Use a property bridge that creates rdf:type statements. Assigning an instance X to a class C in RDF is nothing more than creating a statement "X rdf:type C"!
So: Make a class map for the role table. It should have a uriPattern "http://xyz.com/role_@@ROLE.PERSON_ID@@ ". It should have a property bridge which has d2rq:property rdf:type, and a uriPattern "http://xyz.com/@@LOOKUP.ROLE_NAME";. This property bridge also needs a d2rq:join "ROLE.ROLE_ID=LOOKUP.ROLE_ID" (or whatever the ID column is called in the LOOKUP table).
