light document management

I'm thinking writing a plugin (probably a combination of an action + a
formatter) to run a light document management system, keeping metadata in files.

Do you guys think moinmoin is suited for something like this?
I've seen Gallery and Gallery2, what I am thinking of is something more generic.

I'm also thinking of starting directly with moin2. How far is it from being
production?


Thanks.
