Compatibility with common patterns for linking assets to policies · Issue #184 · w3c/poe · GitHub

Split from #158 , in the context of https://lists.w3.org/Archives/Public/public-poe-comments/2017Apr/0005.html :

The POE pattern is centered on rights statements (which for us correspond to the POE "policy" notion). And the property that indicates the policy that applies to an asset (odrl:target) goes from the policy to the asset.
The most common pattern, and we believe the one that fits most application scenarios, is the one where links in the other direction and use properties that are usually used for representing metadata on assets, like “simple” (DC) properties. Our (rightsstatements.org) specific approach to this can be seen in the "Class for Rights Statements" and "Object Metadata Examples" at http://rightsstatements.org/files/170106requirements_for_the_technical_infrastructure_for_standardized_international_rights_statements_v1.2.pdf
It's also in the ccRel W3C submission: https://www.w3.org/Submission/ccREL/ and https://creativecommons.org/ns (using cc:license/xhtml:license)
But I guess you're already quite familiar with the pattern anyway…
Of course I’m not saying that the ODRL pattern is bad. It is fully legit, imho. But considering existing practices, I think the matter of the equivalence between patterns should be given a much more prominent place, and be ironed out to remove any doubts one could have.

As a matter of fact it seems you are aware of the problem: the RDF/OWL document refers to a correspondence between expressing rights statements with dct:license and the “official” pattern (section 5.1.1, https://www.w3.org/TR/2017/WD-odrl-vocab-20170223/#rdfowl )
This goes in the right direction, but:

• in fact the axiom is not presented very explicitly: it is refered to as ‘this axiom’ but not spelled out
• we are not sure that dct:license is the right property (level) for such axiom. We consider dct:rights (a super-property of dct:license) to be a more appropriate level for such linking, as some policies (rights statements) are not necessarily licenses.
• I really don’t see why this is in a section introducing an ‘RDF/OWL encoding’. It is not a matter that seems specific to an OWL ontology. And in fact it doesn't seem to appear in the RDF/Turtle serialization of the ontology: http://w3c.github.io/poe/vocab/ODRL22.ttl . It may be better to devote a specific section of another document, or even a document of its own (maybe one that would tackling the following issue at the same time?)
