15:09:43 <Luc> topic: Prov-o Issues
<luc>Summary: Outstanding issues were reviewed. Group answer to ISSUE-491 remains to be written; Luc will contact Stian about it.  ISSUE-522 is the only technical issue remaining to be addressed. Tim will draft a response and share it with the group, with a view to respond to the reviewer early next week. In response to ISSUE-522, Luc also updated the wording in prov-dm.  All outstanding issues are purely editorial and the team believes the document will be ready for the face to face meeting.

15:34:32 <Luc> q?
15:34:42 <Luc> topic: prov-n issues
<Luc>Summary: In response to Ivan's feedback, the group discussed the scope of prefix declarations in prov-n. It was suggested that prefixes declared in a document should also be visible in bundles (unless they have been redeclared).   Ivan confirmed that this was not a design change, but a syntactic sugar change.  The group endorsed the proposal (and issue-589 was raised to that effect). Graham was also satisfied with the changes to the mime type application. It is planned to implement the new issue shortly and complete the document ahead of the meeting.
15:34:58 <Luc> http://www.w3.org/2011/prov/track/products/11
15:35:04 <tlebo> luc: only 2 issues
15:35:39 <tlebo> ... ivan was fine, but we want to confirm...
15:36:05 <tlebo> ... namespace declarations and bundles. bundles do not "inherit" prefixes.
15:36:32 <Luc> q?
15:36:32 <tlebo> q+
15:36:33 <GK> q+
15:36:55 <GK> q-
15:37:19 <Luc> ack tl
15:37:26 <tlebo> @gk probably would have stated it better...
15:38:02 <tlebo> gk: same point as Tim, you were responding to URIs of entities
15:38:11 <tlebo> luc: do we need to revise?
15:38:23 <jcheney> Currently says: "The scope of a namespace declaration directly occurring in a document is the document itself, excluding the bundles it may contain."
15:38:25 <tlebo> ... one benefit is that bundles are totally distinct.
15:38:52 <jcheney> This forces you to repeat prefixes in common cases, including many natural-looking examples in prov-dm
15:39:00 <Luc> q?
15:39:40 <Luc> q?
15:40:04 <Luc> q?

15:40:15 <jcheney> q+
15:40:33 <tlebo_> tlebo_ has joined #prov
15:40:53 <GK> I was saying that I thought the current design is maybe sub-optimal for human use, but not fatally flawed.
15:41:04 <tlebo_> tlebo_ has joined #prov
15:41:21 <Luc> q?
15:41:23 <smiles> jcheney: Missed original change to excluding namespaces in top-level bundle; changing the scope to include the namespaces from top-level might not break anything?
15:41:54 <smiles> Luc: Would need to get advice on whether this is only an editorial change
15:42:08 <smiles> ... How strongly do you feel about this?
15:42:55 <tlebo> tlebo has joined #prov
15:43:01 <smiles> jcheney: There are situations where it is useful to think of bundles as independent and copy-paste without worrying about top-level, but using namespace without repeating declaration throughout a document is common
15:43:45 <smiles> ... Natural expectation is that if you state something then embedded scopes would include that thing
15:44:05 <tlebo> FWIW, Turtle and Trig permits the prefixes to be defined once and used in any of many "bundle".
15:44:06 <smiles> Luc: Are we willing to go ahead with change even if it is not just editoral, i.e. back to LC
15:44:26 <tlebo> This is not worth going back to Last Call for.
15:44:37 <smiles> jcheney: It is something that people will anyway notice and complain about in implementation
15:44:44 <GK> Maybe ask Ivan if this would need to redo last call.  It seems a small change, albeit technical.
15:44:56 <ivan> if I may, just on IRC...
15:45:02 <ivan> this is not a design change
15:45:09 <Luc> thanks ivan
15:45:18 <ivan> this is a change in a syntactic sugar
15:45:25 <Luc> ok
15:45:35 <ivan> it would influence implementations, but that is not the issue for LC
15:45:53 <smiles> Luc: Given the above, it would be good to know the WG's preference
15:46:05 <Luc> show of hand: allow scope of prefix declarations
15:46:40 <tlebo> +1 because that's how it's done in Turtle/Trig, -1 b/c PROV-N is for examples in Recs :-)
15:46:59 <smiles> satya: Please clarify question
15:47:13 <GK> +0.5 to top-level namespaces visible in contained bundles in PROV-N (next question: can they be redefined in inner bundles?)
15:47:22 <jcheney> See namespace scope rules in http://dvcs.w3.org/hg/prov/raw-file/default/model/prov-n.html#expression-NamespaceDeclaration
15:47:23 <hook_> hook_ has joined #prov
15:47:44 <smiles> Luc: Currently in PROV-N, when declaring prefix at top level and want to re-use in nested bundle, have to redeclare prefix in bundle
15:47:48 <jcheney> Currently, this is illegal:
15:47:53 <jcheney> document  prefix ex <http://example.org/>  bundle ex:b1     entity(ex:e1, ...someattr1...)     entity(ex:e1, ...someattr2...)  endBundle endDocument
15:48:05 <jcheney> because ex is not re-declared inside the bundle
15:49:02 <smiles> Luc: @GK, yes, prefixes could be redefined in inner bundles
15:49:24 <jcheney> I http://dvcs.w3.org/hg/prov/raw-file/default/model/prov-n.html#expression-NamespaceDeclaration
15:49:42 <smiles> jcheney: Suggest just changing sentence in PROV-N from "excluding the bundles it may contain" to "including..."
15:50:07 <tlebo> reusing throughout and allowing redefinition in inner bundles would make it much more useful for humans to read and write.
15:50:13 <smiles> ... People have been writing examples that assume the proposed change without realising
15:50:14 <GK> Seems to me easier to change the text than the examples
15:50:16 <Luc> proposed: change  scope of prefix declaration so that it includes bundles

