<ChrisW> MInutes for June 23: http://www.w3.org/2009/06/23-rif-minutes.html

<ChrisW> PROPOSED: accept June 23 meeting minutes

<josb> Hey, that was my birthday!

<ChrisW> RESOLVED: accept June 23 meeting minutes

<ChrisW> http://www.w3.org/2009/08/25-rif-minutes.html

<ChrisW> RESOLVED: accept Aug 25 meeting minutes

<ChrisW> ACTION: leora update Sept 1 minutes [recorded in http://www.w3.org/2009/09/15-rif-minutes.html#action01]

<trackbot> Created ACTION-910 - Update Sept 1 minutes [on Leora Morgenstern - due 2009-09-22].

Liason

ChrisW: Sandro, update on OWL?

Sandro: RIF and OWL 2 both use xsd 1.1, xsd 1.1 looks like won't get out of CR until Jan next year
... this is a problem and we might have found an acceptable compromise:
...OWL will refer normatively to xsd 1.0 as ammeded by 1.1, and until such time as 1.1 become a recommendation any features of OWL that depend on it are optional

ChrisW: Will those items be called out explictly?

Sandro: No

ChrisW: Is it OK for RIF to go to PR if xsd 1.1 is in PR?

Sandro: Yes
... above plan with respect to to OWL should work for RIF too

Christian: Sandro, did you say we are not likely to go to rec before January?

Sandro: Yes, but it could likely be sooner also

ChrisW: We still plan to leave the CR deadline where we originally set it -- even though the beginning was pushed back a week
... ....it's near the end of October, and so four weeks is reasonable
... if we don't get the required implementations, we'll have to extend

Sandro: We use xpath heavily, so xpath people may have comments on the way we are using them

ChrisW: He should upload them and we'll review them

<AxelPolleres> http://lists.w3.org/Archives/Public/public-rif-wg/2009Sep/0039.html on action-733

CR Status update

ChrisW: We had a slight snafu, forgot to send email about CR to the chairs mailing list

http://lists.w3.org/Archives/Public/public-rif-wg/2009Sep/0040.html

ChrisW: We've now asked if they could review/respond within the week

Christian: There was a new public comment, what shall we do about it?

<AxelPolleres> http://lists.w3.org/Archives/Public/public-rif-comments/2009Sep/0003.html

AxelP: That comment is about an ambiguity in our grammar because we allow unicode strings in some places where I think we shouldn't

<AxelPolleres> http://lists.w3.org/Archives/Public/public-rif-wg/2009Aug/0003.html

<AxelPolleres> http://www.w3.org/TR/rdf-sparql-query/#rPN_PREFIX

<AxelPolleres> http://www.w3.org/TR/rdf-sparql-query/#rPN_LOCAL

AxelP: I think for variables, prefixes, etc, we should have more constrained productions (as in sparql)
... in the PS

ChrisW: Should we fix this?

AxelP: Yes, I think we need to

<AxelPolleres> Name ::= UNICODESTRING

<AxelPolleres> Var ::= '?' UNICODESTRING

AxelP: He is particularly complaining about the above 2 productions
... I think we should make them more constrained

ChrisW: Who should make this change?

<AxelPolleres> http://www.w3.org/2005/rules/wiki/DTB#Shortcuts_for_Constants_in_RIF.27s_Presentation_Syntax

<AxelPolleres> # LocalName, cf. http://www.w3.org/TR/2006/REC-xml-names11-20060816/#NT-LocalPart

AxelP: Is it acceptable in our spec to just point to productions in other specs?
... (as DTB currently does)

Harold: I think Axel's approach is good

Sandro: Since this only affects the PS, names will still be unrestricted in XML, right?

<ChrisW> ACTION: axel to replace name, var, and dialect by ncname in all BNF grammars [recorded in http://www.w3.org/2009/09/15-rif-minutes.html#action05]

<trackbot> Created ACTION-914 - Replace name, var, and dialect by ncname in all BNF grammars [on Axel Polleres - due 2009-09-22].

<AxelPolleres> http://lists.w3.org/Archives/Public/public-rif-wg/2009Aug/0002.html

AxelP: I just realized that there is a problem in DTB about prefix directives that MichaelK pointed out that I have not done yet

<AxelPolleres> Axel to put IRIs within <...> in the Prefix directive

<AxelPolleres> ACTION: Axel to put IRIs within <...> in the Prefix directive in DTB [recorded in http://www.w3.org/2009/09/15-rif-minutes.html#action10]

<trackbot> Created ACTION-919 - Put IRIs within <...> in the Prefix directive in DTB [on Axel Polleres - due 2009-09-22].

Axel: And another item that might need discussion: see email above

<AxelPolleres> http://www.w3.org/2005/rules/wiki/index.php?title=DTB&diff=10665&oldid=10495

Axel: Above diff shows my proposed change

ChrisW: How to we handle variable- arity predicates in DTB?
... concat, for example

AxelP: Xpath version of concat uses a sequence but xpath version of string-join does not
... I don't have a strong opinion on what fix we should adopt; I chose the simplest one

ChrisW: Michael expressed an opinion about this but he isn't here
... AxelP, could you respond to MichaelK's email saying we discussed it in the telecon and describing the approach you took

AxelP: Sandro, would you review the list functions if I rework them to make them uniform with other functions in DTB
... I'm talking about writing the semantics in terms of mappings

<ChrisW> ACTION: axel to look at informal list mappings [recorded in http://www.w3.org/2009/09/15-rif-minutes.html#action11]

<trackbot> Created ACTION-920 - Look at informal list mappings [on Axel Polleres - due 2009-09-22].

RIF/XML

Christian: I responded to DaveR's and GaryH's reviews, and I think there is a fair amount of work left to implement their comments
... so I don't think we can publish in this round
... when would be the next opportunity to publish the RIF XML-DATA document?

ChrisW: Any Tuesday or Thurs we can publish. When do you think you could have it ready?

Christian: I could update it by next week, but would DaveR and GaryH be able to rereview it then?
... if I have it ready next week, and GaryH and DaveR review in a week, we could publish in 2 weeks

GaryH: Yes, I can review it

Test Cases

<Harold> Sandro, http://www.w3.org/TR/ seems to be a huge area of W3C documents.

<Harold> ... including Recently Published Working Drafts

<sandro> level of indirection: http://www.w3.org/2009/owl-test-cases

<sandro> owl 1 test cases: http://www.w3.org/TR/owl-test/

<Harold> (and Recently Published Group Notes).

<sandro> owl 2 test document: http://www.w3.org/TR/owl2-conformance/

ChrisW: It may be a good idea to actually include the test cases in the text of the test document. I'd like to see a version of that, to see what it looks like.

Harold: The test document shouldn't point to a wiki (the test cases listing page) because the wiki isn't permanent

ChrisW: Need two reviewers for test cases
