14:02:54 <bglimm> LeeF: next meeting, as usual (Tue 14th)
14:02:59 <NickH> Zekim, ??P21 is me
14:03:09 <sandro> regrets next week
14:03:12 <ivan> I may be at risk
14:03:15 <LeeF> zakim, ??P21 is NickH
14:03:15 <Zakim> +NickH; got it
14:03:42 <LeeF> topic: JSON Results Format
14:03:47 <bglimm> Topic: JSON results format
14:04:03 <LeeF> http://www.w3.org/TR/rdf-sparql-json-res/
14:04:17 <bglimm> LeeF: First WG published this doc as a WG note
14:04:39 <Zakim> +??P26
14:04:41 <AlexPassant> Zakim, ??P26 is me
14:04:44 <Zakim> +AlexPassant; got it
14:04:44 <bglimm> ... contains a JSON version of the standard XML results format
14:05:13 <chimezie> chimezie has joined #sparql
14:05:24 <bglimm> ... didn't go through the normal standardisation process since it is a note (no implementations required for example)
14:05:44 <chimezie> Zakim, what is the passcode?
14:05:44 <Zakim> the conference code is 77277 (tel:+1.617.761.6200 tel:+33.4.26.46.79.03 tel:+44.203.318.0479), chimezie
14:05:49 <bglimm> ... seem popular in practise, several implementations
14:06:08 <Zakim> +Chimezie_Ogbuji
14:06:13 <bglimm> ... Should we publish it as real standard?
14:06:39 <bglimm> ... Would cause more work in terms of test cases, reviews, etc
14:06:44 <NickH> I think making JSON an offical standard is really important
14:06:56 <kasei_> +1 (would also like to see jsonp support)
14:07:02 <SteveH> +0.5
14:07:05 <bglimm> ... I would like to hear opinions about this
14:07:06 <NickH> will really help adoption
14:07:14 <sandro> +0.5
14:07:22 <bglimm> NickH: We use JSON a lot at BBC
14:07:38 <chimezie> Zakim, mute me
14:07:38 <Zakim> Chimezie_Ogbuji should now be muted
14:07:38 <bglimm> ... easy to parse, many developers know it, would help adoption of SPARQL
14:07:39 <chimezie> +1
14:07:57 <SteveH> yes, terrified of toppling over
14:07:59 <ivan> q+
14:08:00 <SteveH> :)
14:08:02 <sandro> yes, that's why I didnt say "+1"
14:08:13 <AlexPassant> never used XML/SPARQL and works only w/ JSON, so also happy to have it as a rec
14:08:14 <bglimm> LeeF: I see a lot of support on IRC. Is anybody worried about this additional burden?
14:08:22 <bglimm> IvanH: Do we have editors?
14:08:33 <Zakim> +pgearon
14:08:44 <bglimm> LeeF: The doc does not need much work, we could keep the note editors
14:08:44 <pgearon> apologies for tardy arrival
14:08:54 <pgearon> muted
14:09:36 <bglimm> IvanH: Before making a decision, we should make sure we have editors who take responsibility for the document and the work this will cause. 
14:09:52 <bglimm> ... We might want to look at this when other docs are in LC. 
14:10:28 <ivan> q?
14:10:36 <bglimm> LeeF: I wouldn't make a decision before we have editors, but I want to see how much support this would have.
14:10:37 <LeeF> ack ivan
14:11:12 <bglimm> IvanH: We have the questionnaire for next steps for RDF and we might have a JSON format for RDF
14:11:45 <AlexPassant> would also require a return format for Update (simple 'success' / 'failure' pattern)
14:12:06 <pgearon> I think that JSON is possibly more used than XML is at the moment
14:12:13 <bglimm> ... The current JSON for SPARQL format does not cover constructs, but could possibly be combined with the JSON for RDF and cover costructs this way
14:12:18 <LeeF> ACTION: Lee to work with Axel to identify potential editor(s) to shepherd through JSON document on Rec track
14:12:18 <trackbot> Created ACTION-306 - Work with Axel to identify potential editor(s) to shepherd through JSON document on Rec track [on Lee Feigenbaum - due 2010-09-14].
