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.
