15:55:09 <trackbot> Zakim, this will be 73394
15:55:09 <Zakim> ok, trackbot; I see SW_RDFWG()11:00AM scheduled to start in 5 minutes
15:55:10 <trackbot> Meeting: RDF Working Group Teleconference
15:55:10 <trackbot> Date: 09 November 2011
15:56:35 <Zakim> SW_RDFWG()11:00AM has now started

15:58:50 <MacTed> I can't make today's call, but hoped I could throw a few words in quickly about graph (and other) identification...
15:58:51 <MacTed> URIs may well be defined as "global in scope" as Pat frequently states -- but people just don't use names or any other identifier consistently in any space, and I am convinced that RDF/WWW/GGG/BBQ will be no different.
15:58:51 <MacTed> Most people may agree that <http://dbpedia.org/resource/Tomato> denotes the red fruit (as the /page/ currently states) -- but plenty of authors will say that it may be a generic term for a woman of the 1920s (see <http://en.wiktionary.org/wiki/tomato>).
15:58:51 <MacTed> Graphs (Gsnaps, Gboxes, Gtexts, etc.) are no different than anything else.  People have used and use do and will use URIs incorrectly.  
15:58:52 <Zakim> +??P4
15:58:54 <MacTed> We have to accept and work with that, or nothing we do will be worth the doing except within the rarified world of logic.
15:58:54 <Zakim> -??P4
15:58:54 <Zakim> +??P4
15:58:57 <MacTed> "Local context" is a fact of life, and RDF having originally been defined *within an isolated context* should not prevent its evolving to recognize that fact.
15:58:59 <swh> Zakim, ??P4 is me

16:13:58 <Zakim> JeremyCarroll should no longer be muted
16:14:04 <ericP> q+ to ask if we want to encourage canonical forms of XSD datatypes
16:14:39 <cygri> jeremycarroll: did we do anything about xsd duration?
16:14:50 <cygri> ... one group improved the duration types
16:15:00 <cygri> ... the type used to be unusable
16:15:18 <cygri> ... the problems with it were fixed somewhere. don't remember where
16:15:33 <sandro> I see http://www.w3.org/TR/xmlschema11-2/ is currently in CR (for 4 months so far).
16:15:42 <cygri> ACTION: JeremyCarroll to check status of duration datatypes
16:15:43 <trackbot> Created ACTION-117 - Check status of duration datatypes [on Jeremy Carroll - due 2011-11-16].

16:16:01 <Zakim> JeremyCarroll should now be muted
16:16:03 <ericP> this is different from owl time which, iirc, atomized the components of the time?
16:16:06 <AndyS> Several technical XML ones - qname, NOTATION, token

16:16:34 <cygri> topic: XSD canonicalization
16:16:34 <Zakim> ericP, you wanted to ask if we want to encourage canonical forms of XSD datatypes