15:52:51 <smiles> Luc: Everything else covered in PROV-N aside from two issues above
15:52:57 <Luc> topic: PROV-DM issues
<Luc>Summary: the outstanding issue in prov-dm is related to mention (issue-475). A response was circulated during the week. The proposal is to keep the feature marked at risk, and as indicated in the document, make a decision on its suitability based on implementer's feedback.  A vote is to be carried out by email (deadline next Tuesday) in time to respond to the reviewer.
15:53:17 <Luc> http://www.w3.org/2011/prov/track/products/2

15:56:04 <smiles> Luc: Conclusion of my response is that we want feedback from implementers
15:56:17 <smiles> ... As we exit CR phase, can look at suitability
15:56:36 <Luc> q?
15:56:46 <smiles> Luc: Any feedback now?
15:56:50 <tlebo> +1 to keep it in, marked as at risk.

15:58:26 <smiles> +1 to vote by email
15:58:27 <zednik> I like vote by email
15:58:36 <jcheney> +1 email
15:58:38 <tlebo> vote by email seems to be the resounding response. I know I could use a bit more time to work through it entirely.
15:59:18 <smiles> Luc: Will send an email with a deadline
15:59:24 <Luc> topic: prov-xml
<luc>Summary: The editors of the prov-xml document have produced a draft of the specification and are now seeking feedback. Luc and James have volunteered to review the document. Other reviewers would be appreciated. The key question is to decide whether the document is ready for release as a fpwd, synchronised with the CR release. It was discussed whether there was time to update the primer with xml examples. The prov-xml team will draft the example in full in xml and will share it with Simon.
16:00:06 <Zakim> -Satya_Sahoo
16:00:17 <smiles> zednik: We have made significant changes to XML note, including table of features mapping  PROV-DM to XSD, plus examples with excerpts of schema
16:00:40 <zednik> http://dvcs.w3.org/hg/prov/raw-file/1816251fd592/xml/prov-xml.html
16:00:46 <smiles> ... Now looking for feedback on the HTML
16:01:48 <smiles> Luc: Thanks. There is an opportunity to release first WD of this doc with CRs of other specs. Will it be ready?
16:02:23 <smiles> ... Next week we would take a vote, discuss with W3C management to publish CRs, so two weeks for XML document before publishing
16:02:39 <hook> hook has joined #prov
16:02:52 <smiles> zednik: Probably get ready in two weeks, but need to address WG comments, ensure there is no gaps (e.g. bundles)

16:04:03 <smiles> Luc: Feedback in time for F2F
16:04:19 <smiles> ... Question for reviewers: Can we release this document as a FPWD
16:05:06 <smiles> Luc: Intent to include XML in primer. Feasible to include for release?
16:05:51 <smiles> smiles: For primer, if given XML fragments, then quick job to add
16:06:07 <smiles> zednik: Possibly, but need to look at examples in primer
16:06:20 <GK> @luc - the text/provenance-notation MIME registration revisions look fine to me at http://dvcs.w3.org/hg/prov/raw-file/default/model/prov-n.html#media-type
16:06:24 <hook> might need to check latest fragments for bundles per recent updates
