Matthew, (01)
To the extent that you understand Barry's BFO, could you say which
parts of 15926 cannot be mapped to it? As far as I understood it,
BFO was not bicategorial in the classic sense but rather as Barry
says, where one can switch between 3D and 4D views. I am familiar
with 4D approaches and some of the thorny issues wrt 3D, but your
reply on this would be helpful to we who are trying to make sense of
your (and Barry's) position. (02)