16:17:09 <Zakim> +AZ; got it
16:17:34 <AndyS> q+
16:17:39 <cygri> JeremyCarroll: the canonical form for decimal and int are different
16:18:01 <cygri> ... getting the canonical stuff right is hard
16:18:31 <cygri> davidwood: there were lots of email messages on 1 vs 1.0
16:18:54 <cygri> ericP: and yet it seems to be desirable
16:18:57 <gavinc> I think XSD 2 does a good job of listing the canonical form of all them now?
16:19:09 <AndyS> This is fixed now.
16:19:13 <cygri> davidwood: we could ignore this completely, or do only the simple ones, or do all
16:19:14 <swh> yes
16:19:19 <AndyS> q?
16:20:05 <davidwood> ack AndyS
16:20:18 <cygri> JeremyCarroll: every solution will make someone unhappy. perhaps better to do nothing
16:20:31 <mischat> wishes there was a better solution than http://reference.data.gov.uk/id/gregorian-interval/2010-07-19T00:00:00/P0Y0M0DT0H30M
16:20:35 <cygri> ACTION: JeremyCarroll to summarize issues relating to XSD canonicalization
16:20:35 <trackbot> Created ACTION-118 - Summarize issues relating to XSD canonicalization [on Jeremy Carroll - due 2011-11-16].
16:20:52 <AndyS> http://www.w3.org/TR/xmlschema11-1/
16:20:56 <cygri> AndyS: canonical form for integer changes in XSD 1.1
16:21:04 <cygri> ... integer is now "1", no longer "1.0"
16:21:15 <cygri> davidwood: this might make it tractable for us
16:21:31 <cygri> AndyS: owl has normative dependency on XSD 1.1
16:21:45 <cygri> davidwood: so we almost have an obligation to handle this too
16:21:55 <cygri> AndyS: depends … is this may, should, must?
16:22:05 <JeremyCarroll> zakim, mute me
16:22:05 <Zakim> JeremyCarroll should now be muted
16:22:09 <cygri> davidwood: charter says we should align RDF with other recommendations and best practices
16:22:16 <cygri> ... seems this is worthy of our time
16:22:26 <cygri> AndyS: it's good to put in some text to encourage it
16:22:44 <cygri> davidwood: i'd be happy with a should
16:23:43 <cygri> davidwood: anybody willing to take an action on summarizing the work that would need to be done?
16:23:47 <JeremyCarroll> zakim, unmute me
16:23:47 <Zakim> JeremyCarroll should no longer be muted
16:24:19 <cygri> ... i think that touches semantics too
16:24:22 <cygri> pfps: why?
16:24:35 <cygri> JeremyCarroll: as andy said, the value is what matters
16:24:46 <cygri> ... one school of thought: we don't care how you write down the value
16:25:13 <cygri> ... other school of thought: the value is what you write
16:25:21 <ericP> but RDF has little more logic can graph equivalence so the lexical form is critical
16:25:28 <cygri> ... unlikely that there's consensus
16:25:34 <ericP> q+ to talk about SPARQL
16:25:45 <mischat> fwiw, as it stands, RDF Semantic states that xsd:duration shouldn't be used : http://www.w3.org/TR/rdf-mt/#DTYPEINTERP
16:25:48 <cygri> davidwood: what does SPARQL say about this?
16:25:59 <Zakim> +??P34
16:25:59 <JeremyCarroll> zakim, mute me
16:26:00 <Zakim> JeremyCarroll should now be muted
16:26:11 <cygri> ericP: there's a difference between RDF graph equivalence and xpath equivalence
16:26:14 <yvesr> Zakim, ??P34 is me
16:26:14 <Zakim> +yvesr; got it
16:26:24 <AndyS> q+ to update Eric's answer for SPARQL 1.1 :-)
16:26:30 <JeremyCarroll> machat, yes duration is broken ... iw was well known when xsd 1.0 came out
16:26:38 <davidwood> ack ericP
16:26:38 <Zakim> ericP, you wanted to talk about SPARQL
16:26:40 <JeremyCarroll> they were out of time
16:26:42 <davidwood> ack AndyS
16:26:42 <Zakim> AndyS, you wanted to update Eric's answer for SPARQL 1.1 :-)
16:26:53 <cygri> AndyS: SPARQL 1.1 has D-entailment which gives value-based processing
16:27:04 <cygri> ericP: but that's not regular sparql processing?
16:27:15 <cygri> AndyS: it's not in the lowest form of processing
16:27:29 <cygri> davidwood: you can get around all of that with filters?
16:27:39 <cygri> AndyS: yes, not all engines do it
16:28:36 <cygri> topic: Named Graphs
16:28:46 <davidwood> http://lists.w3.org/Archives/Public/public-rdf-wg/2011Nov/0025.html
16:30:04 <cygri> pfps: i thought named graphs should show up in rdf concepts without changing semantics
16:30:13 <cygri> ... now we talk about changing semantics
16:30:23 <cygri> ... i disagree with a lot of that, and the rest i don't understand
16:30:39 <cygri> davidwood: do you disagree with andy's position on this?
16:31:11 <gavinc> Zakim, mute me
16:31:11 <Zakim> sorry, gavinc, I do not know which phone connection belongs to you
16:31:19 <gavinc> Zakim, who is on the phone?

