This is nearly correct. What is missing is that resource types (and
creators) composed of 4 lower-case letters are reserved for the OS's use.
So you could use 'DATA', 'Data', or 'DatA', but not 'data'.
Also keep in mind that anyone could come up with a type that could collide
with yours, since there isn't registration of types, so you'd nearly always
want to also put your registered creator ID on the db (and check that it is
there when opening/searching) if you want to make sure that the database is
yours.
