<pgroth> Summary: The group converged on several issues with respect to PROV-XML. The group agreed to adopt qnames for identifiers in -xml as it seemed to be the most natural for xml and had the least number of issues. The group agreed to have an ordering of attributes in prov-xml in order to facilitate usage in tools, in particular, jaxb. It was also suggested to create an FAQ entry/page around the use of PROV-XML with jaxb giving examples etc.. A discussion was had around the current organization of the schemas. After explanation, the group was satisfied with the current structure. The editors were encouraged to get the changes done so that a review can happen before a PR release.

Initially, the group didn't want to change the schema and work via JAXB mapping/etc. But those options seemed too complex, so Curt and I worked on adding ordering yesterday 16:14:44 <Dong> Dong has joined #prov 16:15:16 <Curt> q+ 16:15:20 <TomDN> ... So it's reasonable to proceed with ordered attributes 16:15:44 <TomDN> Curt: I think it's cleaner and more elegant 16:16:05 <pgroth> ack curt 16:16:16 <pgroth> Proposed: use order attributes in prov-xml 16:16:17 <TomDN> ...

There's still some discussion between Luc and Stian on the mailinglist. 16:19:39 <TomDN> Luc: I don't think there is consensus.

There are schema's out there describing provenance, and we want to be able to include these in PROV-XML 16:20:51 <TomDN> ... The proposed solution with the substitution group seems to require changes to legacy schema's. 16:20:55 <CraigTrim> Zakim, aaaa is me 16:20:55 <Zakim> +CraigTrim; got it 16:21:01 <TomDN> ... and this is undesirable. 16:21:32 <TomDN> zednik: The substitution groups are meant to include elements that are in the provenance namespace. 16:21:44 <TomDN> ... for everything else we still have xs:any 16:21:56 <pgroth> q? 16:22:03 <TomDN> ... so you can use elements that don't use the prov: namespace 16:22:22 <pgroth> q? 16:22:24 <TomDN> Luc: Ok, thank you for the clarification. 16:22:24 <Luc> q+ 16:22:30 <pgroth> ack Luc 16:22:47 <TomDN> Luc: So, as we were talking about JAXB, does this also work with JAXB? 16:22:56 <TomDN> zednik: yes, the current version works with JAXB. 16:23:04 <pgroth> cool 16:24:22 <TomDN> Luc: So dictionary and mention work as well? 16:24:28 <TomDN> zednik: yes. 16:25:13 <TomDN> Luc: Why do we need a sequence of choice and abstract elements in the document element? 16:25:25 <TomDN> zednik: I think the latest schema might fix that 16:25:29 <TomDN> ... will doublecheck. 16:26:09 <TomDN> pgroth: So are you ok with the current solution, Luc? 16:26:20 <TomDN> Luc: Yes, it seems it's ok now. 16:26:40 <TomDN> pgroth: Seems the issue is resolved now then. 16:27:01 <TomDN> pgroth: To wrap-up, is there anything outstanding now? 16:27:08 <TomDN> zednik: just fixing up the text. 16:27:30 <Luc> q+ 16:27:36 <TomDN> pgroth: Once the text is updated, we can go to internal review. 16:27:37 <pgroth> ack Luc 16:28:07 <TomDN> Luc: We need to make sure to get the PROV-XML reviews back in time for the PR pulication then 16:28:10 <pgroth> Topic: Implementation Report <pgroth> Summary: A draft implementation report was presented. Timetables to PR were discussed. The following timetable was outlined: Review of Implementation Report by the WG week of Feb 11. WG Vote on move to PR at Feb 21 telcon. After that the goal would be to have publication date on March 12th (obviously, hoping that the W3C process goes smoothly). All documents including notes should be staged by March 5. We need to ensure proper review for notes by the WG by that time. 16:28:24 <TomDN> pgroth: Dong and I have been working on the report 16:28:31 <pgroth> https://dvcs.w3.org/hg/prov/raw-file/default/reports/prov-implementations.html 16:28:38 <TomDN> ... Dong did an impressive amount of work. 16:29:20 <TomDN> ... The report is almost done. Some small stuff remaining to do. 16:30:36 <TomDN> ... We'd like to send out the report for review on Monday, and set up the timetable for publication and going to the next stage. 