If David is coining his own ContextObjects, he could add his own Linked
Data rft_id in addition to or instead of the dx.doi.org URI. The rft_id
key is repeatable. If he does coins his own Linked Data URI, though, I
would recommend having his Linked Data URI assert owl:sameAs with the
dx.doi.org URI in the RDF.

OTOH, if he's merely consuming ContextObjects via his own OpenURL
Resolver and wants to deliver the content locally, he treat the
dx.doi.org URI as a mere identifier and direct the requester to the copy
he is hosting instead.
