[16:00] == kai [869b3c65@gateway/web/freenode/ip.134.155.60.101] has joined #dcprov [16:00] <kai> Hi together [16:00] <oemer> Hi [16:01] <@DGarijo> Hi [16:01] == michaelp2 [~panzerm@132-174-21-208.ip.oclc.org] has joined #dcprov [16:03] <kai> Agenda: http://wiki.bib.uni-mannheim.de/dc-provenance/doku.php?id=agenda [16:03] <oemer> Topic: Housekeeping [16:08] <kai> Result 1: Ömer is scribe per default. [16:09] <oemer> michaelp: suggestion for new intervall for telecons (every 2 weeks) [16:09] <kai> Result 2: Kai will keep track of sending agendas and announcing new meetings [16:10] <kai> Result 3: Telcos are not necessarily every week, will be decided at end of ech telco [16:10] <michaelp2> s/Result/Resolution [16:11] <kai> Topic: Summary of the group work so far [16:11] <kai> Link: http://wiki.bib.uni-mannheim.de/dc-provenance/doku.php?id=agenda [16:11] <kai> Link: https://docs.google.com/document/edit?id=1xEdXn95l6TFINtaEmJj45YzzRuqPMqeSit6_MUzHdm0&hl=en&authkey=COSCnIAO&pli=1# [16:16] <oemer> Extending and correcting the summary [16:17] <oemer> ACTION: Create Starting Point for Extration (Ömer) [16:17] <kai> ACTION: Extending and correcting the summary [16:18] <kai> Topic: Europeana Example [16:18] <kai> Link: http://wiki.bib.uni-mannheim.de/dc-provenance/doku.php?id=europeana_example [16:20] <oemer> Kai: Main resource in the center, describing resources around; 2 proxies (above and below the center): 2 aggregations [16:21] <oemer> … Question to Antoine: Why is the view in the center? [16:22] <oemer> michaelp: aggregation is what they would recieve as a data packet (what EDM expects) [16:24] <oemer> … I think the aggregation shold be part of it [16:25] <oemer> Kai: Proxy as a placeholder for resource of Mona Lisa painting; Aggregation as a placeholder for record of the painting [16:26] <oemer> michaelp: The painting has this URI; the aggregation can contain more [16:29] <oemer> Kai: Question is: What would be appropiate to represent same data wic is intuitive [16:30] <oemer> … Could this data be generated directly out of the model whith rules we merge out of the resource [16:32] <oemer> michaelp: Proxy here has the utility of enabling talking about the aggregate resource. Cutting proxy out is good a idea [16:35] <oemer> Kai: It's like always in DC, we lose Information. Idea: Whatever it is actually done, we want to know evertyhing possible to know, to distinguish between sources [16:36] <oemer> … should be possible to provide a simple approach like the DC. [16:38] <oemer> michaelp: They would have anything except the proxy anyway. Would have the aggregated resources. If only created for prov we could cut it out. [16:39] <oemer> Kai: I will find out what the Idea of aggregation is [16:40] <oemer> ACTION: Asking Antoine (Kai) [16:40] <oemer> Kai: Finding out role between proxy and aggregation [16:45] <oemer> michaelp: Dashbox: We have to make an assumption between the box and the content of the box [16:46] <oemer> Kai: It is just a graph, named somehow. Like prov information, We can know sth, about who cretaed information. Like resource. [16:48] <oemer> ACTION: Provide new examples (Kai= [16:49] <oemer> Kai: Idea is to give very simple rules. Tell people why to do that this way. [16:52] <oemer> michaelp: Relation betwenn ORI web resource and painting [16:52] <oemer> Kai: Maybe we need some vocab to express, and how it can be done in a simple way [16:55] <kai> Topic: Introduction to OPM (Daniel) [16:55] <@DGarijo> http://www.slideshare.net/dgarijo/opm-overview [16:57] <oemer> Daniel: No use of ontology cover source → they nevertheless did it [16:58] <oemer> … artifatcs like snapshots of processes [17:12] <oemer> michaelp: What is OPM lacking [17:13] <oemer> Daniel: The notion of account is abstract. COuld be a part of the graph, but it may have more than one graph. eg If you are an agent and are participating in more than one OPM graph [17:14] <oemer> … Would be better to extent the notion of annotation. eg sth. to disacount / filter prov by source [17:15] <oemer> Kai: What do we want to accomplish. In whic apps could OPM be used. e.g. could Europeane use OPM, [17:17] <oemer> … OPM is somewhat incomplete. [17:20] <oemer> ACTION: Try to find real-world models of OPM (Daniel) [17:28] <oemer> Kai: Try to find a model which is simple enough; just for outside users. [17:29] <kai> Topic: Domain Model [17:29] <@DGarijo> Just one thing: artifacts can be snapshots of dynamic objects, n ot processes ;) [17:30] <oemer> ok, sorry :) [17:31] <@DGarijo> np, i spoke too fast :( [17:32] <oemer> no, it's just hard for me to keep track, i could understand you very well [17:33] <@DGarijo> ok! [17:36] <oemer> Kai: Do we need the metadate annotation set? [17:38] <oemer> michaelp: The description set would be sth. like a named graph. You would have an URI for the annotations set. [17:39] <oemer> … You would have a way of gouping them together which makes sense [17:39] <oemer> Kai: Possibility to describe a description set in RDF [17:40] <oemer> michaelp: Depends on how to model you desc. set [17:44] <oemer> Kai: Focusing on examples
