There is the executive summary, self-contained, short ... but would you like to publish an exhaustive document containing all use cases and requirements? 13:26:55 Paul: not really readable at this moment for people outside of the group ... so not really plan 13:27:53 Yolanda: there is a single document for all use cases: http://www.w3.org/2005/Incubator/prov/wiki/Requirements 13:28:02 ... no, http://www.w3.org/2005/Incubator/prov/wiki/Use_Case_Report 13:28:40 Andreas: it reads really well, now is the time to link to technical solutions, I guess would happen in next document 13:29:09 Yolanda: I'm interested in multumedia requirements and also digital signatures 13:29:28 Paul: I have talked to Dan Brickley from the SWXG about this 13:30:10 ChrisBizer has joined #prov-xg 13:30:12 aharth has joined #prov-xg 13:30:19 ... a lot of techies people, that might cover just an aspect of the provenance problem space and come up with their own solution 13:31:00 ... can be the liaison, but hard to get their attention 13:31:14 Chris: well, this is perhaps a indication for us to work more on the technical aspects too 13:31:21 ... to appear in their radat 13:31:26 s/radat/radar 13:32:26 Chris: state of the art document is good, but how to go forward now ? 13:32:36 ... feel there is consensus on the OPM model 13:33:08 ... but we could go forward 13:35:32 ssahoo2 has joined #prov-xg 13:38:07 Chris: I think there is some frustration from people who would like to test things now 13:41:48 Yolanda: having a document that explains the mappings between various models such as Provenance Vocabulary, OPM, etc. is actually our plan 13:41:57 ... we might not go further 13:47:52 Chris: we have technical people in the group, deployment people, and there is urgent pressure from the LOD community, what I suggest is to suggest technical solutions, simple vocabulary that we agreed on, or mappings between vocabularies 13:50:29 DeborahMcG has joined #prov-xg 13:50:51 ssahoo2 has joined #prov-xg 13:51:20 ssahoo2 has joined #prov-xg 13:57:47 Paul: we have now the requirements, but we haven't done yet the gap analysis, i.e. see which technology match which requirements 13:57:56 ... perhaps this could be our next step 13:59:32 Chris: I belive the soa document should contain some mappings between the various models 14:00:06 Yolanda: we have the user requirements report ... our timeline schedule a soa report (end of June) and a roadmap (end of September) 14:02:37 Paul: assuming OPM at the core, we have mappings between PML, Provenance Vocabulary, Provenir, PREMIS and OPM 14:05:09 Yolanda: perhaps we could start collecting in a single place these mappings, even if we do not cover all the list of related technologies, but we have a start 14:05:55 Yogesh: should we not first do the gap analysis, i.e. check which model fits which use cases before working on the mappings? 14:06:07 Yolanda: I think we should do both 14:08:11 aharth has joined #prov-xg 14:09:26 All, I am afraid that I need to leave now. Bye and thanks. 14:09:40 thanks kerry for joining 14:09:47 hope it was useful 14:09:47 -Kerry 14:14:43 Raphael: take inspiration of the mappings tables from the Media Ontology, http://www.w3.org/TR/mediaont-10/ 14:19:03 Raphael: another suggestion is to take a concrete example from the use case document and try to represent the provenance information with each models and ontologies 14:19:16 ... in order to compare the resulting representations or rdf graphs 14:19:43 Jun: yes, we intend to do that, and give feedback to authors of models of which use cases are realizable or not 14:19:54 Chris: should not be a task for the Provenance challenge? 14:20:01 I have made the request to generate http://www.w3.org/2010/04/25-prov-xg-minutes.html raphael 14:28:21 ChrisBizer has joined #prov-xg 14:28:32 ChrisBizer has left #prov-xg 14:33:17 raphael has joined #prov-xg 14:33:18 jun has joined #prov-xg 14:33:31 scribenick jun 14:33:39 scribenick: jun 14:33:42 ChrisBizer has joined #prov-xg 14:33:42 Yolanda: update on the discussion of the state of art document 14:33:59 Yoland: Luc proposed to use a matrix to do a technology gap analysis 14:34:25 Yolanda:not only the gap but also the strength and weakness of these technologies 14:35:02 Yolanda: a matrix is a systematic way to organize things 14:36:21 Yolanda: Luc also suggested that we should have some sense of goals/scope to anchor, e.g., what my needs are 14:36:49 Yolanda:Paolo suggested to use the RDF next step paper as a starting example for the exercise 14:37:46 Yolanda: we will use the three use case scenarios to see how they cover your goals 14:38:45 Yolanda: Luc suggested a block diagram for each use case, an architecture picture, of how provenance pieces could fit together for a use case 14:39:46 Yolanda: maybe there could some themes in the use case scenario, to reflect the goals, to help us to have a better idea about "goals" 14:40:09 Yolanda: we talked more about how the matrix could look like 14:40:49 Yolanda: maybe we can look at one particular scenario, to go through the exercise 14:41:38 Yolanda: take one scenario, articulate tech. requirements, the goals; to draw some architecture, provenance solution for the scenario; and then look at relevant technologies and systems 14:42:39 Topic 2: Gap analysis study 14:43:10 Yolanda: James also suggested to keep the content in the matrix brief, and link to the "why"s 14:48:15 Chris: suggested to define the matrix for aligning vocabularies 14:52:30 Topic 3: definition of provenance 14:52:50 Yolanda: everybody puts their def. on the wiki page: what is provenance 14:53:11 Chris: maybe someone has done a survey of provenance definition? 14:53:31 Paul: Luc has a pretty good collection of the definition and will point to his chapter on the wiki 14:55:01 Topic 4: define the matrix for provenance vocabulary mapping 15:04:12 s/Topic 2:/Topic: 2 15:04:17 s/Topic 3:/Topic: 3 15:04:21 s/Topic 4:/Topic: 4 15:04:28 I have made the request to generate http://www.w3.org/2010/04/25-prov-xg-minutes.html raphael 15:06:16 s/scribenick jun/Topic: 2.
