 Hi Adam,

No problems. There are of course additional requirements, but the main
issue with mnesia is that I would like to be able to build the data store
from fragments that are precomputed inependently from each other, without
needing to import them or something like that. These fragments can be dets
tables or even simple files (one per entry), with the in-memory table just
keeping references to them and sometimes computing and adding new ones.

best regards,
Vlad
