The group approved the integration of this proposal into the upcoming release of the documents. 15:38:39 <Curt> pgroth: some discussion around invalidation/destruction, would be nice to have for symmetry 15:38:42 <Luc> http://dvcs.w3.org/hg/prov/raw-file/default/model/working-copy/wd5-prov-invalidation.html 15:38:50 <Curt> ... not too much disagreement around it 15:39:08 <Curt> pgroth: incorporate into DM? 15:39:40 <Curt> luc: we took into account the feedback from macted, graham, and other discussion, folded into the document^^ 15:39:49 <Curt> ... a few people commented they like it 15:39:52 <pgroth> q? 15:40:04 <pgroth> Proposal 7: Incorporate the invalidation/destruction in prov-dm for immediate release 15:40:11 <smiles> +1 15:40:12 <Curt> +1 15:40:13 <khalidbelhajjame> +1 15:40:13 <tlebo> +1 15:40:14 <TomDN> +1 15:40:15 <MacTed> +1 15:40:17 <dgarijo> +1 15:40:18 <SamCoppens> +1 15:40:20 <jcheney> +1 15:40:22 <stephenc> +1 15:40:22 <sandro> +1 15:40:28 <satya> +1 15:40:29 <Paolo> +1 15:40:29 <zednik> +1 15:40:42 <pgroth> accepted: Incorporate the invalidation/destruction in prov-dm for immediate release 15:41:09 <smiles> q+ 15:41:12 <Curt> pgroth: that covers this synchronous release. any other issues about that release? 15:41:19 <pgroth> ack smiles 15:41:29 <Curt> smiles: the documents refer to each other with correct references? 15:41:53 <Luc> yes, it's part of the release process 15:41:55 <tlebo> prov-o's references need to be updated too. That's just part of publication, right? 15:41:59 <Curt> pgroth: luc to coordinate release, can you check that? 15:42:02 <Curt> luc: yes 15:42:13 <Luc> q+ 15:42:13 <pgroth> q? 15:42:22 <pgroth> ack Luc 15:42:33 <Curt> luc: we need to agree on the actual release date. 15:42:55 <Curt> ... two approvals to pass, get short names for new documents, then publication requests for all new documents 15:43:08 <Curt> ... need 4 working days of notice, what is a reasonable date? 15:43:29 <Curt> ... can only publish on tuesday or thursday 15:43:36 <Curt> ... perhaps tuesday May 1? 15:43:52 <pgroth> is that a holiday sandro? 15:43:57 <smiles> yes, possible, I think 15:43:57 <Curt> luc: all editors would need to be ready by next Tuesday or Wednesday 15:43:58 <tlebo> That is very tight for me. 15:44:27 <jcheney> q+ 15:44:39 <pgroth> ack jcheney 15:44:52 <Curt> jcheney: how much work to get from where we are with constraints to fit required style? 15:45:12 <Curt> luc: the version was html 5 compliant mostly, not sure if you have preserved that 15:45:30 <Curt> luc: most things get taken care of to create the compliant files 15:45:52 <Curt> ... look at models subdir in mercurial to see it 15:45:58 <pgroth> q? 15:46:15 <Curt> jcheney: will luc/paolo do that publication work or james? 15:46:30 <Paolo> I can help but I have not done it before 15:46:36 <Curt> luc: if there aren't many HTML problems, luc could do it in a couple hours, would be nice to get some help with that 15:46:50 <Curt> sandro: all editors should try to make compliant html and check links 15:47:28 <Curt> pgroth: try end of next week, then go for May 3? 15:47:57 <Curt> pgroth: would make the request for the names 15:48:08 <Curt> luc: yes, transition request today, will copy all editors 15:48:34 <Curt> luc: time to make the document compliant with rules after making publication request 15:48:42 <smiles> yes 15:48:45 <Luc> +1 15:48:49 <Paolo> ok 15:48:53 <tlebo> q+ 15:48:55 <Curt> pgroth: Editors -- May 3 release ok? 15:49:08 <Curt> tlebo: what needs to be done by May 3 15:49:26 <Curt> pgroth: make the compliant document available 15:49:31 <pgroth> ack tlebo 15:49:44 <Curt> luc: that should be done by April 30 to start process and checks 15:50:00 <Curt> tlebo: 4/30 sounds reasonable 15:50:01 <tlebo> q- 15:50:19 <pgroth> q? 15:50:32 <tlebo> and the WG! :D 15:50:34 <Curt> pgroth: 4/30 for editors to be ready, 5/3 for actual release 15:50:38 <pgroth> Topic: Discussion on OWL RL <pgroth> Summary: There is a requirement that the ontology be "lightweight". This has been operationalized by ensuring that the ontology is compatible with OWL-RL. However, this was causing difficulty in appropriately mapping to the DM. Through discussion on the mailing list, a new approach was suggested where OWL-RL was treated as a baseline but certain deviations were allowed but needed to be documented. The group agreed that this was guidance the editors of prov-o should follow. 