rationale: The current thinking is to associate one or more files containing metadata with the binary files they describe using iana:describes predicates between PCDM:File objects.
But there is still some unknowns (for me at least) as to what that looks like in Ruby, Fedora, and Solr.
Done when: we can demonstrate one or more approaches on how to associate a metadata file with the file it describes using iana:describes predicate.