16:31:33 <Zakim> gavinc should now be muted
16:31:52 <cygri> pfps: i'm worried about the idea that named graphs has to do with the current state of the semantic web
16:32:10 <danbri> I tried to write up the dilbert scenario http://danbri.org/words/2011/11/03/753 just so it's documented as a scenario (without assuming any particular approach)
16:32:12 <JeremyCarroll> q+ to stromgly disagree with peter :)
16:32:13 <pfps> I worry very much about anything that puts the current state of the Web into RDF Semantics.
16:32:39 <JeremyCarroll> zakim, unmute me

16:32:47 <davidwood> ack JeremyCarroll
16:32:47 <Zakim> JeremyCarroll, you wanted to stromgly disagree with peter :)

16:35:26 <JeremyCarroll> me thinks there is a transatlantic misunderstanding about domestic incidents
16:36:29 <davidwood> q?
16:36:49 <cygri> AndyS: in that message i tried to capture the notion that there's a two-stop process in going from trig file to graph. name goes to something, something goes to graph
16:37:02 <cygri> ... the named graphs paper says the relation is "denote"
16:37:23 <cygri> ... n3 says it's the owl:sameAs relation
16:37:37 <cygri> ... but other things are possible. "it's where i downloaded it from"
16:37:57 <gavinc> Zakim, who is talking
16:37:57 <Zakim> I don't understand 'who is talking', gavinc
16:37:58 <cygri> ... that's what ppl often do because it's convenient, even though it's a time-varying relationship
16:38:00 <gavinc> Zakim, who is talking?
16:38:12 <Zakim> gavinc, listening for 11 seconds I heard sound from the following: AndyS (81%), danbri (17%)
16:38:14 <cygri> ... Sandro talked about writing down good practice
16:38:37 <cygri> ... the good practice would be to fix the second step to "denote"
16:38:54 <danbri> yes - good to write down best practice; not clear what best practice actually *is*

16:39:21 <swh> +1 to danbri 
16:40:13 <AndyS> Agree there is > 1 "good practice"
16:40:57 <AndyS> ... maybe, "patterns", or "ways to use the machinery"
16:42:03 <AZ> +1 cygri
16:42:13 <davidwood> q?
16:42:27 <cygri> cygri: i think we can handle "state of the web" without going into semantics
16:43:05 <cygri> ... awww, REST etc already handle "state of the web" well, and it might be less dangerous to leave the relationship of that to the RDF data model a bit fuzzy
16:43:13 <sandro> zakim, who is making noise?

