GenericCollection has files() interface

[azaroth42]

Issue: generic_collection lacks files() interface but a collection can have associated files.

@azaroth42 I was building from the Application Profile text description.

If I'm reading the doc correctly, then

<hasFile> rdfs:subClassOf <contains> .
<contains> rdfs:subClassOf <hasMember> .
<hasMember> rdfs:subClassOf ore:aggregates .
ore:aggregates a rdf:property .

In Ruby(ish):

hydra:hasFile < hydra:contains < hydra:hasMember < ore:aggregates

Am I correct? If so, then a GenericCollection hasFile because it can aggregate anything.

But properties in code don't inherit as nicely as they do in RDF, so I think a GenericCollection implementation is going to need each of the sub, sub-sub, and sub-sub-sub-properties that are defined in the application profile.

Added hasFile explicitly in the AP doc. Note that it is in the diagram, we
just missed it in the listing. Thanks!

Does this impact samvera/hydra-pcdm#20?

[azaroth42]

Not sure what the issue is particularly, but pcdm:Collection only has
related objects, not files directly. So in PCDM, a collection should
lack a files() interface.

Based on @azaroth42's comment this is either resolved or irrelevant. Closing it.
