The counter argument is that the dcterms:hasVersion/isVersionOf solution
isn't documented anywhere and other solutions are plausible. Without a
systematic connection, SPARQL connections between Work and Manifestation
become a guessing game.

The question is, how much grief will the RDF designer get for wanting to
coin a new 303 URI? If the framework is flexible, then go ahead and have
them coin a 303 URI for Expression:

http://example.org/expression/45678 a frbr:Expression .

My suggestion of using a hash assumes that Expression will always be a
twin to Work and is easily piggybacked on it without fighting for
infrastructure support. If and when Expressions deserve 303 URIs, the
old hash URIs can migrate to the 303 URI using owl:sameAs.
