/test
http://lists.w3.org/Archives/Public/public-rdf-dawg/2004OctDec/0161.html
and following thread, including a proposal:

[[
1. Remove the second PrefixDecl term from the Query term, so there
is only one place prefixes are defined; before the ReportFormat term.

2. Change FromSelector to only allow URIs. Edit to be ::= QuotedURI
or alternatively, put it inside FromClause, delete FromSelector.

3. Define prefix/URI expansion to happen in the order they are given
in the syntax, with later prefixes overriding earlier ones.
]]


5. Toward adopting some tests

Is this test ready?
 http://www.w3.org/2001/sw/DataAccess/tests/#dawg-triple-pattern-001
i.e. every jot-and-tiddle of
 http://www.w3.org/2001/sw/DataAccess/tests/data/simple/data-01.n3
 http://www.w3.org/2001/sw/DataAccess/tests/data/simple/dawg-tp-01.rq
 http://www.w3.org/2001/sw/DataAccess/tests/data/simple/result-tp-01.n3

I don't see how the
    rs:size     "2" ;
is a consequence of the spec, for example.

Is this documentation sufficient?

p.s. sorry this is late; W3C AC meeting, TAG duties
got in the way of a timely agenda.
