Re: Using prov:hadRole with prov:Attribution

Thanks a lot, Luc.

The context of my question concerns work on DCAT-AP [1] and GeoDCAT-AP
[2], two DCAT-based metadata profiles, which are meant to be used as
metadata interchange format across European data portals.

One of the issues we are trying to address is about how to model roles
of an agent wrt a catalogue or dataset, not supported in DCAT, Dublin
Core, etc., but used in other metadata standards, as ISO 19115 and
SDMX.

One of the options under consideration is to use PROV-O, but, if
possible, by using simpler a pattern wrt the one illustrated in
PROV-DC for dct:creator, dct:contributor, etc. [3].

The current proposal in GeoDCAT-AP [4] is to use a qualified
attribution, + dct:type to specify the role:

[] a dcat:Dataset;
  prov:qualifiedAttribution [ a prov:Attribution ;
    dct:type a:role ;
    prov:agent a:Agent ] .

The choice of dct:type was due to the fact that (a) prov:hadRole is
not used for prov:Attribution in the PROV specs, and (b) rdf:type
might be too "strong", since roles may not be modelled as RDFS/OWL
classes/properties, but only as skos:Concept's.

Can this be acceptable and compliant with the PROV model? If not,
could you suggest an alternative solution?

Any feedback would be very much appreciated.

Thanks!

Andrea
