Maybe we should generalize ??? into a graph resource or whatever. 15:22:15 PatHayes: Anything that can emit graph representations 15:22:40 PatHayes: would encompass the things in SPARQL 15:22:52 s/\?\?\?/g-box/ 15:22:54 Souri has joined #rdf-wg 15:23:01 +Souri 15:23:21 LeeF: A few actions on people to do the sorts of things Pat just talked about.

SPARQL also says this, in effect. 15:27:15 LeeF: does what LeeF said in IRC match what your talking about? 15:27:16 PatHayes, indeed - it does make sense 15:27:26 s/what LeeF said/what yvesr said 15:27:35 Makes sense for default graph. 15:27:38 YEs to all the questions. 15:27:51 q? 15:27:55 In practice, there are multiple ways in which the IRI is associated to a graph in the dataset/store. Used as a indirect association. e.g. same URI as the place contents were read from originally. e.g. true g-snap naming. All are used. 15:28:00 zakim, mute me 15:28:00 AZ should now be muted 15:28:02 q+ 15:28:07 ack PatHayes 15:28:16 i think i agree with pat and i don't think our notion of graph should be tied to http as such 15:28:36 PatH: This concern about the term document. Some people assume that the thing is mutable. 15:29:12 PatH: Thing returned from GET is a Document? 15:29:21 LeeF: Is a Document a mutable thing or not? 15:29:27 no feeling either way 15:29:32 Zakim, unmute me 15:29:32 MacTed should no longer be muted 15:29:39 PatH: I don't think the webArch talks about Documents 15:29:48 that was Andy 15:29:49 s/PatH/Andy 15:30:03 Andy: Document not quiet the info resource 15:30:24 MacTed: Intuition is never really correct 15:30:29 gavin: from our perspective (topq) documents are mutable 15:30:39 gavinc: TopQuadrant position is that documents are mutable, and it's hard to talk about semantic technologies when you're not on the Web 15:30:43 ... or it becomes very hard a=to talk about semantic technologies when you happen to not be on the web 15:30:54 s/and it's hard/or it's hard 15:30:59 ... everybody here does that whether they internalise that or not 15:32:26 s/quiet/quite/ 15:32:34 MacTed: Document is immuatable. As soon as you hit web space, everything is mutable. Unless you have all it's metadata. It's also any specified URI. 15:32:35 From this discussion, it seems that the term Document is not appropriate for "A serialization of an RDF Graph into a concrete syntax." 15:32:37 AWWW - "RDF documents" 4.2.4. -- not defined -- used once 15:32:53 MacTed: terms are overloaded. In web space, all abstract things have extra properties like date, creation. People dont hold this intuitively. 15:33:01 and also xml docments, svg documents 15:33:14 Good examples, Andy. 15:33:29 MacTed: Invent a new term for things that have never been defined. 15:33:31 q+ 15:33:36 ack pchampin 15:33:59 real, physical 3-d documents are still mutable i think unless we go to a lot of trouble (like notarising and such) to make sure they are immutable 15:34:20 pchampin: Document outside the web has many diffrent meanings. I think it's not used in Web Architecture. 15:34:29 As an artist, I can assure you that physical documents are mutable. 15:34:36 pchampin: I like terms resource and representation. Quiet well defined meanings 15:35:05 me too. 15:35:21 LeeF: How would resource and representation map? 15:35:39 pchampin: g-box is an info resource 15:35:42 HOw about "graph data structure" or "graph data object" ? 15:35:50 pchampin: g-box is outside the web, I think I agree with that 15:36:06 Zakim, mute me 15:36:06 MacTed should now be muted 15:36:08 pchampin: g-text is an rdf representation, and a g-box is a resource 15:36:30 +1 15:36:33 +1 15:36:38 pchampin: I think, that's my understand of g-* terms 15:36:46 yes 15:36:48 yes 15:36:56 I think Sandro's original idea was g-box is resource, g-snap is (abstract) state of the resource, and g-text is the rest-representation that the resource emits. 15:36:57 LeeF: g-snap is an RDF Graph 15:37:09 g-snap is also state of g-box at a moment. 15:37:20 +1 Pat, Andy 15:37:30 LeeF: g-box is some sort of resource 15:37:57 resource = graph resource, I assume 15:38:09 PatH: I think Sandro was trying to put our graphs into Rest terms. 15:38:12 Guus, i think so, though we haven't said so directly (Yet) 15:38:32 SPARQL Dataset = { plus zero or more } and SPARQL Graph Store = {} and g-text = a serialization of a g-box 15:39:10 pchampin: It might be too restrictive to say that Sandro was trying to align with web terms. Was also okay with g-box off the web as well 15:39:25 pchampin: Maybe we are just focusing on the web. 15:39:37 True, I agree. OK, slight generalization. But the kind of thing that COULD be on the Web. 15:39:40 pchampin: Good to start with the Web. 15:39:59 souri - Many uses do fit that model, not all though. 15:40:18 LeeF: If we whole heartedly take the web view, does it break down when it's not on the web. 15:40:23 Can there be a web page that is not on the web? 15:40:34 gavinc: yes, it breaks down fairly badly 15:40:41 Pat - hard to say :-) 15:41:01 gavinc: you need to do things like ask for URIs and base URIs of a document on the filesystem 15:41:12 gavinc: ends up being very very weird for peopl editing documents in a filesystem 15:41:30 q+ 15:41:31 gavinc: may be intrinsic to people using a Web technology off the WEb 15:41:36 zakim, unmute me 15:41:36 ww should no longer be muted 15:41:37 ack ww 15:41:39 Hmm, I don't read REST as saying that all resources must be 'on' the web. 15:42:16 ww: I don't see the difference between filesystem paths and URIs? 15:42:31 gavinc: file paths (or URIs) don't behave the same way that HTTP URIs do 15:42:51 gavinc: when i talk about a URI, I'm inevitably talking about an HTTP URI ... but on my machine, I don't want to go off and resolve the URL, I just want to find it on my local machine 15:42:51 s/I don't see the difference/how exactly is it different/ 15:43:09 gavinc: XML _sort of_ solves this with XML Catalogs, but RDF doesn't really have anything that deals with this 15:43:27 gavinc: SPARQL solves this by lying - it says that I have a URI U, and I resolve it by looking it up in my local database 15:43:27 q+ 15:43:40 zakim, mute me 15:43:40 ww should now be muted 15:43:41 I don't agree with gavinc 15:43:44 gavinc: a lot of machinery to make you look like you're on the Web when you're not 15:43:59 PatHayes: nowhere in RDF where URIs are required to be resolvable 15:44:04 PatH: You don't have to do any GETs at all. 15:44:04 ... except maybe in owl:import 15:44:22 I disagree with gavinc as well. There is an URI loosely associated with a graph - not a deref promise 15:44:25 gavinc: part of it is that our software depends heavily on owl:impport 15:45:14 +1 to AndyS1 (liar is too strong a word! :-)) 15:45:57 local distortion in the truth-field. 15:46:31 @Pat, do you mean a Reality Distortion Field? :-D 15:47:19 LeeF: gavinc, are you looking for terms that are more neutral yet map to resource/representation in a Web context and map to more familiar concepts to people working not on the Web? 15:47:29 gavinc: maybe, but i'm not sure how strongly i feel about it - there is value in reusing the Web terms 15:47:32 AndyS: There is what SPARQL 1.0 says about Datasets, and in 1.1 the Graph Store is a mutable dataset. 15:47:55 ... You do end up with a degree of impersise naming going on. 15:48:06 ... the graph is a set of mutable slots you can go and change. 15:48:10 q? 15:48:13 ack PatHayes 15:48:37 so, a graph store has slots (g-boxes?) to contain g-snaps? 15:48:42 AndyS: The cat is out of the bag. 15:48:58 AndyS: You can't really change the behavior of developers 15:49:01 and when you put/pull a graph you send/get a g-text/ 15:49:02 +1 to AndyS 15:49:18 people have already evolved usage patterns 15:49:19 +1 to Andy 15:49:28 AndyS: Developers are going to be using it.

