- 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.

- +??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.

- 15:58:57 [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.

- ... getting the canonical stuff right is hard
- 16:18:31 [cygri]

- 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.

- 16:21:04 [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]

- ... 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

- 16:26:53 [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: 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

- Zakim, who is talking
- 16:37:57 [Zakim]
- I don't understand 'who is talking', gavinc

- 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"

- 16:42:27 [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]

- 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

- 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]

- 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

- 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]

- 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
- 17:01:04 [gavinc]
- IRI ;)

- 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]

- 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]
