5. XML syntax of Import

<csma> http://www.w3.org/2005/rules/wg/meeting/2009-04-16#resolution_7http://www.w3.org/2005/rules/wg/meeting/2009-04-16#resolution_7

Scribe's note: Resolution 7 reads:
In the XML syntax (for Core, BLD, PRD), the xml-schema type of both arguments to import is an anyURI -- NOT rif Const element(s).

See: http://www.w3.org/2005/rules/wg/meeting/2009-04-16#resolution_7

harold: seems to have misunderstood the resolution.
... does not support it.

<AdrianP> we could make locator a type tag "Locator"

<AdrianP> then we don't violate the syntax design principle of RIF

harold: I would have asked for a discussion of this point.

csma: is there anyone else who thinks the statement is ambiguous?

michael: the implications probably weren't understood.

csma: overturning the resolution on the argument that we didn't understand the implications is a dangerous precedent.

sandro: if true that we didn't understand some implication, that is a reason to re-open it. I don't know if that's the case here.

<StellaMitchell> re: ambiguous - when I first went back and read the resolution I misunderstood it - thought BLD was aligned with the decision

<AdrianP> I think it would be the only place where the role tag contains some content

<AdrianP> so we cannot omit role tags in the syntax

<ChrisW> +1 continue discussing

<AdrianP> +1

<StellaMitchell> +1 revisit

<Harold> +1

<mdean> +1

<sandro> +0.5 okay to talk about it more

+1

<MichaelKifer> +1

harold: I would like to write up the dilemma, send it in email, and we can then read it, and discuss it at the next telecon.

csma: Please put in email the explanation of the implication.

6. Implementations

csma: Have we received implementation reports?

<ChrisW> close action 945

<ChrisW> close action-945

<trackbot> ACTION-945 Put this discussion on the agenda for next time closed

<Harold> http://www.w3.org/2005/rules/wiki/Implementations

csma: we should have 6 BLD implementations (some are already available)
... and 3 PRD implementations (one from ilog)
... 1 SWC implementation, 2 Core implementations,
... for DTB, do we need one implementation of each built-in and datatype?

chris: exit criteria says we'll have two implementations of each built-in
... but they need not be independent

csma: We have one implementation of DTB, but it's just a syntax validator, which may not really count.
... Though at least it would pass all the syntax tests.

chris: must check fuxi and ontoprise regarding implementation of (??? SWC???)

[why? fuxi mentions OWL, but ontoprise just is listed for BLD ??]

mdean: should have something by the end of the month.

michael: same for me.

csma: at RULE-ML challenge, there was something that showed RIF compatibility (was showing translation to PRD among other things)
... May not count as a PRD implementation, because based on an old spec, but I encouraged them to post on wiki, and update.
... But this points to the possibility that there are other people who may be working on implementations.

<Harold> Re DTB implementations, I think we need just one implementation of each built-in, since the Java snippet implementing a built-in is modularly separated from the Java snippets implementing other built-ins. Also, its conformance to the DTB spec can be modularly tested. So everyone can just copy and paste the Java snippets into their own implementation.

Discussion on how close implementors are to implementations.

csma: Currently no test results from anyone but Gary. No idea on how conformant any of them are.

sandro: test results from jos de roo on DTB. Not in right format, but there are results.

<StellaMitchell> Jos De Roo's are not our test cases, are they?

csma: We'll add column on test results to implementation page.

<StellaMitchell> not just format, but they are different tests

Leora: Do we know if anyone is using our test cases, or their own?

action csma to send email to implementors asking for test results.

<trackbot> Created ACTION-947 - Send email to implementors asking for test results. [on Christian de Sainte Marie - due 2009-11-17].

csma: how to proceed on DTB: ask everyone which datatype and built-in they are doing?

sandro: no, ask which ones they are *not* doing.

csma: ask for specifics to ensure coverage of DTB

<StellaMitchell> maybe they should be split further

csma: will ask in my email for more specific results for DTB

<csma> next item

7. Test cases

gary: I have not seen a test case for list built ins.

sandro: test cases in spec, but not in test case suite

csma: test case on having list in slot?

<csma> http://www.w3.org/2005/rules/wiki/Assert

<StellaMitchell> Gary, the Assert* results are not in your results

<StellaMitchell> it seems like the group should follow its own "shoulds"

Problem, briefly: This test case should be in Core.

<StellaMitchell> why would we want to have a test case that illustrates bad practice?

<csma> PROPOSED: to approve http://www.w3.org/2005/rules/wiki/Assert with a note saying that this is not good practice (since it is translatable in COre, it should be in Core)

<Gary> +1

<csma> +1

<AdrianP> +1

<StellaMitchell> no

<csma> RESOLVED: to approve http://www.w3.org/2005/rules/wiki/Assert with a note saying that this is not good practice (since it is translatable in COre, it should be in Core)

<StellaMitchell> but I would be curious to hear the answer

<AdrianP> yes, will ad

<StellaMitchell> ok

<csma> http://www.w3.org/2005/rules/wiki/Retract

sandro: I would prefer not to combine print and retract; it is not the simplest retract case.

csma: makes sense to just add the end of the second rule to be an assert rather than a print.

sandro: otherwise, we'd have to have a new print test case, and a new type (input/output), etc.

<ChrisW> i need to go, sorry

sandro: I would add a second frame about John, and then make sure that is gone. Use a negative entailment test.

<sandro> ex:john[ex:name -> "Johnl"]

<sandro> Not-Entailed: ex:john[ex:name -> "John"]

<sandro> Non-Conclusion

<sandro> NegativeEntailmentTest

<StellaMitchell> do you mind if I put the PS of Assert into Core syntax, or do you actually want it in PRD syntax?

I want to point out: I cannot scribe past 12:35, so we probably want to wrap up.

action csma to modify retract case.

<trackbot> Created ACTION-948 - Modify retract case. [on Christian de Sainte Marie - due 2009-11-17].

csma: next telecon on nov 24