16:45:40 <sandro> q?
16:45:43 <sandro> q+
16:45:48 <cygri> AndyS: i wasn't trying to propose a conceptual model, but find a more concrete way of talking about the machinery
16:46:19 <cygri> ... i prefer the view that there's a loose association between uri and graph
16:46:34 <JeremyCarroll> q+ to suggest using dilbert cube move use case
16:46:36 <cygri> ... with perhaps a way of making it more explicit
16:46:52 <sandro> q-
16:47:13 <cygri> davidwood: i asked kendall clark what a named graph is in stardog
16:47:32 <cygri> ... he said, a possibly empty partition of a database
16:47:43 <cygri> ... that's how many stores treat it
16:47:50 <sandro> "A named graph is a possibly empty partition of an RDF database" -- that's the concept within the RDF database community.
16:48:00 <cygri> ... there's shared conceptual understanding in the rdf database community, but not outside of that community
16:48:37 <JeremyCarroll> zakim, unmute me
16:48:37 <Zakim> JeremyCarroll should no longer be muted
16:48:43 <cygri> AndyS: in databases, the fact that it's a partition is a secondary issue
16:48:51 <cygri> ... the question is, why is it partitioned?
16:48:59 <cygri> JeremyCarroll: i'm unhappy with kendall's phrasing
16:49:31 <cygri> ... when we talk about the web, a named graph is almost like a cached set of triples
16:49:49 <cygri> ... [summarizes webarch]
16:50:33 <cygri> AndyS: your model is a commonly used one ... how does it fit the notion in the named graph paper?
16:51:50 <davidwood> JeremyCarroll, that sounds like Plato's Theory of Forms in that an RDF Graph is only ever abstract and its current home has no particular bearing.
16:52:36 <cygri> JeremyCarroll: a set of named graphs is a cache of the web as defined by web architecture specs
16:53:13 <gavinc> +1 RDF wayback machine
16:53:23 <davidwood> I think JeremyCarroll said that a set of named graphs is a cache of *representations*
16:53:38 <davidwood> Is that so?
16:53:43 <cygri> ... a graph name is a url. webarch already says what's the value of the corresponding graph. it's a solved problem.
16:54:29 <cygri> AndyS: you could write down in your data what purpose you're using the 4th slot for
16:54:37 <cygri> q+
16:54:43 <JeremyCarroll> ack
16:54:47 <JeremyCarroll> q-
16:54:54 <davidwood> ack cygri
16:55:44 <JeremyCarroll> zakim, mute me
16:55:44 <Zakim> JeremyCarroll should now be muted
16:55:51 <davidwood> q?
16:56:14 <ericP> i don't agree that the RDB world does a better job with catalog, etc.
16:56:27 <davidwood> ericP, agreed
16:56:31 <JeremyCarroll> q+ to respond to richard overloading
16:56:34 <ericP> i think that stuff is more about namespace scoping
16:56:55 <cygri> cygri: the fourth element is used for many different things ... once you try using it for one thing, you preclude other uses
16:57:15 <ericP> that i agree with completely
16:57:23 <cygri> AndyS: RDB world is simpler because they don't try to cache the web
16:57:45 <JeremyCarroll> zakim, unmute me
16:57:45 <Zakim> JeremyCarroll should no longer be muted
16:58:04 <davidwood> ack JeremyCarroll
16:58:04 <Zakim> JeremyCarroll, you wanted to respond to richard overloading
16:58:07 <cygri> davidwood: in an RDB you have lots of out-of-band context. in RDF when you share stuff on the web you have to make that context explicit
16:58:26 <cygri> JeremyCarroll: agree that the 4th slot is overloaded
16:58:48 <cygri> ... but the answer is: if you want to have something better, model it better
16:59:12 <cygri> ... 4th element is a simple generic mechanism
16:59:30 <cygri> ... and there's a toolkit for building something more complicated when you need it
16:59:33 <cygri> q+
16:59:44 <JeremyCarroll> zakim, mute me
16:59:44 <Zakim> JeremyCarroll should now be muted
17:00:04 <davidwood> ack cygri
17:00:20 <gavinc> ... why are we trying to do that?
17:00:23 <ericP> cygri: we are trying this 4th element from the "cheap and cheerful" into something much more specific
17:00:57 <ericP> ... we're trying to say explicitly how that 4th col works and tie it to web semantics