We have a reasonable number of people using RDF and everyone talks about graph, and no one is too confused. 15:52:10 +SteveH 15:52:10 Can we capture what we are discussing in terms of ISSUE, and try to advance towards proposing ACTIONs? 15:52:30 SteveH: People are abusing/missuing the term for named graphs 15:52:45 s/SteveH/AndyS/ 15:53:12 ACTION-64? 15:53:12 ACTION-64 -- Richard Cyganiak to propose labels for g-text, g-snap -- due 2011-06-29 -- OPEN 15:53:12 http://www.w3.org/2011/rdf-wg/track/actions/64 15:53:41 PatHayes: if we try to keep the word 'graph' in our terms, that might help.

And another would be to just be informative. 16:00:50 (other than specific editorial comments) 16:01:00 PatH: There are one or two place where from our perspective the document seems inconstant 16:01:35 alright I can do that 16:01:41 LeeF: Can we get a few people to review the SPARQL review? 16:01:55 PatH: I will. 16:01:57 ACTION: Pat to review Pierre-A's comments on SPARQL graph store upade protocol 16:01:57 Created ACTION-67 - Review Pierre-A's comments on SPARQL graph store upade protocol [on Patrick Hayes - due 2011-07-06]. 16:02:17 ACTION: Antoine to review Pierre-A's comments on SPARQL graph store upade protocol 16:02:17 Created ACTION-68 - Review Pierre-A's comments on SPARQL graph store upade protocol [on Antoine Zimmermann - due 2011-07-06]. 16:02:32 AndyS: Wouldn't recommend too strong alignment, as we haven't nailed it down ourselves. 16:02:51 -SteveH 16:02:56 LeeF: Sorry if it was a little less directed and focused. 16:03:05 thanks and bye 16:03:16 byebye 16:03:18 -zwu2 16:03:19 LeeF, what exactly was it I agreed to do at the beginning of the meeting? 16:03:23 -yvesr 16:03:24 thanks bye 16:03:24 -LeeF 16:03:26 -MacTed 16:03:28 -mischat 16:03:32 -AlexHall 16:03:34 -ww 16:03:34 PatHayes, use CommonScribe to generate the non-draft version of last week's minutes 16:03:34 AlexHall has left #rdf-wg 16:03:36 -mbrunati 16:03:38 -AZ 16:03:42 -AndyS1 16:03:42 mbrunati has left #rdf-wg 16:03:46 -Souri 16:03:48 -gavinc 16:03:50 -PatHayes 16:03:55 -Scott_Bauer 16:03:55 @PayHayes, I think you agreed to publish last week minutes 16:03:58 rrsagent, make records public 16:04:34 -pchampin 16:04:35 SW_RDFWG()11:00AM has ended 16:04:39 Attendees were ww, Scott_Bauer, gavinc, yvesr, LeeF, AndyS1, AZ, pchampin, AlexHall, zwu2, PatHayes, MacTed, mbrunati, SteveH, mischat, Souri 16:14:47 cygri has joined #rdf-wg 17:40:34 AndyS has joined #rdf-wg 18:04:35 gavinc has left #rdf-wg 18:26:07 Zakim has left #rdf-wg
