EricP: it should just happen

<LeeF> The EBV of any literal whose type is xsd:boolean, xsd:string or numeric is false if the lexical form is not valid for that datatype (e.g. "abc"^^xsd:integer).

<LeeF> ACTION: ericP to try to produce a diff from CR to current editor's draft [DONE] [recorded in http://www.w3.org/2007/09/18-dawg-minutes.html#action14]

xml result format

<LeeF> http://lists.w3.org/Archives/Public/public-rdf-

<LeeF> dawg-comments/2005Jun/0028.html

<LeeF> -> http://lists.w3.org/Archives/Public/public-rdf-dawg-comments/2005Jun/0028.html original comment that prompted <link> element

LeeF: History of link element and summary of discussions with Alan

Alan proposes inline metadata to avoid server state.

scribe: comment is very late in process.
... would cost another cycle (at least one month).

LeeF asks for WG support ... none forthcoming.

<scribe> ACTION: LeeF: Reply to Alan's comment on metadata in SPARQL XML Results format [recorded in http://www.w3.org/2007/09/18-dawg-minutes.html#action15]

EricP: notes binding of, e.g. SOAP, has features.
... to support state

LeeF: status: waiting for W3C approval on process

<Zakim> ericP, you wanted to note a potential fix to [[• The EBV of any literal whose type is xsd:boolean, xsd:string or numeric is false if the lexical form is not valid for that

<LeeF> EBV text (only defined for strings, booleans, numerics)

<LeeF> "Effective boolean value arguments (labeled "xsd:boolean (EBV)" in the operator mapping table below), are coerced to xsd:boolean using the EBV rules in section 11.2.2 ."

protocol testing

Chair has feedback from implementers about existing HTTP bindings

scribe: Elias will have the protocol tests running

<LeeF> about SOAP versions

AndyS: Virtuoso have offered to back port to SOAP 1.1

mf:requires

<LeeF> beginning documentation of mf:requires

<SteveH> there's a lot of background noise here, sorry

Change to use mf:XsdDateOperation

mf: IllFormedLiterals -- actually used for tricky bits, not extension

<LeeF> mf:trickyBitOfSparql ?

<LeeF> mf:notewell ?

<iv_an_ru> mf:mayAccessAndReturnUnexpectedDataFromGraphsNotListedInManifest ? :)

<scribe> ACTION: AndyS: Invent and document an alternative to mf:requires for things that are noteable but not extensions in the test suite [recorded in http://www.w3.org/2007/09/18-dawg-minutes.html#action16]

<LeeF> mf:LangCaseInsensitivity can be struck

<LeeF> ACTION: LeeF to check and annotate open-eq-07 and -10 with mf:LangTagAwareness [recorded in http://www.w3.org/2007/09/18-dawg-minutes.html#action17]

<LeeF> strike mf:xsd-date-eq-xsd-dateTime

<scribe> ACTION: AndyS: Update vocabulary files and README for test [recorded in http://www.w3.org/2007/09/18-dawg-minutes.html#action18]

implementation report

<scribe> ACTION: AndyS: Update manifest for mf:requires [recorded in http://www.w3.org/2007/09/18-dawg-minutes.html#action19]

<LeeF> first draft of implementation report

LeeF: more results expected

<ericP> the SPARQL queries (and surrounding script) for generating the impl report

EricP: A test passes if ...
... no tests => green box

EricP: for any facet, there are certain tests associated with it

<LeeF> ACTION: ericP to answer "EBV of invalid numeric literals" email from Arjohn [DONE] [recorded in http://www.w3.org/2007/09/18-dawg-minutes.html#action20]

EricP: if two facets on a test, test processor calculates the best match as to which facet is the fail
... (e.g. already failed elsewhere for one facet => don't mark a failure for other facet)

LeeF suggests seeking wisdom in reporting coverage

Steve: can pass some facets without any implementation

<LeeF> No matter what, I intend to publish _all_ of the data we have

towards PR

exit criteria for CR

<LeeF> "A test suite gives reasonable coverage of the features of the query language."

<LeeF> "Each identified SPARQL feature has at least two implementations."

<LeeF> "Relevant media types are registered:"

<LeeF> "Normative dependencies have been advanced to Proposed Recommendation status:"

Our normative dependences are already at REC (Xquery, F&O)

Need to decide on "at risk" features: REDUCED, leading numbers in local part of prefixed names

<LeeF> also: what to do with syntax tests?

<LeeF> SteveH, do you implement REDUCED?

<SteveH> yes

<LeeF> thx

<iv_an_ru> I'm implementing REDUCED before Friday, BTW.

<LeeF> :-)

Leef: Does anyone want to propose removing REDUCED?

No such proposals made.

<SteveH> REDUCED is a big optimisation win for me in certain circumstances

<iv_an_ru> I've found REDUCED very useful for at least one optimization.

<LeeF> Great, good feedback to have.

<SteveH> but maybe if I had a streaming DISTINCT impl. it wouldn't be so useful

There is no "REDUCED" in the test suite.

<iv_an_ru> REDUCED is especially useful when there's a join between union that is faster when UNION and union that is faster when it's UNION ALL.

LeeF: Leading digits.

Several implemenations support it

LeeF: asks for proposals NOT to keep this feature. No such proposals.
... needs to get into interop report.

Eric: Min is 4 week in PR.

<LeeF> ACTION: LeeF to investigate PR mechanics, put together draft transition request [recorded in http://www.w3.org/2007/09/18-dawg-minutes.html#action21]

Ivan: Mitko has deployed a SOAP 1.1 endpoint

Souri: working to export RDF_MATCH to SPARQL query engine.
