KC: I think this is the corrected version <DanC_> [15]minutes 18 Apr [15] http://lists.w3.org/Archives/Public/public-rdf-dawg/2006AprJun/att-0052/18-dawg-minutes.html RESOLUTION: to approve minutes 18 Apr future meeting times KC: our scheduled time overlaps with RIF. it's not clear how much of an actual problem that is, but it's at least a potential problem. ... how about an hour earlier? <AndyS_> I'm happy to move -1 hour. DC: how about 9:30am Boston time, year round? [or at least over this summer] <AndyS_> (14:30 BST(GMTDT) , 13:30 GMT) hmm... 60, 90, or 120 minutes? weekly, every-other-week, or monthly? <AndyS_> CET is +1 hour to that. PatH: I lean toward frequent meetings and make them short if there's not much to do <SteveH> as long as the mail goes out I will rememebr to dial in PROPOSED: to meet Tuesdays 9:30am Boston time for 60 to 90 minutes, starting 16 May 2006 until further notice <SteveH> 2nd'd regrets ericp, afs for 16 May due to XTech RESOLUTION: to meet Tuesdays 9:30am Boston time for 60 to 90 minutes, starting 30 May 2006 until further notice EricP to scribe 30 May post-hoc action added by the scribe and former chair... <scribe> ACTION: EricP: to notify adminreq of the change in meeting time [recorded in [16]http://www.w3.org/2006/05/09-dawg-minutes.html#action01] JSON results format status EricP: I expect to get this done tomorrow. <scribe> ACTION: EricP to publish [17]http://www.w3.org/2001/sw/DataAccess/json-sparql/ [CONTINUES] [recorded in [18]http://www.w3.org/2006/05/09-dawg-minutes.html#action02] [17] http://www.w3.org/2001/sw/DataAccess/json-sparql/ punctuationSyntax: bnodes in predicates KC: I saw mail from Steve today DanC: looked for records re: disallowing bnodes in predicate position ... couldn't find any explicit decision to that effect ... As of 11 Nov, bnodes were in change was made in 1.629 2006/01/30 17:38:14 patH: may have last come up under rdfSemantics issue <Souri> [19]suggestion from Pat to take it out [19] http://lists.w3.org/Archives/Public/public-rdf-dawg/2006JanMar/0305.html hmm... we RESOLVED "that SPARQL QL editor's draft 1.623 section 2.5 addresses issue rdfSemantics and is sufficient to postpone issue owlDisjunction", and bnodes are out there. <kendall> SteveH: I remember discussion of this, colleagues suggest that the restriction is somewhat confusing <DanC_> I thnk I should edit the issues list to show that the 26 Jan decision re rdfSemantics also affects punctuationSyntax <kendall> DanC, I'd be happy for you to do that. SH: I'm getting feedback that prohibiting bnodes in Verb is inconvenient EricP: there's [something involving * that the scribe didn't really catch] AndyS: it would change the semantics... PatH: yes, it might work, but then it wouldn't work with OWL... ... but OWL might change in that direction too. SH: there are approved tests that are relevant AndyS: those tests don't test the semantics <scribe> ACTION: AndyS to find tests with bnodes in predicates and mark them as syntax errors (and unapproved until we approve them) [recorded in [20]http://www.w3.org/2006/05/09-dawg-minutes.html#action03] <scribe> ACTION: DanC to edit [21]http://www.w3.org/2001/sw/DataAccess/issues#punctuationSyntax to show ammendment 26 Jan [22]http://lists.w3.org/Archives/Public/public-rdf-dawg/2006JanMar/a tt-0298/26-dawg-minutes.html [recorded in [23]http://www.w3.org/2006/05/09-dawg-minutes.html#action04] [21] http://www.w3.org/2001/sw/DataAccess/issues#punctuationSyntax [22] http://lists.w3.org/Archives/Public/public-rdf-dawg/2006JanMar/att-0298/26-dawg-minutes.html KC: how do we re-sync editors drafts with published TRs? DC: well, you can ask to do an updated CR, or go back to WD, or ask for PR <DanC_> [24], Test/grammar question Geoff Chappell (Thursday, 6 April) [24] http://lists.w3.org/Archives/Public/public-rdf-dawg-comments/2006Apr/0002.html <DanC_> (I see Andy answered him, though we haven't done the [OK?] dance. dunno if we need to.) valueTesting <kendall> ACTION: Kendall to mark valueTesting as open on issues list (i.e., to really learn how to handle issues list) [recorded in [25]http://www.w3.org/2006/05/09-dawg-minutes.html#action05] EricP: no progress; pls continue. eta 2 weeks <scribe> ACTION: EricP to propose text and tests to add {boolean < > = != boolean} to SPARQL [CONTINUES] [recorded in [26]http://www.w3.org/2006/05/09-dawg-minutes.html#action06] test suite maintenance DC: my action went to Andy in the last meeting. <AndyS_> ACTION: AndyS: to draft of open-world = tests [CONTINUES] [recorded in [27]http://www.w3.org/2006/05/09-dawg-minutes.html#action07] <AndyS_> ACTION: AndyS to contribute a couple tests for computed-properties/virtual-prop/builtin. one using lists, and one not using lists [CONTINUES] [recorded in [28]http://www.w3.org/2006/05/09-dawg-minutes.html#action08] yes, DONE, ACTION: EricP and Jeen to fix OPTIONAL coding comments on RIF use cases KC: still interested?

(anybody have a pointer to a relevant message from the comments achive?) <Souri> Question: Isn't "I said \"Hello World\"" a valid plain literal? <AndyS_> [35]http://lists.w3.org/Archives/Public/public-rdf-dawg/2006JanMar/0 443.html [35] http://lists.w3.org/Archives/Public/public-rdf-dawg/2006JanMar/0443.html <AndyS_> #Is this comment\u0020 legal <ericP> # \u000d SELECT ...
