Looking at my previous answer again I think I should take another run at
this  :-)

One way of thinking about equivalence is in terms of substitution: if :x
:equiv :y when is it safe to substitute :x with :y?

The default is: it's not safe (obviously).

:x equivalentClass :y -> safe when used as a class (e.g. rdf:type :x)
:x sameAs :y -> always safe (watch out!)
:x sameConceptAs :y -> safe in subject positions
:x sameWorkAs :y -> safe for author, creation date
:x sameManifestationAs :y -> safe for the the above, and length (?)

Does that help?
