This is interesting. What defines a first order formalism then ? That it has
a complete deductive calculus ? (03)
Am I right that OWL allows quantification over properties via class axioms
combined with class descriptions ? (04)
So someone trying to define OWL FOL would have to be careful to stay in first
order logic because Properties are first class entities ? Would that be a
difficult problem ? (05)
