<trackbot> Meeting: RDF Working Group Teleconference

<trackbot> Date: 27 February 2013

<AndyS> Partial regrets - I can only attend for about 45 mins.

<scribe> scribe: AZ

Admin

gavinc_: there should be a page about the CR
... before Turtle being published we agreed to produce a document about thinigs done in Last Call?

Guus: we can close the comments by internalization group
... Ivan proposed to write a page like the OWL page

<PatH> having a little trouble calling in, working on it.

sandro: in RDF, documents are pretty much self standing

<gkellogg> Turtle, TriG, and N-Triples would seem to be more closely related.

Guus: let us archive all comments being done since CR

<gavinc_> Yeah, my thoughts as well gkellogg

<gavinc_> given I have to update all three of those

<ivan> ivan, unmute me

gavinc_: I'll finish a page about the comments
... we have to publish the test cases

<AndyS> +1 to gkellogg -- and NQuads.

sandro: they should be linked from the document

<gkellogg> Conformance Report: https://dvcs.w3.org/hg/rdf/raw-file/default/rdf-turtle/reports/index.html

<PatH> looks like I am going to have to be restricted to IRC until my phone carrier comes back :-(
...: and we have to list the implementations

<pfps> shouldn't we note this error and fix it at REC?

AndyS: their could be a formal publication of the test suite
... W3C would use the test suite licence

(sorry did not get the end)

<sandro> google brings me to http://www.w3.org/2011/rdf-wg/wiki/Turtle_Test_Suite

<AndyS> http://www.w3.org/Consortium/Legal/2008/04-testsuite-license.html

AndyS: they are not complaininng of tests suite licence, but they complain about the Apacche Licence attached to it
... I could change this as a copywriter

<gavinc_> I'd say the main issue is the lack of publication of the test suite

sandro: the page about test suite should have link to the suite
... I can update the submission to point to the the suite

<Guus> http://dvcs.w3.org/hg/rdf/file/default/rdf-turtle/tests-ttl

Guus: in the extension request the link to test suite was the one posted

<gkellogg> https://dvcs.w3.org/hg/rdf/raw-file/default/rdf-turtle/reports/index.html

Guus: who would like to take an action to do this

gavinc: I can do this
... I can also resolve the licence issue
... we can set up a mercurial directory and put a tag there

AndyS: sandro, could you check the W3C process for the test suite

<gkellogg> List of dajobe's current Turtle tests, including test-31 through test-38: https://github.com/dajobe/raptor/tree/master/tests/turtle

<sandro> ACTION: sandro to learn about the w3c test suite license [recorded in http://www.w3.org/2013/02/27-rdf-wg-minutes.html#action01]

<trackbot> Created ACTION-232 - Learn about the w3c test suite license [on Sandro Hawke - due 2013-03-06].

<Guus> ACTION Gavin to publish the consolidated test suite

<trackbot> Created ACTION-233 - Publish the consolidated test suite [on Gavin Carothers - due 2013-03-06].

gavinc: all tests are under W3C license and 3-clause BSD licence

<gavinc> http://www.w3.org/2004/10/27-testcases

<AndyS> ??? == W3C test suite license

<gavinc> https://github.com/dajobe/raptor/blob/master/tests/turtle/test-30.ttl

Semantics

<gavinc> btw #turtle exists ;)

<AndyS> gregg - there was renumbering old 30 is new 27 and is there

Guus: there are several emails on the first editor's draft for semantics
... from pfps and Path

<gkellogg> andys: cool, thanks

<AndyS> gregg - blame automated test suite writing.

PatH: I think all the issues can be resolved wihtout spending much telecon time

pfps: we have to resovle the issues on ill-typed literals do not denote anymore

<pfps> http://lists.w3.org/Archives/Public/public-rdf-wg/2013Feb/0233.html

PatH: it's a substantial change to semantics and made in reaction to Richard's request

<ericP> oops, looks like i missed the test suite topic

<ericP> can anyone confirm/deny that?

PatH: who believe that a graph that has ill-typed literals should not be consistent
... the proposal makes all triples with an ill-typed literal false

<pfps> this change has been discussed extensively in the past, as well

PatH: I haven't find arguments really against it

<Guus> PROPOSE: I propose closing Issue 109 as described by Pat back in November in http://lists.w3.org/Archives/Public/public-rdf-wg/2012Nov/0195.html The proposal is, roughly, to make ill-typed literals not denote anything, which (due to the very picky details of the wording of the rest of the semantics) means that any triple with an ill-typed literal is false (and not ill-typed itself, which you might have thought).

