[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

[16:16] <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
