I don't know. Time is instantaneous, so you couldn't specify it as a generation time, but could you just define a domain specific attribute for the generation? wasGeneratedBy(ex:MonaLisa, [ex:creationEstimate="1503-1519"]); Is it ok to leave out both activity and time in order to specify generation attributes? DM would seem to allow it since everything but entity is optional. How would such a thing get mapped to RDF? ex:MonaLisa a prov:Entity . _:a a prov:Activity . _:g a prov:Generation . ex:MonaLisa prov:wasGeneratedBy _:a . _:a prov:hadQualifiedGeneration _:g . _:g a prov:QualifiedInvolvement . _:g prov:hadQualifiedEntity ex:MonaLisa . _:g ex:creationEstimate "1503-1519" . Probably easier to just express this outside PROV: ex:MonaLisa ex:creationEstimate "1503-1519" . Curt
