16:04:41 <GK> Topic: Disseminating Working Drafts
<luc> Summary: We discussed ways of advertising and disseminating our working drafts. Paul will draft a blog overviewing all prov-wg documents. Luc will draft a blog explaining changes in prov-dm. Everybody is invited to share documents within their respective communities. The public-prov mailing list will be used for announcement, and the newly created public-prov-dev mailing list will focus on development issues.

16:27:19 <dgarijo> so I guess this is the list where we'll move our prov-o discussions.
16:27:32 <GK> Topic: Plan for Second Working Drafts (continued)
<luc>Summary: The editors of the prov-primer and prov-o documents discussed their plan for future working drafts. It was agreed that F2F2 is a good target to aim at, to release new versions of the documents synchronized with the current state of prov-dm.
16:28:31 <GK> SimonM: primer - 1st PWD should be out soon. Hopefully next week.
16:28:44 <GK> ... need to ensure compatibility with other documents.
16:29:02 <GK> ... aim to have improved version by F2F meeting
16:29:22 <Zakim> + +1.760.705.aaff
16:29:34 <GK> ... longer term, next release 6 months with everything up to date, and better content quality 
16:30:05 <GK> ... accessible to wide audience, libraries, bloggers, semantic web, etc. can use to get started
16:30:42 <GK> ... be clear what prov-dm means ontologically, how to integrate domain specific with prov-dm
16:31:31 <Luc> Can you confirm 6 months? See
16:31:35 <Luc> q?
16:31:39 <GK> Yolanda: have lots of comments about assertions and derivations: need to make distinction clear in primer.
16:32:27 <Luc> q?
16:32:32 <GK> GK: how do assertions and derivations get captured in RDF?  I don't see it.
16:33:07 <Luc> q?
16:33:19 <GK> Yolanda: need to explain what is meant by these terms on documents.
16:33:21 <satya> @Simon, prov-o describes what prov-dm means ontologically - did you mean something in addition to prov-o?
16:33:51 <GK> Luc: 6 months is a long time to next release.
16:34:20 <GK> ... also W3C has "3 month rule" for updates to active documents.
16:34:52 <GK> SimonM: our long term aims were on a 6 month period, but we can make interime releases.
16:35:18 <sandro> three month rule, fyi:
16:35:26 <GK> Luc: could you please identify (offline) date for next working draft?
16:35:27 <Zakim> - +1.760.705.aaff
16:35:39 <GK> SimonM: OK.  Maybe March/April?
16:35:57 <Luc> q?
16:36:12 <GK> Luc: Prov-O - what are your plans?
16:36:20 <Zakim> + +1.760.705.aagg
16:36:46 <GK> Khalid: need to align prov-o with current prov-dm, other topics not yet considered...
16:37:02 <GK> ... also have not determined next release date
16:37:33 <GK> ... Stephan will try to identify potential users from those identified by connections TF
16:37:53 <GK> Luc: can you please come back with a planned release date.
16:37:56 <Luc> q?
16:37:59 <dgarijo> we finished half of the list, so hopefully in a couple of telecons we're done with the alignement.
16:38:09 <Zakim> -Yolanda
16:38:23 <tlebo> satya
16:38:24 <pgroth> can't hear you satya
16:38:26 <dgarijo> @GK Satya
16:38:47 <pgroth> now
16:38:51 <khalidbelhajjame> we can hear you now
16:39:01 <Luc> the three month rule: a new draft of each active technical report at least once every three months
16:39:03 <Paolo> @GK satya
16:39:28 <satya> We plan to release next pwd by Feb - given the three month rule
16:40:07 <satya> and a major update before 2nd F2F
16:40:27 <GK> Luc: apart from 3 month rule, would be nice to have stable document by F2F meeting.
16:40:40 <GK> ... doesn't need to be formally released.
16:40:57 <Luc> q?
16:40:58 <GK> Khalid: should be fairly closely aligned by F2F meeting
16:41:08 <satya> we can discuss this during our call also next Monday
16:41:13 <GK> Topic: prov-dm
16:41:17 <satya> sure, I was planning to initiate release process by end of Jan/first week of Feb
16:41:20 <Zakim> - +1.760.705.aagg
16:41:39 <Luc> @satya, it looks good
<luc>Summary: Paolo has been working on specializationOf/alternateOf and collections, and feels that there is a good convergence of opinions on these topics.  When  the sections are ready, the WG will be invited to review and raise issues in the usual way. The aim is to have a document ready for internal review on Jan 19th, with a view to vote for release the following week. The editors have identified issues that they wish to close. Issues authors please review proposals, close issues and/or continue discussions by email.
16:41:39 <GK> Paolo: "complementOf" issue is reaching convergence.
16:41:47 <Paolo>
16:41:58 <GK> New next is (at link above)
16:42:29 <GK> q+ to say I still need to review the actual text, but agree with the direction of discussions
16:43:07 <Zakim> + +1.760.705.aahh
16:43:08 <GK> Paolo: the term "compelentOf" is still used, we need to formally agree new terms
16:43:34 <Paolo>
16:43:45 <GK> paolo: collections, has been substantially simplified
16:44:13 <GK> ... have long response from Stian to work though, but we do seem to be converging
16:44:27 <GK> ... hope to finish this successfully (in next week?)
16:44:49 <tlebo> +q to ask about global versus local naming in "complementOf" section and rest of document.
16:45:03 <GK> ... issue about whether collections actually belong - discussion on list, along with discussion of what is domain specific.
16:45:48 <tlebo> +1 to how the new specializationOf section looks

