this should happen e.g. in module mycube/entities/airport.py,


class Airport(AnyEntity):
    __regid__ = 'airport'

    def printable_value(self, rtype, **kwargs):
        if rtype in ('latitude', 'longitude'):
            return XXX
        return super(Airport, self).printable_value(rtype, **kwargs)

So indeed definitely NOT in schema.py (where schema entities get defined).

I also think you should have a look at the views/igeocodable stuff.

Either you will find here something that already suits your need or some
place where to provide a generally useful patch maybe ...
