I think ideally there might be a frame-style modeled after MS (but including GCIs), and an axiom-style modeled after the functional syntax. It seems the most predictable way to do the latter would be to have a single object per axiom, and to use the non-terminals on the RHS of the production rules as names in the name-value pairs.

A direct transformation from OWL axioms to JSON would be much more
readable than first going through RDF.  There would be other advantages,
including size.
