It was determined that the surveys are in the wrong group within WBS so that only W3C Team members (and not prov group members) can see the full results. Paul was actioned to remind Ivan to ask the W3C Systems team if they could move the surveys. Paul was actioned to go through the current results of the questionnaire and see where there are gaps. Broadly, it seems there are enough submissions in terms of usage but there are concerns about demonstrating interoperability between pairs of systems. Dong was asked to update the test case process document to refer to the WBS survey and not email. 16:07:28 <jcheney> ...stephan working on xml namespace 16:07:46 <jcheney> ... was hoping for update from stephan (who gets the emails) 16:07:59 <smiles> smiles has joined #prov 16:08:05 <jcheney> ... would like to see how to make a report from survey results 16:08:12 <Luc> 10 implementations, 5 vocab extensions 16:08:15 <Zakim> +??P7 16:08:44 <jcheney> ...

"last call" before prov-aq released as ready for implementation 16:33:52 <pgroth> q? 16:33:59 <jcheney> ... deadline for review is thursday next week 16:34:19 <pgroth> Topic: Prov-o encoding constraints <pgroth> Summary: The group went over ISSUE-612 on encoding constraints in OWL. Two issues were identified: 1) that Kerry though that wasDerivedFrom was transitive, which it is not. 2) Whether prov-o should include encodings of constraints. For 1) Luc agreed to formulate a response to kerry. For 2) the group agreed that that encoding owl constraints was not part of prov-o and that it was an implementation. It was also agreed that this should be signposted in the various documents. Paul agreed to formulate a response. 16:34:26 <pgroth> http://www.w3.org/2011/prov/track/issues/612 16:34:46 <jcheney> pgroth: comments from two implementors working with prov-o and constraints 16:35:08 <jcheney> ... looking for constraints implementable in OWL to be part of prov-o 16:35:40 <jcheney> ... this was discussed and resolved not to do this earlier, but this could be an implementation technique 16:35:46 <Luc> q+ 16:35:50 <jcheney> ... how to address? 16:36:22 <jcheney> Luc: no consensus for derivation to be transitive; we voted against this and it is not a constraint in the document. 16:37:01 <pgroth> ack luc 16:37:15 <jcheney> luc: should review & approve responses, but would be good to tell them this specific point 16:37:34 <ivan> q+ 16:37:37 <Luc> action: Luc to write a response to Kerry why derivation is not transitive 16:37:37 <trackbot> Created ACTION-160 - Write a response to Kerry why derivation is not transitive [on Luc Moreau - due 2013-01-17]. 16:37:41 <pgroth> ack Ivan 16:38:01 <jcheney> ivan: what is wrong with putting expressible constraints in separate document? 16:38:33 <jcheney> ... don't see a case for editing prov-o core document 16:39:06 <jcheney> pgroth: fine if people (in or out of wg) want to encode constraints, but not necessarily part of wg delierables 16:39:14 <jcheney> s/delierables/deliverables/ 16:39:27 <jcheney> ivan: if wg members do this, we can at least publish it somewhere 16:39:28 <pgroth> q? 16:39:42 <Luc> q+ 16:39:47 <pgroth> ack luc 16:40:07 <jcheney> Luc: need to respond to reviewers, along lines Paul gave 16:40:16 <jcheney> ... open questions whether some/all constraints implementable and how 16:40:52 <jcheney> ... wg decided to view this as an implementation issue, we can offer to gather experiences with this/axioms suggested by implementors 16:41:27 <jcheney> pgroth: sounds fine, but it seems to come up - should we say this in prov-o or constraints saying this? 16:42:11 <pgroth> q? 16:42:17 <jcheney> Luc: seems reasonable. not sure where. james? 16:43:58 <pgroth> q? 16:44:16 <jcheney> jcheney: could put disclaimer/explanation in constraints, maybe signpost elsewhere 16:44:39 <jcheney> pgroth: could say something in overview, prov-o also 16:45:10 <pgroth> action: pgroth to draft response on owl implementation of prov-constraints 16:45:11 <trackbot> Created ACTION-161 - Draft response on owl implementation of prov-constraints [on Paul Groth - due 2013-01-17]. 