hadMember(c,e) can't have additional attributes or other arguments. You could do something like: entity(d, [prov:type='prov:Dictionary']) entity(e1, [prov:key='k1']) hadMember(d, e1) This adds prov:key to the 'prov:' namespace, but that should be ok, since we've said Notes can do so. We could make it a little more specific to Dictionaries with "prov:dictkey='k1'". I'm also not sure what to do with multiple membership like: d = [(k1, e1), (k2, e1)] (Just give it two "prov:key"s?)
