16:19:36 <FabGandon> Ivan: the changes in the datatypes may affect us too
16:19:59 <davidwood> I see "Conforming implementations may now support ·primitive· datatypes and facets in addition to those defined here."
16:20:49 <FabGandon> Ivan: there might be changes for instance in data comparison
16:21:10 <davidwood> " this allows float and double to treat positive and negative zero as distinct values, but nevertheless to treat them as equal for purposes of bounds checking" (!) :)
16:21:25 <davidwood> ^^ These things are important to end users, after all
16:21:41 <FabGandon> erciP: is there anyway for the structure to have an impact our data model ?
16:22:12 <FabGandon> Ivan: my opinion is that we are not affected by structure
16:23:06 <FabGandon> ... but the RDF semantics makes a selection of the datatype and this may have to be reviewed.
16:23:35 <davidwood> Topic: RDF-ISSUE-82 (TriG repeated graph iris)
16:24:28 <AndyS1> q+
16:24:35 <ivan_> q-
16:24:36 <FabGandon> gavinc_: consensus on the second option changing "merge" to "union", blank nodes with the same plabel are considered the same
16:25:34 <ScottB_> ScottB_ has joined #rdf-wg
16:25:58 <FabGandon> ... no semantics for blank nodes between graphs with different labels
16:26:32 <FabGandon> ... inference graphs are kept different and are an example where same labels may mean same nodes
16:27:25 <FabGandon> ... no equivalent in RDF/XML or Turtle right now.
16:27:41 <MacTed> Zakim, unmute me
16:27:41 <Zakim> MacTed should no longer be muted

16:28:54 <gavinc_> "In a TriG document graph statements with the same graph IRI should be
16:28:56 <gavinc_> unioned to form a single RDF Graph. Blank nodes in each graph
16:28:57 <gavinc_> statement with the same label are considered to be the same blank
16:28:59 <gavinc_> node."
16:29:03 <FabGandon> davidwood: any objection to the wording (strawpoll) 
16:29:18 <MacTed> +1
16:29:31 <FabGandon> ... we have a consensus
16:30:08 <gavinc_> RESOLVE to close ISSUE-82 with the wording: "In a TriG document graph statements with the same graph IRI should be unioned to form a single RDF Graph. Blank nodes in each graph statement with the same label are considered to be the same blank node."
16:31:45 <davidwood> Topic: Named Graphs
16:31:48 <ericP> davidwood: +☮
16:32:27 <gavinc_> also on the wiki http://www.w3.org/2011/rdf-wg/wiki/Example_of_Endorsement_Use_Case
16:32:38 <FabGandon> davidwood: starting with the endorsement use case
16:32:42 <AZ> AZ has joined #rdf-wg
16:33:38 <FabGandon> ... does anyone push this use case ?
16:34:03 <FabGandon> MacTed: this use case could become very important
16:34:45 <LeeF> We don't ourselves do this sort of endorsement today, nor do our customers.
16:34:56 <gavinc_> It is a current use case for Lex Machina, Inc :D
16:35:18 <davidwood> OK, good
16:35:21 <FabGandon> ... there is a difference between me asserting and me endorsing
16:36:12 <Zakim> +??P39

16:38:23 <Zakim> +AZ
16:41:14 <gavinc_> The hash system in my example DOES NOT require trusting much at all
16:41:48 <gavinc_> +q
16:42:15 <FabGandon> AndyS:  controling the domain name of a graph name does ensure the trust i.e. there is a whole chain e.g. DNS
16:42:47 <ericP> i thought the point of this was to say "it's within..."
16:43:18 <FabGandon> ... the hash gives you stability / repeatability 
16:43:55 <FabGandon> gavinc_: endorsing without hashing may not be very useful
16:44:32 <FabGandon> ericP: within your store you can rely on your architecture 
16:45:27 <cgreer> q+
16:45:32 <gavinc_> -q
16:46:32 <FabGandon> AndyS: a lot of this can be done working with documents
16:46:51 <davidwood> ack cgreer
16:47:38 <FabGandon> cgreer: you don't want to endorse a graph that is merged with an other one.
16:48:31 <FabGandon> gavinc_: my example works because there is an intermediary doc
16:49:12 <FabGandon> ericP: can the provenance wg help here ?
16:49:46 <FabGandon> AndyS: no they are at the URI level
16:54:10 <FabGandon> davidwood: is the problem linked to the question of whether we name graphs with URI or not?
16:55:40 <FabGandon> ivan: the general mechanism is we have a URI and we have a predicate
16:55:59 <Guus> q+ to ask which mechanism
16:56:27 <Guus> +1 with Andy
16:57:14 <Guus> quints are out of scope, I would suggest
16:57:20 <davidwood> ack Guus
16:57:20 <Zakim> Guus, you wanted to ask which mechanism
16:58:26 <ericP> +1 to octs
16:58:55 <davidwood> -1 to octs :)
16:59:08 <FabGandon> gavinc_: we can adapt the syntax without making them quints

17:04:02 <Guus> q+
17:04:37 <cgreer> RDF doesn't disallow inconsistent graphs (+1 Guus)
17:04:47 <FabGandon> ivan: one problem was when in OWL the types of merged containers are disjoint 
17:04:56 <davidwood> ack Guus
17:05:15 <FabGandon> Guus: I'm interested in the easy syntax
17:06:29 <FabGandon> ... examples of syntax would help the discussion
17:07:37 <FabGandon> proposing : ACTION: Guus to write down an example of the syntaxes for the named graphs 
17:08:33 <FabGandon> Ivan: we could publish a version of Turtle tomorrow
17:09:09 <FabGandon> ... without changing it too much
17:09:47 <FabGandon> ACTION: Guus to write down an example of the syntaxes for the named graphs
17:09:48 <trackbot> Created ACTION-137 - Write down an example of the syntaxes for the named graphs [on Guus Schreiber - due 2012-02-01].
17:10:34 <Guus> q+
17:10:59 <davidwood> ack Guus
17:10:59 <FabGandon> ivan: then we have to decide whether or not we modify the RDF semantics 
17:12:14 <FabGandon> Guus: nobody has yet come up with a clear proposal to update the semantics
17:14:57 <Zakim> -gavinc
17:15:19 <FabGandon> ivan: we need at least to write down in plain english the definitions of the core primitives
17:15:48 <MacTed> +1 Ivan's summary, "Named Graph" is inherently ambiguous, and must be defined multiply, for different contexts
17:17:43 <LeeF> I think we may be kidding ourselves if we think we're gong to get high-interoperability with defining this stuff multiple ways
