- Gary: this sounds good to me. It would be an easy change to make and could even be rolled out in a level 2 maintenance release.
- Alan: A reasonable name change I suppose, though without any other changes it doesn't have any impact. I think you don't want to hide metaclasses, you want to know when you are using them, and how you are using them (and not use them in OWL-DL) And it doesn't address a more important problem, which is the whole ontological distinction between utilityClass/Things and physicalEntities, which is currently blurred. Given the terminal nature of BioPAX DX, and minor backward compatibility issues for little gain, I'd guess it makes more sense to take this up again as we begin work on the next level.