<Guus> RESOLVED: propose closing Issue 109 as described by Pat back in November in http://lists.w3.org/Archives/Public/public-rdf-wg/2012Nov/0195.html The proposal is, roughly, to make ill-typed literals not denote anything, which (due to the very picky details of the wording of the rest of the semantics) means that any triple with an ill-typed literal is false (and not ill-typed itself, which you might have thought).

pfps: which datatypes are required in RDF implementation

<gavinc> +1 to RDF XMLLiteral being optional... I swear we resolved that?

<sandro> +1 I think so, too.

<gavinc> ... are you SURE we don't?

pfps: in particular XMLLiteral?

<gavinc> http://lists.w3.org/Archives/Public/public-rdf-wg/2012May/0198.html

<sandro> issue-13?

<trackbot> ISSUE-13 -- Review RDF XML Literals -- closed

<trackbot> http://www.w3.org/2011/rdf-wg/track/issues/13

pfps: can someone fix the "list of resolutions"

<gavinc> http://www.w3.org/2011/rdf-wg/track/issues/closed is a good place to start looking for resolutions :)

gavinc: HTML is optional too (ISSUE 33)

<gavinc> http://www.w3.org/2011/rdf-wg/track/issues/63

pfps the last issue is rdf:langString

PatH: I think the idea was a datatype with empty lexical-to-value mapping

<gavinc> Also, see http://lists.w3.org/Archives/Public/public-rdf-wg/2012Nov/0071.html

PatH: the goal is to have a type for all literals but not force rdf:langString to be a proper datatype

pfps: this should be fixed in Concepts

<gavinc> This is related to ISSUE-94

<gavinc> ISSUE-94?

<trackbot> ISSUE-94 -- Definition of literals does not include language-tagged strings properly -- closed

<trackbot> http://www.w3.org/2011/rdf-wg/track/issues/94

pfps: everything else in the semantics can be seen just as bugs
... it just requires minor edits to make it a FPWD

Guus: <can't hear>

<Guus> reviews can be done befpre html edits

<Guus> review volunteers? at least two needed

<pfps> can't be me

<pfps> I suggest Richard, even though he is not on the call - he cares about this

Guus: we need reviewers for the document, even before the edits

AZ: I can review it

pfps: I would like Richard to do it

<Guus> ACTION Guus to ask Richard to review Semantics

<trackbot> Created ACTION-234 - Ask Richard to review Semantics [on Guus Schreiber - due 2013-03-06].

PatH: there is a section that is missing about the inference rules

<pfps> the inference rules are informative, not normative

ivan: what's going on with the rules?
... in which document do they go

PatH: we can put the rules in an informative section in Semantics

<pfps> I vote for fewer documents

<pfps> why are the rules needed for concepts?

ACTION AZ to review RDF 1.1 Semantics

<trackbot> Created ACTION-235 - Review RDF 1.1 Semantics [on Antoine Zimmermann - due 2013-03-06].

Guus: we really need to go to LC for Concepts
... for this we need a FPWD for Semantics

ivan: our extension request said we would have Concepts in LC by 1st march

PatH: I can do the changes before next telecon

Guus: in the mean time we can talk about Concepts to prepare it for LC

<Guus> Reviewing period Semantics draft: 6-13 Mar

PatH: there is a debate about D-entailemnt whether D should be seen as a datatype map
... I see a solution that requires a small change to RDF Concepts

Guus: let us get this to the agenda of next week

pfps: I believe Pat's solution is not viable

PatH: I know how to fix this, I have to make it more precise

+1 pfps

<pfps> my problem is with a normative part of RDF Semantics referring to "web conventions"

Concepts

Guus: there is an issue on bnode definition

PatH: Concepts sould define the notion of scope
... scope of bnodes

<people looking in the ML archives>

<Guus> ACTION Guus put spec of scope bnodes in Concepts on agenda for 6 Mar

<trackbot> Created ACTION-236 - Put spec of scope bnodes in Concepts on agenda for 6 Mar [on Guus Schreiber - due 2013-03-06].

<pfps> I can review Concepts, but I will reiterate my concerns that have not yet been addressed.

Guus: we need reviewers for the LC draft

<pfps> There has been push back on some of them.

I can review too, to be sure my concerns have been addressed

<PatH> i can review concepts.

<SteveH> I'll be on vacation

<Guus> Peter and Ted are reviewer candidates

JSON-LD

Guus: we must find reviewers for this one too

<Guus> http://lists.w3.org/Archives/Public/public-rdf-wg/2013Feb/0189.html

PatH: I'll volunteer

sandro: I'll volunteer too

PatH: in fact, if it's now, I'll have to withdraw sorry

Guus: let us ask AndyS if he'd like to revieww it

<Guus> ACTION Guus to ask Andy to review JSPN-LD syntax doc

<trackbot> Created ACTION-237 - Ask Andy to review JSON-LD syntax doc [on Guus Schreiber - due 2013-03-06].

gkellogg: we have work to do on the API

bye

<markus> bye

<Guus> trackbot, end meeting
