15:29:31 <MattPerry> ... the other question is how do we describe/discover the graph store service 15:30:12 <MattPerry> sandro: for question 1, the SPARQL endpiont URI is not necessarily related to the graph store service URI 15:30:30 <MattPerry> ... a lot of people may think they are the same 15:31:28 <MattPerry> sandro: does this get rid of the notion of a servcie URI?

15:37:44 <MattPerry> kasei: test status are current, but implementation status has changed a bit 15:37:57 <LeeF> :-) 15:38:11 <MattPerry> AndyS: couple of small details that were changed in the test 15:38:20 <MattPerry> .... just fixing mistakes 15:38:35 <MattPerry> kasei: those changes look fine to me 15:38:46 <MattPerry> ... would be good if someone else looks at them 15:38:58 <MattPerry> LeeF: they look fine to me, but I have not looked in detail 15:39:27 <kasei> if we have time, I'd like to discuss the COPY/MOVE tests that I emailed the list about. 15:39:40 <axelpolleres> PROPOSED: approve all non-approved test cases at http://www.w3.org/2009/sparql/implementations/#sparql11-federated-query 15:39:58 <LeeF> Seconded. 15:39:58 <kasei> +1 15:40:03 <AndyS> +1 15:40:03 <axelpolleres> +1 15:40:06 <cbuilara> +1 15:40:18 <axelpolleres> RESOLVED: approve all non-approved test cases at http://www.w3.org/2009/sparql/implementations/#sparql11-federated-query 15:40:45 <AndyS> (cbuilara? - were the changes OK with you?) 15:40:56 <MattPerry> axel: also have 100% coverage on the query language tests 15:41:04 <LeeF> big kudos to Andy and Greg as shining examples for the rest of the SPARQL implementation world! 15:41:18 <axelpolleres> PROPOSED: approve all non-approved test cases at http://www.w3.org/2009/sparql/implementations/#sparql11-query 15:41:22 <LeeF> seconded 15:41:33 <AndyS> +1 15:41:38 <MattPerry> +1 15:41:44 <kasei> +1 15:42:05 <axelpolleres> RESOLVED: approve all non-approved test cases at http://www.w3.org/2009/sparql/implementations/#sparql11-query 15:42:22 <kasei> q+ 15:42:30 <MattPerry> axel: Update Tests: still don't have 100% coverage 15:42:43 <LeeF> ack kasei 15:43:10 <MattPerry> kasei: found some significant problems with the update shortcuts 15:43:45 <MattPerry> ... the text says COPY/MOVE equivelent to e.g. DROP + MOVE, but is this really the case? 15:43:52 <LeeF> I've reviewed Greg's notes and agree that the definitions are broken as-is. 15:44:11 <MattPerry> s/DROP + MOVE/DROP + ADD 15:44:15 <AndyS> Suggestion - let's not approve the update tests today, discuss on email, and move on to the easy ones we can pass (results formats). Need Paul as update editor. 15:44:35 <AndyS> The tests are excellent in finding this. 15:45:00 <MattPerry> kasei: copy graph to itself intuitively should be a no-op but strictly following the spec gets rid of the graph 15:45:00 <axelpolleres> COPY/MOVE definitions need to be fixed in terms of calling them shortcuts 15:45:20 <pgearon> I agree with kasei on the problems with the language inconsistency 15:46:17 <MattPerry> pgearon: The language inconsistency should be fixed 15:46:53 <chimezie> Zakim, mute me 15:46:53 <Zakim> chimezie should now be muted 15:47:04 <MattPerry> pgearon: I'd be inclined to use the equivalent operations and say if it's the same graph it becomes a no-op 15:47:30 <MattPerry> kasei: still have the issue of 1 operation vs a set of operations 15:47:38 <AndyS> q+ 15:47:58 <MattPerry> ... are the shortcuts atomic? 15:48:19 <MattPerry> LeeF: greg, would you prefer atomic or not? 15:48:26 <axelpolleres> ACTION: Paul to suggest some fixing of the wording regarding COPY/MOVE equivalent operations (reagrding atomicity and remarking that some are no-op) and about failure on empty graphs 15:48:26 <trackbot> Created ACTION-585 - Suggest some fixing of the wording regarding COPY/MOVE equivalent operations (reagrding atomicity and remarking that some are no-op) and about failure on empty graphs [on Paul Gearon - due 2012-02-07]. 15:48:59 <MattPerry> kasei: I'd be happy to not require the shortcuts but don't think this is an option 15:49:49 <MattPerry> AndyS: the word atomic is used in 2 different places 15:50:04 <MattPerry> .. for update requests and in the formal definitions 15:50:17 <MattPerry> ... I don't think it needs to be in the formal section 15:50:37 <axelpolleres> "By 'atomic operation' we mean that the operation performs the described transformation of the Graph Store either completely or leaves the Graph Store unchanged, i.e., the result is either GS' or GS (in case of error)." 15:51:15 <MattPerry> ... If we remove atomic from the formal section, this may fix the problem 15:51:50 <LeeF> kasei, if the word "atomic" were removed from the formal definition of an operation, would you be OK with that? 15:52:15 <kasei> LeeF: the word? or that whole sentence? 15:52:41 <MattPerry> AndyS: if there is no reference to SILENT in the formal section, then error handling is outside of the formal definition 15:52:49 <kasei> s/LeeF:/LeeF,/ 15:53:00 <LeeF> the word, I guess? 15:53:07 <LeeF> But I guess the whole sentence 15:53:08 <LeeF> now that I read it 15:53:09 <LeeF> :) 15:53:43 <MattPerry> LeeF: removing "atomic" removes a requirement 15:53:47 <kasei> q+ 15:53:54 <LeeF> ack AndyS 15:54:07 <MattPerry> AndyS: you could say these operations describe the before and after state of the graph store 15:54:11 <pgearon> +q 15:54:54 <MattPerry> axel: I think you're right that we can drop it 15:55:06 <axelpolleres> q? 15:55:16 <AndyS> ack kasei 15:55:23 <MattPerry> kasei: I'm worried that we are going to require code changes 15:55:34 <LeeF> It's a bug fix 15:55:36 <MattPerry> ... for people that used the equivalent expanded form 15:56:14 <axelpolleres> Agreement to remive "atomic" from http://www.w3.org/TR/sparql11-update/#def_updateoperation? 15:57:19 <MattPerry> s/remive/remove 15:57:53 <LeeF> ack pgearon 15:58:13 <MattPerry> pgearon: I'm concerned about a non-atomic implementation during concurrent queries 15:58:21 <MattPerry> ... is this ok? 15:59:07 <MattPerry> AndyS: is it the overall request that should be atomic? 15:59:26 <MattPerry> pgearon: what about while the update is processing 15:59:52 <AndyS> ping - formats tests?