16:46:08 <Zakim> GK, you wanted to say I still need to review the actual text, but agree with the direction of discussions

16:46:46 <GK> ... have problem with distinction between global and local naming
16:47:15 <GK> ... think this is "very dissonant" (something that needs to be discussed?)
16:47:33 <Zakim> + +1.760.705.aaii
16:47:45 <GK> Luc: there is a specific issue addressing this.
16:49:08 <tlebo> q-
16:49:45 <GK> Luc: about vote about new terminology; granularity is too coarse (?)
16:50:17 <Luc> q?
16:50:26 <GK> q+ to ask why can't vote on the text as-is, or alternatively vote on choice of terminology, or...
16:50:38 <pgroth>  q+
16:50:48 <satya> +1, I think we need to discuss over raised issue first

16:56:40 <GK> Topic: Prov-o/Prov-dm
<luc>Summary: During the week, Tim produced a proposal to express accounts in RDF, making use of RDF abstract graphs.  Please discuss the proposal by email during the week, we will come back to this topic next week.
16:56:51 <GK> Discussion of accounts
16:58:11 <Zakim> - +1.760.705.aajj
16:58:20 <GK> Tim: proposing that account assertions are "RDF abstract graph" - set of triples independent of location.  Tryimng to core construct of activity to associate asserter with account graph.  Then addressing association of abstract graph with where it rests.
16:59:24 <GK> ... triple store organization of named graphs is "chaotic" - can re-use service description vocabulary.
16:59:47 <GK> q+ 
16:59:56 <pgroth> q+
16:59:59 <Luc> ack GK
17:00:07 <dgarijo> q+
17:00:59 <Luc> ack pg
17:01:38 <GK> GK: my comments (on list) really reeferring to *assertion* of an account, rather than problem of account being an "abstract graph".
17:01:41 <pgroth> ack pgroth
17:02:08 <GK> PaulG: question about typing of graph (missed details of response) 
17:02:20 <tlebo> +1 to confusion over Activyt versus Entity - partiatlly b/c I'm not sure yet :-)
17:02:32 <GK> DanielG: account as activity or entity?  Gets confusing.
17:03:00 <GK> ... distinguishes between account as wrapper, and activity that creates that wrapper.
17:03:27 <Luc> q?
17:03:31 <Luc> ack dga
17:04:14 <GK> Tim: yes, there is some confusion, indecision yet.  Details still to be worked out (wasAtributedTo property mentioned?)
17:04:48 <GK> Tim: still want to quality association with some activity (e.g. similar to derivedfrom?)
17:04:57 <Luc> q?
17:05:48 <GK> Luc: have raised issue of mixing accounts and entities.
17:05:54 <dgarijo> @Tim: anyway, this is the kind of discussion we needed to make this work. Thanks!
