That's actually not so difficult. I have changed how
some of the metadata is represented. This is not
so difficult to handle.

I will also remove some functions that I think were
a bad idea to begin with, and I will also change
the 'NULL' value to 'undefined', even though I
don't particularly like the idea (Erlang should have
proper NULLs).

I think a berkeley_db table type might fit the
bill here.
