At the risk of being pedantic :-)

This is referring to the oai-identifier scheme, rather than the more general
OAI identifier (unique within a repository and a URI).

"An item is conceptually a container that stores or dynamically generates
metadata about a single resource in multiple formats", so it follows that
the identifier for the OAI item uniquely identifies the resource, which
fulfills the DC definition:
"An unambiguous reference to the resource within a given [OAI] context."

What is not defined is how to resolve an oai-identifier to the resource, but
DC doesn't require that.

All the best,
