    2121It appropriate at this point to bring in another idea, Reference Data.  When you have to relate abstractions between two representations, you really need a third.  (You can say that one of the representations is the abstract one, but usually leads to compromises you shouldn’t make.)  You need a third that truly abstracts the two representations.  If you increase the number of representations, it forces you to generalize that abstraction to cover all possible representations.