17:01:07 <Zakim> -mischat
17:01:09 <ericP> ... i would be happy to keep it "cheep and cheerful"
17:01:23 <yvesr> s/cheep/cheap
17:01:25 <cygri> davidwood: 4th element is an IRI. people can say what it means.
17:01:52 <cygri> AndyS: i agree, but there's a caveat. there's also the relation between IRI and graph
17:01:57 <Zakim> +??P46
17:02:02 <cygri> davidwood: yes
17:02:10 <mischat> zakim, ??P46 is me 
17:02:14 <Zakim> +mischat; got it
17:02:18 <mischat> zakim, mute me 
17:02:38 <Zakim> mischat should now be muted
17:02:39 <ericP> q+ to ask if this goes at all beyond what SPARQL had laid out
17:02:49 <davidwood> ack ericP
17:02:52 <AndyS> q?
17:02:53 <davidwood> q?
17:03:08 <Zakim> ericP, you wanted to ask if this goes at all beyond what SPARQL had laid out
17:03:15 <cygri> ericP: in SPARQL i have a name for a graph and some stuff inside
17:03:16 <cygri> ... i can make assertions about that graph
17:03:20 <yvesr> davidwood, you can't explicitly represent the relation between the IRI and the graph now (having an IRI for the graph is not enough, i guess)
17:03:45 <cygri> ... that's all there is in sparql at the moment
17:03:56 <davidwood> yvesr, right, we still would need to create a relation.
17:04:00 <Zakim> -gavinc
17:04:16 <davidwood> …but we avoid having a single meaning for the 4th slot
17:04:26 <cygri> AndyS: in SPARQL it's always a loose relation except in FROM NAMED where it's the web architeture relation
17:04:42 <yvesr> davidwood, yes
17:04:43 <cygri> ericP: allow bnodes in the 4th place?
17:04:57 <cygri> ... tricky because of scope
17:04:58 <JeremyCarroll> no bnodes in 4th place!!
17:05:04 <gavinc> No.
17:05:07 <davidwood> +1 JeremyCarroll
17:05:10 <Souri> No
17:05:13 <pchampin> but nevertheless, SPARQL suggests that someone can write <graph-iri> dc:creator "pchampin" .
17:05:13 <AZ> literals in the 4th place?
17:05:19 <zwu2> +1 Jeremy
17:05:36 <pchampin> ... which seems to imply that <graph-iri> is *naming* the graph
17:06:08 <cygri> AndyS: the case needs to be made for anything besides IRI in that slot
17:06:08 <Souri> no bNodes in 4th place please
17:06:10 <ericP> i'm happy with the "4th col is an IRI" constraint
17:06:20 <ivan> +1 to Sandro
17:07:30 <cygri> sandro: i want to see some examples of what i can do with the datasets proposal
17:07:57 <cygri> AndyS: there were two examples already
17:08:19 <gavinc> http://dvcs.w3.org/hg/rdf/raw-file/default/trig/index.html#sec-graph-statements ;)
17:08:58 <cygri> sandro: i'm looking for a trig document and a clear notion of what is entailed by it
17:10:23 <cygri> ACTION: AndyS to create a short example for a TriG document and a clear notion of what is entailed by it
17:10:23 <trackbot> Created ACTION-119 - Create a short example for a TriG document and a clear notion of what is entailed by it [on Andy Seaborne - due 2011-11-16].
17:10:46 <davidwood> q?
17:10:48 <JeremyCarroll> zakim, unmute me
17:10:48 <Zakim> JeremyCarroll should no longer be muted
17:10:59 <zwu2> byte, have to go to another meeting.
17:11:01 <gavinc> Sorry, wife needed the phone line for health insurance :\
17:11:09 <Zakim> -zwu2
17:11:12 <Zakim> +[OpenLink]
17:11:31 <MacTed> Zakim, [OpenLink] is OpenLink_Software
17:11:31 <Zakim> +OpenLink_Software; got it
17:11:34 <MacTed> Zakim, OpenLink_Software is temporarily me
17:11:34 <Zakim> +MacTed; got it
17:11:37 <MacTed> Zakim, mute me
17:11:37 <Zakim> MacTed should now be muted
17:11:39 <cygri> JeremyCarroll: once you have an example i'll comment on it regarding correspondance with web architecture
17:11:42 <JeremyCarroll> zakim, mute me
17:11:42 <Zakim> JeremyCarroll should now be muted

17:11:54 <cygri> davidwood: should we just make an issue for this?
17:12:02 <davidwood> ack ivan
17:12:21 <cygri> ivan: reaction on the list convinced me that this would be difficult
17:12:43 <cygri> q+
17:12:55 <davidwood> ack cygri
17:13:00 <cygri> cygri: RDF/RDFS/OWL URIs are too long and unwieldy for use in new tech like microdata. if that ship has really already sailed, then it might be sailing into a dead end
