If the processed datafile is used only by the program package, it belongs to
the program package, not to the data package.

/var/lib/<program-package>

If there is some tradition about having it under /usr/share you can
place a symlink there, also belonging to the program package.

Something similar is used by some ispell dictionaries (e.g. ipolish), 
allowing fine tuning of the hash contents building it from the postinst. 
That results in a new hash being built either at a new package install 
or at an ispell upstream version change. The new hash is owned by the
dictionary package, not by ispell, and located at /var/lib/ispell 
(with a symlink from /usr/lib/ispell in this case)
