if the URIs denote individual, use owl:sameAs
if the URIs denote classes, use owl:equivalentClass
if the URIs denote properties, use owl:equivalentProperty

if you are not sure about what they denote (either because one of them
denotes sometimes an individual and sometimes a class, or because both
do not denote the same kind of thing), then you are *already* in OWL-Full...

In OWL-DL (and Lite), the sets of classes, individuals and properties
are disjoint, so there should be no ambiguity.
