Hello Erik, What do you mean by "to constrain additional triples to certain vocabularies" ? By 'additional triples', do you mean those that do not match anything mentioned in the constraint ? That is, if the constraint is something like :name String | (:firstName String, :lastName String) then is it the case that the additional triples are all those whose property is different from :name, :firstName and :lastName ? By vocabulary, do you mean a set of IRIs allowed as properties for the triples ? If my guesses are right, then all this can be easily handled by shape expressions (and their bag semantics). Note that closed shapes are also handled.
