- michaelp2: ACTION: Put agenda an Wiki
- michaelp2: ACTION: Three slides with voiceover for workshop presentation
- michaelp2: (Michael)
- michaelp2: Kai: Phone call with Alex Haffner; he has good UC
- michaelp2: http://www.w3.org/2009/12/rdf-ws/
- michaelp2: RDF Next steps
- michaelp2: Main finding of workshop: http://www.w3.org/2001/sw/wiki/index.php?title=RDF_Core_Work_Items&oldid=1980
- michaelp2: Kai: Make contact to RDF community
- michaelp2: … Ivan Herrman, Chris Bizer, etc.
- michaelp2: ACTION: Write email to Chris Bizer (Kai)
- michaelp2: Topic: Alex Haffner's UC case
- michaelp2: … where metadata provenance is needed for linked data application of RDA
- michaelp2: Slide 35-37
- michaelp2: Kai: Introduction of a “Relator” entity into a S P O triple to hang assertions about the triple off of.
- michaelp2: … This is a challenge to interoperability, because it introduces something that is foreign to the ontology (here: RDA)
- michaelp2: Daniel: There exists a transformation of Dublin Core relations into OPM
- DGarijo: the slides I was talking about (From slide 29): http://openprovenance.org/tutorial/slides/5-opm-profiles.pptx
- michaelp2: Michael: I think what Alexander talks about is out of scope for us. What he is trying to represent is still information inside the domain model. It's not about the data. It's about provenance in general.
- michaelp2: … It's a boxing issue.
- michaelp2: Michael: We don't want to find a general solution how to break the design limitation of RDF to make statements that are more than Subject/Predicate/Object (or how to express metastatements in general in RDF.)
- michaelp2: Kai: Can we flag a property like dc:subject to indicate that there is additional provenance information associated with it?
- michaelp2: Michael: Let's try to deal with this together with the next topic:
- michaelp2: Topic: Working def. for metadata prov
- michaelp2: Michael: My take: Metadata provenance is information about the data aspect of a piece of metadata that is independent of the domain model of the resources described by the original piece of metadata.
- michaelp2: Daniel: Def. sounds good, but needs examples for what is metametadata and what is not.
- michaelp2: Kai: Are there really independent things?
- michaelp2: … or are there things that are relevant to many domains, which is something different.
- michaelp2: ACTION: Add examples to definition
- michaelp2: (Michael)
- michaelp2: Kai: Overlap with Web of Trust. So Quality measure has to be part of metadata provenance.
- michaelp2: … Might not be intuitive
- michaelp2: … This challenges the notion of independence of domain. Does a quality measure cross the lines of domain vs. out-of-domain?
- michaelp2: … Is something like “quality” in general about the data or the described resources?
- michaelp2: ACTION: Capture discussion as Google Docs and on mailing list. (Kai)
