I'd also like an answer to that question. I did some experiments but
don't understand the way to get mnesia to play nice. I assume you have
looked at the way tripplestores are typically built with rdbms ? Some
of the schemes used in things like 3store, sesame, kowari (?) might
be translatable...

I am interested in working on this.
