This may be tangential but why can't we just use the word involved to connect activities to all subclasses of QualifiedInvolvement? e.g.: :activity a prov:Activity; prov:used :in; prov:involved [ a prov:Usage; prov:entity :in; ]; you know what was involved by the type of the QualifiedInvolvement Paul On Feb 17, 2012, at 23:55, Timothy Lebo <lebot@rpi.edu> wrote: > As an RDFer, the following doesn't look too bad. > Ontology-ers will hate it (which is ironic, since they should only be worried about the axioms and not the tokens). > > :activity > a prov:Activity; > > prov:used :in; > prov:usage [ > a prov:Usage; > prov:?? :in; # <--- Suggestions for this predicate very much welcome! > ]; > > prov:generated :out; > prov:generation [ > a prov:Generation; > prov:?? :out; > ]; > . > > Short.