16:31:28 <Luc> q+ 16:31:29 <TomDN> Ivan: Maybe we can get the votes in by email by the end of next week 16:31:38 <TomDN> ... since there is no telecon next week 16:32:20 <pgroth> ack Luc 16:32:24 <TomDN> Luc: It may be good to try and speed up the process. But we need to allow them to respond/revise. 16:32:30 <dgarijo> there is a vocabulary named Jun Zhao :O 16:32:32 <TomDN> ... after the review. 16:33:03 <Luc> + section 7 16:33:12 <TomDN> Ivan: It looks good. We still need something that says: we met the exit criteria and this is why. 16:33:57 <TomDN> ... We have a lot of implementations, 54, which is very impressive. 16:34:41 <pgroth> everybody keep your enthusiasm up :-) 16:35:10 <TomDN> pgroth: Once we say we want to go to PR, do we need the big long email again? 16:35:21 <TomDN> ivan: yes, just like we did with CR. 16:35:29 <TallTed> TallTed has joined #prov 16:35:31 <TomDN> ... I can help. 16:35:48 <Luc> is it time to think of a publication date, to finalize our documents? 16:36:20 <Luc> q+ 16:36:57 <TomDN> ivan: Am I correct that there is not that much editing left to be done? 16:37:06 <TomDN> pgroth: Just PROV-Constraints 16:37:13 <TomDN> jcheney: will do that tomorrow 16:37:24 <TomDN> ivan: excellent. 16:37:28 <pgroth> ack Luc 16:38:27 <TomDN> Luc: If we are going to vote by email, and the outcome it positive, we want to be ready for PR as soon as possible. So we need the URLs with the publication date. 16:39:22 <TomDN> Luc: So I suggest that Ivan starts the process to get the date agreed. 16:40:04 <TomDN> ivan: either March 7th or 12th 16:40:36 <TomDN> pgroth: I think we should aim for the 12th 16:40:47 <TomDN> ivan: yes, that seems without risk. 16:41:38 <SamCoppens> SamCoppens has joined #prov 16:43:56 <TomDN> Luc: so the url's? 16:44:31 <TomDN> ivan: I think it's safe that the editors start preparing the documents for 2013.03.12 as date 16:44:43 <Zakim> -[IPcaller.a] 16:45:50 <Luc> can we check all notes will be ready then? 16:45:52 <TomDN> pgroth: For health and safety reasons of half the chairs, we should ask the webmaster for the date :) 16:47:27 <TomDN> ivan: will do 16:47:59 <TomDN> ivan: Do note: what we send out for PR is the final document. So be sure to spellcheck etc. and be 100% sure 16:48:11 <TomDN> +q to ask if this also goes for the final notes 16:48:22 <tlebo> so, when are the PR drafts finalized? 16:48:25 <TomDN> Zakim, unmute me 16:48:25 <Zakim> TomDN should no longer be muted 16:48:27 <pgroth> ack TomDN 16:48:27 <Zakim> TomDN, you wanted to ask if this also goes for the final notes 16:48:28 <pgroth> 16:49:09 <TomDN> TomDN: Can we still touch the notes after we send out the PRs? 16:49:10 <dgarijo> ok! 16:49:25 <Luc> do we have time to review those that still need review? 16:49:26 <TomDN> pgroth: yes, but we'd like the final version of the notes on the 12th 16:49:36 <pgroth> action: paul to remind note editors about March 12 deadline 16:49:37 <trackbot> Created ACTION-164 - Remind note editors about March 12 deadline [on Paul Groth - due 2013-02-14]. 16:49:43 <TomDN> ...

So we need an appropriate amount of time. 16:53:19 <TomDN> ... Will we have enough time? 16:53:23 <satya> sorry, I have to leave 16:53:28 <TomDN> pgroth: We have 4 weeks to complete reviews 16:53:30 <Zakim> -Satya_Sahoo 16:54:02 <TomDN> ...
