Have added descriptive sections (done). Structural markers in formal definition have pending work. Email from Axel and Birte. Progressing 14:10:29 Eric: not taking conservative path 14:10:57 AndyS: outlined proposal is to have both DISTINCT path matching operator with new operators to distinguish between counting and non-counting form of arbitrary-length paths 14:11:26 AndyS: everybody gets everything, modulo syntax foo 14:11:33 ... need to get back to Axel's comments regarding blank nodes 14:11:49 EricP: estimate on how much more difficult it is for implementations? 14:11:59 AndyS: another 1/2 implementation of property paths (shared alot). 14:12:17 ... is more work 14:12:32 q? 14:13:14 Sandro: next steps? 14:13:22 AndyS: I keep working writing the specification 14:13:45 Axel email - http://lists.w3.org/Archives/Public/public-rdf-dawg/2012JanMar/0242.html 14:13:47 q+ 14:14:11 Zakim, unmute me 14:14:11 bglimm should no longer be muted 14:14:13 ack next 14:14:27 Sandro: require another LC? 14:14:29 AndyS: yes 14:15:14 AndyS: no formal decision to do it yet. If we address comments, it has to be another LC. No strong desire to do nothing 14:15:46 ... willing to do heavy lifting 14:16:37 bglimm: Do we really want to do this counting / non-counting operator distinction *and* to do DISTINCT 14:16:58 ... in 2 section on operators and DISTINCT it is not clear if these are alternatives to each other or complementary 14:17:32 AndyS: * and + counting/non-counting versions (agreement on this) 14:18:01 ... if we go with DISTINCT, we wouldn't need these operators. Useful to distinguish between applicable algorithms to use and syntax clarification 14:18:10 bglimm: going for both? 14:18:14 AndyS: yes, so far 14:18:21 Zakim, mute me 14:18:21 bglimm should now be muted 14:18:41 q? 14:19:15 ericp: adds syntactic shorthand (doesn't change expressivity)? 14:19:23 AndyS: will change number of answers [..distortion..] 14:20:24 yes 14:20:48 topic: Group schedule 14:20:51 cbuilara_ has joined #sparql 14:21:09 http://www.w3.org/2009/sparql/wiki/Comments 14:21:13 topic: Actions + Comments 14:21:26 + +5697565aaff 14:21:35 zakim, ??5697565aaff is me 14:21:35 sorry, cbuilara_, I do not recognize a party named '??5697565aaff' 14:21:41 - +5697565aaff 14:22:12 AndyS: outstanding comments: PP - 3-4 comments 14:23:15 ericp: have people to delegate comment answering to? 14:23:41 +??P27 14:23:47 zakim, ??P27 is me 14:23:47 +cbuilara_; got it 14:23:48 Zakim, unmute me 14:23:48 chimezie should no longer be muted 14:23:54 zakim, who is on the phone? 14:23:54 On the phone I see ericP, Sandro, AndyS, +1.206.708.aabb, bglimm (muted), SteveH, +1.310.729.aadd, chimezie, pgearon, MattPerry, cbuilara_ 14:24:12 chimezie: one or two outstanding graph store comments from James Lee 14:25:04 Paul - PA-3 ?? 14:25:53 q? 14:26:21 greg: I'd like to talk about the Dave R. comment at some point 14:26:25 zakim, aadd is Greg 14:26:25 +Greg; got it 14:26:42 Comment - DRD-1 : http://lists.w3.org/Archives/Public/public-rdf-dawg-comments/2012Feb/0026.html 14:26:50 Greg: a concern about syntax of PP interfering with future expansion of prefix name syntax 14:27:02 ACTION: Sandro to response to James Lee's commment(s) on Graph Store Protocol, due in two weeks 14:27:02 Created ACTION-603 - Response to James Lee's commment(s) on Graph Store Protocol, due in two weeks [on Sandro Hawke - due 2012-03-20]. 