16:14:14 <jcheney> ivan: what would extension mean for prov-n?
16:14:40 <Luc> you could write an xml schema that extends prov-xml schema (but this is not recommendation track)
16:14:40 <jcheney> pgroth: no results for vocabulary usage

16:17:21 <pgroth> [4:06pm]
16:18:21 <jcheney> zakim, who is noisy
16:18:21 <Zakim> I don't understand 'who is noisy', jcheney
16:18:23 <jcheney> zakim, who is noisy?
16:18:33 <Zakim> jcheney, listening for 10 seconds I heard sound from the following: ??P7 (4%), ??P33 (55%), Ivan (48%)
16:18:44 <jcheney> zakim, mute ??P33
16:18:44 <Zakim> ??P33 should now be muted
16:19:16 <jcheney> @ivan: could you make a screenshot of results and people can look at it off-line?
16:19:22 <Luc> q+
16:20:11 <jcheney> luc: we have 4 impls that write Entity and 5 that read / write Entity
16:20:11 <pgroth> yeah that's correct
16:20:56 <jcheney> ivan: then averages are meaningful: 4.56 is good
16:21:38 <jcheney> pgroth: for entity, agent we're fine
16:22:09 <jcheney> luc: 6 say no support for invalidation, 1 r/o, 2 r/2.  can we assume one reads what the other has written?
16:22:30 <jcheney> pgroth: would be good to see the actual people, so we can check this
16:23:15 <jcheney> pgroth: would like to make this public/group readable, and see where there are gaps
16:23:19 <pgroth> ack luc
16:23:20 <pgroth> q?
16:23:26 <jcheney> ivan: sounds reasonable
16:23:36 <Luc> q+
16:24:07 <jcheney> luc: just after averages table there are details, but only for two responses - why?
16:24:19 <Dong> that's what I see as well
16:24:56 <jcheney> ivan: can see all 9 rows
16:25:04 <jcheney> ... with all responses

16:33:59 <jcheney> ... deadline for review is thursday next week
16:34:19 <pgroth> Topic: Prov-o encoding constraints
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
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?
17:01:20 <jcheney> Luc: who will do test cases for other specifications?
17:01:24 <jcheney> pgroth: will do that
17:01:39 <jcheney> pgroth: goal do send for approval by wg on monday
17:01:46 <jcheney> pgroth: goal to send for approval by wg on monday
17:01:52 <jcheney> ... so we can send back on tuesday
17:01:54 <pgroth> q?
17:02:42 <jcheney> pgroth: seems uncontroversial so hopefully we can approve over mailing list
17:02:47 <jcheney> ... or at least try
17:02:59 <Dong> Monday is fine for my part