16:45:28 <pgroth> topic: Test cases response <pgroth> Summary: The group discussed issue 611 an in particular the issue with test cases. The group noted that the test cases should not be normative as these may change and be updated. In addition the group noted that if the test cases and the spec disagreed it would be hard to determine which was the tie breaker. Thus, there was consensus that the test cases were non-normative. Luc noted that the test cases can also be used as good examples of provenance and thus function as test cases for the two normative serialisations (prov-o, prov-n) . The group agreed to try to draft responses to all comments by Monday. Each part of issue 611 was divided up and assigned to a group member as documented on http://www.w3.org/2011/prov/wiki/ResponsesToPublicCommentsCR 16:45:36 <pgroth> http://www.w3.org/2011/prov/track/issues/611 16:46:34 <jcheney> pgroth: james responded to questions about constraints; this seems fine as response to that part if wg can endorse 16:46:44 <jcheney> ... also asked about prov-constraints test cases 16:46:54 <jcheney> ... should they be part of spec? 16:47:07 <pgroth> We 16:47:07 <pgroth> would like to see test suites for the other operational parts of PROV, 16:47:07 <pgroth> in particular for testing inferences separate from validation. 16:47:26 <jcheney> ... in particular, in a normative place. 16:47:39 <jcheney> ... and would like further test cases for other documents 16:47:43 <pgroth> q? 16:47:45 <jcheney> ... how should we respond 16:47:54 <jcheney> ivan: why do they want it in normative spec? 16:48:11 <jcheney> pgroth: if normative, then better interoperability (they say) 16:48:42 <jcheney> ivan: that's a matter of opinion. otoh, if list of test cases become normative, cannot extend them later, or would have normative & non-normative tests 16:49:00 <jcheney> ... if test suite is non-normative, then we have capability to add new tests even when docs published 16:49:14 <jcheney> ... had this in rdfa wg 16:49:23 <Dong> q+ 16:49:46 <jcheney> ... discrepancies between implementations arose, which were addressed through additional tests 16:49:52 <Dong> Zakim, unmute me 16:49:52 <Zakim> Dong should no longer be muted 16:49:52 <pgroth> q? 16:50:26 <jcheney> Dong: if we move test cases into normative, are we saying that an impl that passes all test cases are compliant? We would have two definitions 16:50:34 <jcheney> ... test cases and original spec 16:50:44 <jcheney> ... cannot be sure that test cases cover all constraints. 16:50:59 <jcheney> ... would provide false sense of ciompliance 16:51:00 <pgroth> q? 16:51:03 <pgroth> ack Dong 16:51:06 <Dong> Zakim, mute me 16:51:06 <Zakim> Dong should now be muted 16:51:06 <Luc> q+ 16:51:08 <jcheney> s/ciompliance/compliance 16:51:33 <jcheney> Luc: other issue is that we don't have formal mappings / equivalence between the serializations 16:51:39 <pgroth> ack Luc 16:51:50 <jcheney> ... it could be that some test cases would work in prov-n and not rdf or vice versa. 16:52:07 <jcheney> ... not in favor of normative test cases 16:52:40 <jcheney> ... do we need other test cases for other specs? 16:52:49 <jcheney> (previous line is pgroth) 16:52:57 <jcheney> pgroth: do we need other test cases for other specs? 16:52:59 <pgroth> q? 16:53:04 <Luc> q+ 16:53:23 <pgroth> ack Luc 16:54:08 <jcheney> Luc: the test suite contains typical examples expressed in prov-n, prov-o. what else could we do beyond having weird examples to exercise syntax? 16:54:17 <jcheney> ... more interesting to have useful provenance examples 16:54:49 <jcheney> pgroth: test cases provide example repository, can be used to test compliance with other specs 16:54:55 <pgroth> q? 16:55:03 <Luc> this was a suggestion from the SW coordination group that we have a set of useful provenance examples 16:55:22 <Luc> q+ 16:55:28 <jcheney> pgroth: we seem to have outline of response 16:55:49 <jcheney> Luc: important to try to provide responses promptly because they are trying to implement and may be waiting before submitting reports 16:56:10 <Luc> i have updated page http://www.w3.org/2011/prov/wiki/ResponsesToPublicCommentsCR 16:56:13 <Luc> q+ 16:56:36 <pgroth> ack Luc 16:56:43 <jcheney> pgroth: Luc will do response to Kerry, Paul will respond to general question need one for test cases and their comments on constraints 16:57:19 <jcheney> Luc: created page for responses 16:58:04 <jcheney> ... suggest we assign people to address these 16:58:53 <jcheney> pgroth: prov-o (611) essentially same as 612 about encoding constraints in owl, paul will do these 16:59:22 <jcheney> ... jcheney will do 611 (constraints) 17:00:06 <Dong> ok 17:00:09 <jcheney> ... 611 (normative test cases) - Dong 17:00:32 <jcheney> ... can we do this by monday?
