You are right, I think this was caused by a copy-and-paste error in ProvRDF.

I've fixed this in
http://www.w3.org/2011/prov/wiki/ProvRDF#Started_by_activity

by introducing prov:wasStartedByActivity with range Activity.

We could have a prov:wasStartedBy which had a range of Element (ie.
both Activity and Entity) - but then it could no longer be a
subproperty of prov:wasAssociatedWith - the DM3 specifies that
wasStartedBy and wasEndedBy are specialized forms of
wasAssociatedWith.

Therefore the corresponding prov:Start and prov:End should also be
subclasses of prov:Association - their attributes would also apply to
wasAssociatedWith.


To mirror the involvement of prov:wasStartedByActivity I've made
prov:StartByActivity which is a subclass of ActivityInvolvement.

I've updated the OWL to match this.
