RDF Data Access Working group (31 Oct 2006)

Short meeting: revised agenda:

• Track action items

• Next meeting

• Continued discussion about the SPARQL algebra

<kendallclark> speaking for UMD, I care vastly more about having the semantics look like they're starting to look *now* than I am about all the entailment stuff, which I still think we should just punt on.

<AndyS>{ patterns, filters, patterns OPTIONAL { P } } =>{ { group(join patterns, filters) } OPTIONAL { P } }

<ericP> minutes from 2 weeks ago

<LeeF> Another example: { P1 F1 OPTIONAL { P2} P3 F2 }

<kendallclark> I propose we approve those minutes.

<kendallclark> Someone 2nd?

<kendallclark> 2nd'd, LeeF

<AndyS>{ ( ( join P1 where F1 ) LeftJoin/OPTIONAL { P2 } ) join P3 where F2 }

<AndyS>Domain is done naturally by the algebra ; as are dups and union (Chilean cardinality) modulo BGP and the blank node mapping function

<LeeF> thanks

<SteveH> I could probably re-assume test stuff, though my time is a bit patchy

<LeeF> seconded!

<LeeF> ;-)
