OTOH, based on submission, possible that LDP impls could use graph stores as back end(s) 14:18:09 +mhausenblas 14:18:28 ... GSP requires 1 of 3 formats if request omits Accept header. LDP requires Turtle only, so gap. 14:18:30 Michael: Sorry for being late, prev meeting took longer than expected 14:18:45 this I suppose http://www.w3.org/TR/sparql11-http-rdf-update/ 14:19:21 ... GSP wording of POST says it's a merge, LDP says it depends on the resource - BP resource = undefined, BP container = creating new resource and adding new resource's URI to the container 14:20:19 q+ if squinting would get us test-case compatibility 14:20:23 q+ to ask if squinting would get us test-case compatibility 14:20:30 ... POSTing to graph store URI = add new graph to graph store, at uri assigned by GS. No definition of semantics of GET on GS URI. 14:20:56 ... "squinting" says some similarities at least. 14:21:45 ericp: sparql WG issue - does saying that POST means append "force the hand" of implementations not claiming to be a GS. 14:23:55 ...e.g. append could be notional, whole bunch of triples show up (new membership in container, new resource) others change (last page != nil). *Could* say that GSP applies to resources created (e.g. asset in submission ex), others LDBP containers, and GSP does not control what happens in LDBP containers. Only way I can see claiming conformance to both in single impl. 14:24:16 q+ 14:24:27 ack ericp 14:24:27 ericP, you wanted to ask if squinting would get us test-case compatibility 14:24:42 who is speaking about sparql impl? 14:24:43 q+ 14:24:49 ack ashok 14:25:33 ashok: should we be thinking about how to align them? 14:25:47 q? 14:25:53 ericp: could parameterize GSP, so there's an append type of resource 14:25:58 q+ to talk about procedure 14:26:50 arnaud: GSP is in Last Call, what is sense from WG on whether it is likely to proceed vs WG being eager to make changes, [implication: as alignment might require]? 14:28:05 ack dret 14:28:07 ericp: no time to waste, expect Rec by end of year. WG added language to narrow scope down to SPARQL only, not general HTTP access to RDF. If LDP WG thinks GSP is harmful to the Web, LDP would have to object. Spec might well die if that happened. 14:28:10 q- 14:28:24 s/ericp:/sandro:/ 14:29:23 q+ to talk about sparql service description 14:29:56 dret: any problem separating them cleanly from a rest perspective, so an implementation could offer one link for each protocol? that the way to do it from REST perspective. "Home" resource, "dispatch" with 1 link for GSP, 1 for LDP. 14:29:57 ack ericp 14:29:57 ericP, you wanted to talk about sparql service description 14:29:58 q+ on home page 14:30:01 sando: could work 14:30:13 q+ 14:30:56 cygri has joined #ldp 14:31:11 ericp: service desc could differentiate the resources it owns/manages. Not sure if I can say I have a GS if only some of its resources adhere to GSP. 14:31:11 ack bblfish 14:31:11 bblfish, you wanted to comment on home page 14:31:16 zakim, i'm with mhausenblas 14:31:16 +cygri; got it 14:31:28 general home document work: https://datatracker.ietf.org/doc/draft-nottingham-json-home/ (probably will be extended to cover XML as well) 14:32:37 - +1.512.433.aabb 14:32:40 bblfish: (henry story) home page work reminds one of atom's service page discussion, resource should describe itself. 14:33:01 sandro: that is how sparql serv desc works, but that only applies to sparql endpt not to member resources 14:33:15 henry: link header for metadata? 14:33:50 Atom(Pub) can use 'service' links so that any interaction with a Atom feed or entry can link to the AtomPub service document. 14:33:52 ack steves 14:34:11 sandro: would work, no one mandating it tho. sparql WG chose not to define that, they wanted something simple and this aspect was an add-on they had little experience with, not core to their work. 14:35:03 resources could link to both service documents, if they are served by a container implementing two access models. clients then could choose which one to follow. 14:35:34 AndyS has joined #ldp 14:36:53 technical solution could just be providing RDF type information for the resource, using an HTTP Link header with an rdf:type property. 14:36:55 steves: LDP container proposal was one of several. did discuss link header(s) too, open if we wanted to change it. not sure what it would look like if mixed with GSP. Could highlight as indep way to access same resources, could define a mapping from LDP to GSP, could make some changes in LDP spec to improve alignment, perhaps recommend how POST works if an impl wants to offer both protocols. 14:37:20 sandro: this WG could suggest they add headers/whatever, w/in LDP's scope 14:37:44 oberger has joined #ldp 14:37:46 arnaud: any opinions on whether or not LDP should make any comments on GSP? 14:38:14 AndyS, you here? 14:38:15 perhaps we should leave this issue open. I need to look at it more carefully myself ot understand the issue 14:38:42 sandro: no strong need to hold GSP up 14:38:52 ...others might see such a need, if so should speak up 14:39:02 -ericP 14:39:03 steves: no reason to hold them up 14:39:16 perhaps just put a summary on the wiki 14:39:19 so we can refer to it 14:39:31 +ericP 14:39:34 arnaud: thanks steve for investigating. fulfilled your part. 14:40:26 s/ ot / to / 14:40:57 action: arnaud to add topic on wiki on LDP vs GSP on home page 14:40:57 Created ACTION-13 - Add topic on wiki on LDP vs GSP on home page [on Arnaud Le Hors - due 2012-09-24]. 14:41:06 wow ACTION 13 :-) 14:41:22 * touch typists are dangerous ;-) 14:41:47 trackbot, close action-4 14:41:47 ACTION-4 Review SPARQL Graph Store Protocol and suggest how we should move forward with it closed 14:42:11 bblfish: consent to close action, can always re-open later if new material comes up 14:42:32 topic: use case document 14:42:59 mike and ram working on document 14:43:05 topic: spec draft 14:43:36 steves: working on tool setup, pretty much done. will not make any changes aside from things required to fit it into the template. 14:43:57 arnaud: you reviewed timeline, ok with it? 14:44:00 steves: y 14:44:14 topic: WG time line 14:45:46 +1 to the timeline 14:45:47 i will add it to the wiki 14:45:53 arnaud: chairs took action last time to create time line, went through the right to left schedule exercise, posted. 14:45:59 http://www.w3.org/2012/ldp/wiki/Main_Page#Timeline 14:46:19 give me a minute, i'll update it now that we have approved it 14:46:19 need to update that link 14:46:54 steves: tracker is not linking in email activity, e.g. on 11 I do not see discussion threads. is that a setup problem? 14:48:10 trackbot, close action-11 14:48:10 ACTION-11 Define a timeline for working on the editor's draft and the FPWD (chairs action, i.e. Arnaud and dret) closed 14:48:53 action on yves to Look at tracker config to ensure when an issue is mentioned in an email that the action is updated with the email thread. 14:48:53 Sorry, couldn't find user - on 14:49:08 action yves to Look at tracker config to ensure when an issue is mentioned in an email that the action is updated with the email thread. 14:49:13 Created ACTION-14 - Look at tracker config to ensure when an issue is mentioned in an email that the action is updated with the email thread.
