If I have two datasets in RDF with some common entries, how can I
generate owl:sameAs links? Is there a way to do this within Virtuoso,
or do I have to make a separate program? I would guess in either case
it would be done by selecting all entries from one of the datasets,
and then for each entry do a sparql query to select one or more
candidates for linking and then apply some rules to determine whether
or not to make a link?

SPARQL is a formidable rules language.
Make a SPARQL CONSTRUCT from the two RDF datasets (which would have
their own Graph IRIs if hosted in Virtuoso).
Basically use SPARUL.
