Dear Anthony,

Not clear what the _ _ _ mean: empty parameters, maybe? Why do you want to have a role for conditions? And why should it be position specific?
Oh. I understand: terseness. Ok: you are suggesting a linearization around quoted triples that specifies in a specific order initial and final dates, geographical constraint and other types of constraint.
Cool. I like it.

No, this I would not appreciate. This implies adding many different predicates (:presidentOf, :monarchOf, :emperorOf, :dictatorOf, etc.) and a lot of description of how to use each predicate. I even repent using monarch (but wikidata made me do it), and would now rather use :headOfState or some such, equally used in all countries regardless of whether they are a monarchy or a republic or something else:
:Napoleon :role :headOfState "1804-05-18"^^xsd:Date "1814-04-06"^^xsd:Date :FirstFrenchEmpire
Ciao
Fabio
