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. And parallels even more nicely.