15:51:12 <Curt> pgroth: current ontology compliant with RL, but has difficulties modeling all constructs of the DM 15:51:32 <Curt> ... RL is operationalize 'lightweight ontology' requirement 15:51:53 <Curt> ... editors and PROV-O people have a hard time with the RL constraint 15:52:08 <Curt> ... would be nice to relax that requirement and allow certain other non-RL constructs to be used 15:52:29 <Curt> ... Is that ok? How do we make sure we remain 'lightweight'? 15:52:59 <Curt> <silence> 15:53:00 <pgroth> q? 15:53:01 <tlebo> q+ 15:53:10 <dgarijo> I think that the RL++ proposed by Tim made sense. 15:53:14 <pgroth> ack tlebo 15:53:29 <Curt> tlebo: we generally agreed to relax RL slightly, and enumerate the violations 15:53:44 <Curt> ... clearly point out the constructs that aren't recognized by RL 15:53:58 <Curt> ... RL reasoners can still omit those constructs 15:54:12 <Curt> ... RL is the baseline for lightweight characteristics, but allow a few violations 15:54:34 <Curt> pgroth: which constructs will you need? unions on domain/range? 15:55:03 <Curt> tlebo: yes, there are now two unions on domain/range, and that addresses design issues, a nice option to include those 15:55:25 <Curt> ... if there are other things we want to use, each kind of construct will be considered individually 15:55:36 <pgroth> q? 15:55:40 <Curt> ... unions alone are helpful 15:55:49 <dgarijo> hadRole and hadActivity are the ones with unions 15:55:59 <Curt> pgroth: not very controversial. 15:56:24 <Curt> luc; isn't this already in the release we've approved? 15:56:44 <Curt> pgroth: yes, but this is a real change in the direction of PROV-O. Want support from the group on that. 15:57:33 <pgroth> proposal: the ontology will be based on OWL-RL and any deviations from that profile will be documented in the ontology documentation 15:57:45 <tlebo> +1 15:57:49 <dgarijo> +1 15:57:49 <satya> +1 15:57:49 <jcheney> +1 15:57:49 <Curt> +1 15:57:51 <Paolo> +1 15:57:51 <khalidbelhajjame> +1 15:57:52 <TomDN> +1 15:57:53 <smiles> +1 (to the limited extent of my knowledge) 15:57:54 <stephenc> +1 15:57:56 <sandro> +1 15:57:56 <SamCoppens> +1 15:57:59 <zednik> q+ 15:58:17 <tlebo> q+ 15:58:17 <Curt> zednik: do we have guidelines on which deviations will be permitted? 15:58:23 <pgroth> ack zednik 15:58:36 <Luc> q+ 15:58:38 <Curt> tlebo: unions in domains/ranges ok for now, other changes need to be considered 15:58:52 <pgroth> ack tlebo 15:59:00 <tlebo> q- 15:59:03 <pgroth> ack Luc 15:59:03 <zednik> q- 15:59:06 <Curt> zednik: what about existential dependents (?)? 15:59:28 <Curt> luc: RL will work ok even with non-RL compliant constructs 15:59:34 <Curt> tlebo: yes, it will skip over them 15:59:56 <tlebo> the simplicity of RL is that it's based on a set of rules application. 16:00:03 <Curt> pgroth: try to stick with RL as a baseline 16:00:35 <tlebo> @zednik, go a head and raise the ISSUE so we can consider it. 16:00:41 <Curt> pgroth: make an argument for each other non-RL thing to use 16:00:55 <pgroth> q? 16:01:05 <pgroth> accepted: the ontology will be based on OWL-RL and any deviations from that profile will be documented in the ontology documentation 16:01:11 <Zakim> -Satya_Sahoo 16:01:11 <TomDN> Zakim, unmute me 16:01:12 <Zakim> TomDN should no longer be muted 16:01:12 <Zakim> -??P12 16:01:13 <Zakim> -tlebo 16:01:13 <Zakim> -??P6 16:01:14 <SamCoppens> Thanks, Bye 16:01:14 <zednik> @tlebo, raise the issue on guidelines or on existential dependence? 16:01:15 <Zakim> -Luc 16:01:17 <Zakim> -dgarijo 16:01:19 <Zakim> -khalidbelhajjame 16:01:22 <Zakim> -Sandro 16:01:23 <Zakim> -jcheney 16:01:25 <SamCoppens> SamCoppens has left #prov 16:01:29 <Zakim> -TomDN 16:01:31 <Zakim> -MacTed 16:01:35 <pgroth> rrsagent, set logs public 16:01:39 <Zakim> -Curt_Tilmes 16:01:40 <pgroth> rrsagent, draft minutes 16:01:40 <RRSAgent> I have made the request to generate http://www.w3.org/2012/04/19-prov-minutes.html pgroth 16:01:45 <pgroth> trackbot, end telcon 16:01:45 <trackbot> Zakim, list attendees 16:01:47 <Zakim> -??P14 16:01:53 <Zakim> As of this point the attendees have been Curt_Tilmes, Sandro, MacTed, +1.315.723.aaaa, tlebo, Satya_Sahoo, [ISI], khalidbelhajjame, Luc, TomDN, jcheney, dgarijo, SamCoppens 16:01:53 <trackbot> RRSAgent, please draft minutes 16:01:53 <RRSAgent> I have made the request to generate http://www.w3.org/2012/04/19-prov-minutes.html trackbot 16:01:54 <trackbot> RRSAgent, bye 16:01:54 <RRSAgent> I see no action items 16:01:56 <Zakim> -??P1 # SPECIAL MARKER FOR CHATSYNC.
