Hi Jim, It is intentionally that we use typed literals here, and not identifiers. If we allow identifiers, then in effect we would have introduced a new relation; it would be better defined as prov-dm relation, rather than hidden in a qualifier. What's wrong with "the role of president" here? Luc On 06/11/11 15:19, Jim McCusker wrote: > Make Roles resources like Entities.
