PROV-ISSUE-454 (key across relations/objectss): can the same identifier be used for different relations objects [prov-dm-constraints] http://www.w3.org/2011/prov/track/issues/454 Raised by: Luc Moreau On product: prov-dm-constraints We have the following two uniqueness constraints. http://dvcs.w3.org/hg/prov/raw-file/default/model/prov-constraints.html#key-object http://dvcs.w3.org/hg/prov/raw-file/default/model/prov-constraints.html#key-relation It is not clear to me if entity(e123) agent(e123) are acceptable. (To me, they should be, since we don't state the set of agents to be disjoint from any other set) Likewise, can we write used(event1234,a1,e1,attrs1) and wasGeneratedBy(event1234,e2,a2,attrs2) Probably not. Note: if we allow the two above, then I am not sure that strict ordering is wise in ordering constraints.