14:27:09 ... I'm worried this opens pandoras box, but if we are in additional LC, we should at least discuss it 14:27:55 ... characters in prefix name has been growing. PP syntax limits this. '/' can never be added to a prefix name, for example 14:28:15 ericp: is he aware backslash can be used for escaping? 14:28:28 Yes - in SPARQL - yes he's aware. 14:29:05 q+ to describe the tension of SPARQL-Turtle compatibility vs. brevity 14:29:07 greg: brought up point regarding CURIEs. worried about adding syntax like that to SPRQL 14:29:11 s/SPRQL/SPARQL 14:29:13 ack aadd 14:29:47 ericp: concern is complexity of implementation or of user experience? 14:29:58 Zakim, mute me 14:29:58 chimezie should now be muted 14:30:15 greg: late in the game to play around w/ syntax (counting syntax notwithstanding) 14:30:31 ... shouldn't be huge implementation burden, however we should decide 14:30:38 ack me 14:30:38 ericP, you wanted to describe the tension of SPARQL-Turtle compatibility vs. brevity 14:31:09 ericp: xml namespace usecase was irritating 14:31:46 ... there was desire to add more characters in SPARQL / Turtle. In the latter, there was tension around ?squatting on character? 14:32:24 ... solution: to use escape mechanism in local names but not property paths. In Turtle, authors bear burden of escaping being on assertion language 14:32:27 s/latter/former 14:32:40 ericp: IMO: this is good enough as it is now and meeting many usecases 14:33:26 AndyS: I agree with Eric. Also, colon character is used in GSP. Desire for prefix name to have colon in local name, but incompatible in turtle 14:33:30 a:b:c:d is valid Turtle -- a:b :c :d . 14:33:49 nice! 14:34:40 AndyS: a matter or preference. CURIEs overload square brackets. Not sure it works out well. 14:35:05 ... not sure if 2 ways for syntax is acceptable (need to right out rules twice) 14:36:15 ericp: no one tried to spec out a grammar. 14:37:23 ericp: content to not require backslash escaping of colon 14:37:31 ... IRC example will require whitespace 14:39:56 ericP: refer to them as 'meta characters' 14:40:09 ... SPARQL local names (and Turtle) have not meta chars (one choice) 14:40:18 ... or escape in SPARQL but not in Turtle (or in both) 14:40:42 ... im inclined to do both 14:42:07 AndyS: take to email? 14:42:21 greg: brought up with RDF WG, we agreed to send to them 14:42:23 AndyS: yes 14:42:44 ... no response 14:44:05 RDF-WG email: http://lists.w3.org/Archives/Public/public-rdf-wg/2012Feb/0103.html 14:46:09 +q 14:46:38 ack next 14:46:47 ack aadd 14:46:51 ack next 14:47:05 Paul: Peter Ansil question: DELETE / INSERT clauses 14:47:17 ... allow them to appear in either order 14:47:28 Peter Ansell 14:47:34 ... if not, clean up examples, but he has a point. Any reason we can't have them interchangeable? 14:47:42 s/Ansil/Ansell 14:47:52 AndyS: DELETE is executed before INSERT and it makes a difference 14:48:13 q- 14:48:41 bye 14:48:44 -chimezie 14:48:44 bye 14:48:47 - +1.206.708.aabb 14:48:47 bye 14:48:47 ADJOURNED 14:48:50 -Sandro 14:48:52 -SteveH 14:48:54 -bglimm 14:48:56 -pgearon 14:49:05 -MattPerry 14:49:07 -cbuilara_ 14:49:07 -Greg 14:52:10 -AndyS 14:52:12 -ericP 14:52:14 SW_(SPARQL)10:00AM has ended 14:52:14 Attendees were +1.617.324.aaaa, ericP, Sandro, AndyS, +1.206.708.aabb, +1.310.729.aacc, bglimm, SteveH, +1.310.729.aadd, pgearon, chimezie, MattPerry, +5697565aaff, cbuilara_, Greg 14:53:58 MacTed has joined #sparql 16:55:11 Zakim has left #sparql
