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" .
