== Minutes ==

  * michaelp2: **Topic: Recap of DC Task Group session**
  * michaelp2: Kai: People were interested in task group.
  * michaelp2: ... Topic of metadata provenance was perceived as relevant
  * michaelp2: ... Workshop itself was split in two parts:(1) presentation of several aspects, (2) open discussion of use cases.
  * michaelp2: ACTION: Add workshop slides to wiki
  * michaelp2: Kai: One of the central question was on how to model metadata provenance information vs. modeling "provenance as process" paradigm
  * michaelp2: ... For the second part, Antoine Isaac did lightning presentation of provenance in Europeana project / EDM.
  * kai: Antoines presentation: http://version1.europeana.eu/c/document_library/get_file?uuid=9d11f379-5e7e-471f-9821-c6a7779b77ee&groupId=10605
  * kai: See Slide 12 for the Proxies
  * kai: Michael: Europeana reinvented the metadata record by means of ORE procies
  * DGarijo> kai pls mute yourself
  * kai: ... Concerns about such complicated, non-standard models, that hide the information from the user by not making them explicit
  * michaelp2: ... No modeling of change information.
  * michaelp2: ... EDM "sort of" applies FRBR through the backdoor. That the "manifestation" is modeled as ore:proxy is problematic in my view.
  * michaelp2: Kai: I liked the approach. If you have this information in your domain model, model it as first-class data.
  * michaelp2: s/this information/this kind of information
  * michaelp2: ... OPM is very complicated, but if my metadata processes are that way, it might be a good fit.
  * michaelp2: ... Idea in the discussion: Is it possible to implement a subset of a rich data model like OPM or EDM in a simple model ar metametadata?
  * michaelp2: ... Can we do it in the spirit of Dublin Core, ie., extract the nuggets of core information and present it in a simple way?
  * michaelp2: Michael: We need a clear path back to OPM.
  * kai: Draft Charter Provenance WG: http://users.ecs.soton.ac.uk/lavm/draft-charter.html
  * michaelp2: Daniel: Luc's charter for Prov is in draft. It is not clear if OPM is going to be the main vocabulary.
  * michaelp2: ... There was a feeling the group the the OPM community has not made the effort to understand PML.
  * michaelp2: Michael: But people are very clear that they want to start with _a_ vocabulary.
  * michaelp2: Daniel: Question for Kai: How Do you mean to extract metadata from EDM to metadata prov metadata?
  * michaelp2: Kai: EDM needed to distinguish providers, so they extended the model.
  * michaelp2: ... I think an alternative would be to introduce a metalevel, to distinguish between data about resources and data about "triples" data.
  * michaelp2: ... This data can then be presented in a "Provenance Core".
  * michaelp2: Daniel: What if the original data already contained metalevel information?
  * michaelp2: Kai: We have to think about that. No clear answer at the moment.
  * michaelp2: ... What happens if metalevel information becomes part of the RDF standard and people start to use it for different things.
  * kai: Michael: Provenance Information has to be marked as such by classifying the graph as provenance graph (in case of named graphs)
  * michaelp2: ... Let's think about that in terms of a domain model over the next couple of weeks (with visualization!).
  * michaelp2: ... Provenance graph: Meant as attaching a provenance account resource to the standard named graph.
  * michaelp2: Kai: Can we start with translating the EDM use case?
  * michaelp2: Michael: I think we are close to a draft of a domain model.
  * michaelp2: ACTION: Work on first draft of domain model (low-key approach)
  * michaelp2: ACTION: Daniel to talk about some of his OPM use cases.
  * michaelp2: ACTION: Translation of Antoine's EDM ore:Proxy approach to metametadata
  * michaelp2: Daniel: We should highlight benefits of metamodel. Help seperating sources, how does this affect trust, etc.
  * michaelp2: Kai: Let's start working on Google Docs. Michael starts drawing with Inkscape.
  * michaelp2: ... Meeting adjourned.