14:12:46 <bglimm> LeeF: If anybody is interested in an editorial role for this please contact me and/or Axel
14:12:58 <bglimm> Topic: Test Cases
14:13:17 <bglimm> LeeF: We can hopefully approve some more test case sets
14:13:25 <LeeF> group_concat test cases: http://lists.w3.org/Archives/Public/public-rdf-dawg/2010JulSep/0272.html
14:13:30 <bglimm> ... some from greg for GROUP_CONCAT
14:14:08 <bglimm> ... there are two plus one from a later date
14:14:39 <LeeF> agg-groupconcat-1
14:14:43 <LeeF> agg-groupconcat-2
14:14:48 <bglimm> ... AndyS reported that ARQ passes the two older ones
14:14:55 <kasei_> I think the third duplicates the first, but also adds the separator.
14:15:06 <kasei_> I pass them
14:16:01 <bglimm> LeeF: The difference between the first and the third is that the third uses a non-default separator
14:16:37 <bglimm> ... Since the order of the rows in an aggregate is not specified, you can get multiple strings
14:17:22 <bglimm> ... Greg used a FILTER to test for the possible orders, useful way of abstracting from the fact that we need implicitly have an order
14:17:25 <LeeF> PROPOSE: Approve tests agg-groupconcat-1, agg-groupconcat-2, and agg-groupconcat-3
14:17:57 <kasei_> +1
14:17:57 <pgearon> Seconded
14:18:42 <bglimm> SteveH: You want to abstain as for past test cases?
14:18:48 <LeeF> RESOLVED: Approve tests agg-groupconcat-1, agg-groupconcat-2, and agg-groupconcat-3
14:18:53 <bglimm> SteveH: I'll check them later
14:19:23 <LeeF> project expression tests: http://www.w3.org/2009/sparql/docs/tests/data-sparql11/project-expression/
14:19:24 <bglimm> LeeF: We have 7 tests for project expressions
14:19:28 <LeeF> zakim, who's on the phone?
14:19:28 <Zakim> On the phone I see bglimm, kasei, SteveH__, Ivan, LeeF, OlivierCorby, MattPerry, Sandro, NickH, AlexPassant, Chimezie_Ogbuji (muted), pgearon
14:19:52 <bglimm> OlivierCorby: I created these tests
14:19:56 <LeeF> Andy - http://lists.w3.org/Archives/Public/public-rdf-dawg/2010JulSep/0302.html - ARQ passes all 7
14:20:13 <bglimm> LeeF: AndyS reported that ARQ passes these 7 tests
14:21:07 <bglimm> kasei: Are these the test with * in addition to variable lists?
14:21:16 <bglimm> OlivierCorby: I corrected that.
14:21:26 <LeeF> PROPOSE: Approve tests projexp01 - projexp07
14:21:40 <bglimm> kasei: I think my system passes these tests
14:21:45 <kasei_> +1
14:21:57 <bglimm> LeeF: Any objections, abstains?
14:22:01 <LeeF> RESOLVED: Approve tests projexp01 - projexp07
14:22:04 <kasei_> s/I think//
14:22:35 <bglimm> LeeF: Axel suggested some tests for entailments
14:23:04 <LeeF> entailment test cases: http://lists.w3.org/Archives/Public/public-rdf-dawg/2010JulSep/0313.html
14:23:18 <LeeF> bglimm: Axel's question was whether the surrogate blank nodes introduced should be returned
14:23:24 <LeeF> bglimm: ...and the answer is "no"
14:23:49 <bglimm> LeeF: Is that in CVS?
14:23:58 <bglimm> bglimm: I am not sure whether Axel added this.
14:24:10 <bglimm> bglimm: I will add this
14:24:33 <LeeF> ACTION: Birte to add Axel's two surrogate blank node test cases to CVS
14:24:33 <trackbot> Created ACTION-307 - Add Axel's two surrogate blank node test cases to CVS [on Birte Glimm - due 2010-09-14].
14:25:11 <bglimm> LeeF: There were discussions about SPARQL Update, triggered by Andy's review
14:25:29 <bglimm> ... Is that just rewording or is tehre anything we need to discuss
14:25:49 <bglimm> OlivierCorby: It is some rewording and some details for the formal update model
14:26:04 <bglimm> ... we will finish the formal model by the end of the week and get another review then
14:26:21 <LeeF> s/OlivierCorby/AlexPassant
14:26:22 <bglimm> ... I have not yet checked what was identified as issues
14:26:51 <bglimm> LeeF: I am interested in the model and I can check it once it is finalized
