PROV-ISSUE-402 (Feedback_SM): Feedback on the feedback from Simon Miles [Mapping PROV-O to Dublin Core]

Hello Daniel, Kai, Michael,
 
I've read through the DC-PROV mapping documents, and have a few comments (mostly regarding the primer, as this is the substantial document so far). At this stage, my feedback is just comment without much constructive on how to address those comments, but I am happy to help do so.
 
The primer is very good, and the first few sections in particular sets out the issues clearly and helpfully.

 

I found that the sections from "What is ex:doc1" onwards referred a bit too much to the technical details of the mapping. I think we could introduce the key issues at a higher level first.

 

The documents seem to assume that we are mapping DC RDF to PROV-O (rather than DC to PROV more generally), but I didn't see this explained anywhere.

 

Many points (such as the questions at the end of "What is ex:doc1") would benefit from a running example to make the ideas concrete.

 

I think it would help clarity to come up with more descriptive names than "Stage 1" and "Stage 2".

 

As it's a draft, there are clearly some explanations missing, and so I note some points that need to be clarified:

 - In "What is ex:doc1", option 1: why are the mappings potentially bloated? Needs higher level explanation.

 - In option 2, why are the PROV semantics unclear? I wasn't clear what you were trying to say.

 - What is the connection of the dc:publisher figure (which needs explanation itself) to the text?
 - Are "PROV Specializations" the same as "specializationOf" in PROV? I didn't see the connection, and if there is no connection we should not use the term.
 

I have to think through all the proposed mappings. Some direct mappings seem maybe not intuitive. I believe that PROV aims to cover a smaller area than DC (i.e. only provenance) but more generally (i.e. any kind of past occurrence). Therefore, I would not expect PROV terms to usually be subclasses of DC terms.

 

For example, I don't think wasRevisionOf is intended to be more specific than isVersionOf, even if under certain readings of the words "revision" and "version" this might be intuitive (also, I remember debating whether isVersionOf actually links different versions of a resource, or links a version of a resource to the general document).
