Convene [1]RDF Data Access WG meeting of Tuesday, May 30, 2006 at kendall: I was not at XTech or WWW. What community interest was expressed? <kendall> AndyS: I'd like to hear about Jena community interest too LeeF: People seem to accept SPARQL as enabling the semweb get around the next corner <AndyS> Ack <AndyS> TBL said "SPARQL" in his intro, several times <kendall> Leigh Dodds gave a talk about SPARQL, including good stuff about protocol <kendall> EricP presented SPASQL EricP: Leigh Dodds' and Jim Melton's and ericP's SPARQL talks were well attended <kendall> 55 people at Jena user conference; lots of interest in SPARQL <kendall> Ingenta talk about SPARQL & Jena & VLDBs AndyS: Ingenta's talk at Jena User Conference and XTech came accross positively kendall: wondering if the JSON works needs more strength behind it tx <LeeF> +1 to what Andy said AndyS: it is in a good state for what most folks need AndyS: 80% of the folks [somewhere] claimed to know how to write SPARQL queries 2. XTech & WWW SPARQL/DAWG show reports LeeF: [describes the JSON callback issue] <AndyS> There is a proposal for a fix for this in JSONRequest so there is a coming solution for all <LeeF> I've heard much doubt expressed that JSONRequest a) solves the problem and b) will get enough steam to make momentum <AndyS> [15]http://www.json.org/JSONRequest.html <kendall> yep, I'm a bit skeptical about JSONRequest. <AndyS> maybe - but do we want to compete/promote a different solution which has not been security-reviewed? :-) <kendall> LeeF: can you drop a pointer to this Yahoo doc that describes the callback solution? LeeF: cross site scripting problem: page a gets access to intranet and gives data to another site. ... cross site scripting demo solution is to shut off browser security. ... [describes yahoo solution] ... problem: can't use POST ... proposal from Doug M-something, who invented JSON, has several security restrictions. <kendall> Douglas Crockford LeeF: in my talks, i don't see it gaining critical momentum <kendall> he didn't invent it as much as wrote it up :) <AndyS> Doug's slides: [16]http://json.org/json_www2006.ppt including lots of links to stuff of interest LeeF: Elias, AndyS and I discussed adding reference to the yahoo parameter-named-callback document ... I am not happy with any of these. <AndyS> Yahoo doc: [17]http://developer.yahoo.com/common/json.html kendall: agree, none are good ... odd to put in a results document LeeF: we may have crossed that line when we mentioned mime type <Zakim> kendall, you wanted to point out MIME type bug in JSON Results format doc kendall: i don't want to add the callback, but i want to fix the mimetype <scribe> ACTION: LeeF to fix mimetype in json-reults [recorded in [18]http://www.w3.org/2006/05/30-dawg-minutes.html#action01] LeeF: DaveB does not want to implement the the callback unless it's in the document kendall: i don't think we should explain how to get around security restrictions in a results format document JSON results format -- update on where we stand valueTesting -- update on where we stand <LeeF> yes <LeeF> I'm more comfortable saying nothing if we know that there's active work on the front going on elsewhere <kendall> EricP: Some browser vendors, including Mozilla, working on the x-site scripting issue, and there are some groups w/in the W3C who are also working on the issue <kendall> EricP: though some of them may be doing so somewhat informally <AndyS> Is this issue valueTesting as a whole or just the boolean case? <kendall> [19]http://www.w3.org/TR/XMLHttpRequest/ <kendall> FWIW test suite maintenance -- update on where we stand ACTION: AndyS: to draft of open-world = tests [recorded in [20]http://www.w3.org/2006/05/09-dawg-minutes#action07] [CONTINUED] <scribe> ACTION: EricP to propose text and tests to add {boolean < > = != boolean} to SPARQL [recorded in [21]http://www.w3.org/2006/05/09-dawg-minutes#action06] [CONTINUED] Renewed interest in SADDLE? kendall: some [22]traffic on and off list about saddle ... have folks done enough to work for us to consider doing DAWG work [23]extraction of the SADDLE input from the Boston F2F <kendall> AndyS: Issue isn't resolved; believes that we're not able to solve it w/ the resources & time we have left AndyS: I think it we couldn't do it in the time allotted <LeeF> +1 Andy and Eric - just not quite ready DDR Use Case? kendall: MWI, or someone, has a Device Description Repository ... historically used RDF to store the data. want to use SPARQL to query. ... semweb coordination group wants us to ... maybe use it as a use case? ... Anyone want to look at the DDR doc? <AndyS> The doc does not contain the string "RDF" - it's use cases kendall: ericP: I think we can slack on this. They will very likely look at SPARQL and tell us where it hurts <Souri2> Does SPARQL require that a graph pattern must contain at least one non-OPTIONAL triple-pattern? <kendall> PROPOSED: to meet on 6 June 2006 at 13:30 UTC Next meeting: 6 June, chair: KendallC, scribe: ??? <AndyS> Seconded <kendall> So RESOLVED? zakime, take up next agendum Souri's Q:s <LeeF> For that matter, you can have a WHERE { } Souri: SELECT ?a WHERE { } -- what's ?a ? <LeeF> zero rows <kendall> hmm, FWIW, there's an ISWC proposed paper that claims SPARQL is PSPACE-complete... I bid heavily to review it. :> <LeeF> or 1 row with an unbound var? <kendall> but someone here might be interested in following up w/ the authors? <LeeF> I would rather that these discussions be done on the WG lists. <EliasT> ericP, thanks for volunteering AndyS w/o his consent. <EliasT> It's ok to ask questions but to expect the WG to change/reconsider the document after the time has expired for comments, it causes disruption. <EliasT> However, if you have development questions, we have a public mailing list for development. <EliasT> [24]http://lists.w3.org/Archives/Public/public-sparql-dev/ <kendall> yes, elias, but these seem to be questions about the spec from a WG member. I don't see any requests for spec changes. <LeeF> 9:30 boston time <Souri2> Query => SELECT ?x WHERE {?x a _:y} <Souri2> Data => <John> a <Human> . <John> a <Mammal> . <John> a <Animal> . <Souri2> Result = {<John>, <John>, <John>} or just {<John>} ? <LeeF> Elias will do it. <EliasT> WHAT? <EliasT> WHAT? <EliasT> QUE? Next meeting: 6 June, chair: KendallC, scribe: EliasT <kendall> Elias to scribe next week ADJOUNRED <EliasT> Souri2, LeeF will answer that question for you. <EliasT> did Fred just leave? so it appears Query => SELECT DISTINCT ?x WHERE {?x a _:y} => {<John>} <Souri2> Query2: SELECT ?x WHERE {?x a ?y} <LeeF> sequence of solutions --> projection --> *set* of solutions (represented however an implementation chooses) --> maybe distinct Summary of Action Items [NEW] ACTION: EricP to propose text and tests to add {boolean < > = != boolean} to SPARQL [recorded in [25]http://www.w3.org/2006/05/09-dawg-minutes#action06] [NEW] ACTION: LeeF to fix mimetype in json-reults [recorded in [26]http://www.w3.org/2006/05/30-dawg-minutes.html#action01] [PENDING] ACTION: AndyS: to draft of open-world = tests [recorded in [27]http://www.w3.org/2006/05/09-dawg-minutes#action07] [End of minutes] _________________________________________________________________ Minutes formatted by David Booth's [28]scribe.perl version 1.127 ([29]CVS log) $Date: 2006/05/30 16:39:57 $ References 1. http://www.w3.org/ 2. http://www.w3.org/2006/05/30-dawg-irc 3. http://lists.w3.org/Archives/Public/public-rdf-dawg/2006AprJun/0099 4. http://www.w3.org/2006/05/30-dawg-minutes#agenda 5. http://www.w3.org/2006/05/30-dawg-minutes#item01 6. http://www.w3.org/2006/05/30-dawg-minutes#item02 7. http://www.w3.org/2006/05/30-dawg-minutes#item03 8. http://www.w3.org/2006/05/30-dawg-minutes#item04 9. http://www.w3.org/2006/05/30-dawg-minutes#item05 10. http://www.w3.org/2006/05/30-dawg-minutes#item06 11. http://www.w3.org/2006/05/30-dawg-minutes#item07 12. http://www.w3.org/2006/05/30-dawg-minutes#item08 13. http://www.w3.org/2006/05/30-dawg-minutes#ActionSummary 14. http://lists.w3.org/Archives/Public/public-rdf-dawg/2006AprJun/0083 15. http://www.json.org/JSONRequest.html 16. http://json.org/json_www2006.ppt 17. http://developer.yahoo.com/common/json.html 18. http://www.w3.org/2006/05/30-dawg-minutes.html#action01 19. http://www.w3.org/TR/XMLHttpRequest/ 20. http://www.w3.org/2006/05/09-dawg-minutes#action07 21. http://www.w3.org/2006/05/09-dawg-minutes#action06 22. http://lists.w3.org/Archives/Public/public-rdf-dawg/2006AprJun/0089 23. http://www.w3.org/2001/sw/DataAccess/proto-wd/saddle 24. http://lists.w3.org/Archives/Public/public-sparql-dev/ 25. http://www.w3.org/2006/05/09-dawg-minutes#action06 26. http://www.w3.org/2006/05/30-dawg-minutes.html#action01 27. http://www.w3.org/2006/05/09-dawg-minutes#action07 28. http://dev.w3.org/cvsweb/~checkout~/2002/scribe/scribedoc.htm 29. http://dev.w3.org/cvsweb/2002/scribe/ -- -eric home-office: +1.617.395.1213 (usually 900-2300 CET) cell: +81.90.6533.3882 (eric@w3.org) Feel free to forward this message to any list for any purpose other than email address distribution.
