other programs to build the database for you

Nobody releases that kind of information. Reverse engineering it is tricky at best, a minefield of litigation at worst. It can even be quite amusing -- a particular music management application (not ours) used the name of one of their programmers XORed with the data to 'encrypt' it . And they keep changing the damn things.
