The protégé owl DC document [1] defines DC URIs as OWL Annotation Properties. Since annotation properties have no semantics, one won't be able to apply restrictions or reason about them. Redefining the DC terms as datatypes will lead to OWL Full upon integration of two different documents, which may not be handled by DL reasoners. Ideally, we would have an OWL ontology that defines the various terms (i.e. the class of Author), and makes object properties out of DC terms. However, this redefinition exemplifies the need for another URI. A challenge is which URIs to mint for such a document, and moreover, what URIs shall we use for the various authors. Unlike PubMed articles, I am not aware of a system to generate consistent and unique URIs for authors.
