How about wikipedia articles / dbpedia articles? they have uris which 
redirect to a preferred canonical one quite often - likewise rel 
canonical as used throughout the web for "documents" ?

agree, seems to be the same functionality as described by rel=canonical 
which is in general use too.

Unsure if I agree with this one.. I can't see what it brings to the 
table above multiple values for owl:sameAs, or in the other use case 
over multiple values for rdfs:label ?
