I disagree. Axioms must be written in a
representation language, for example; and
comparisons with existing ontologies must involve
aligning the languages they are written in. it is
a mistake to think that comparisons can be
meaningfully made across different, perhaps
semantically incompatible, formal notations.
My understanding was that the person ontology was
intended to be able to represent all information
about a person that might need to be publicly
available or available to other agencies (such as
medical information). No?
