Personal Video Database

Hi!

I don't know if anyone asked this before. If so, i am sorry.

First of all, i love PVD. It is the most complete application out there and it is free. I thank nostra for that.  

I am thinking about writing (in a near future) an application that needs to access PVD data. This application would be external to PVD.
I want to know if:

a) There is any documentation available (table diagrams?) or any api (stored procedures?) to directly access the pvd database.
b) Is there a simple way to write an export plugin? If so, can it be written in any other language than delphi (like c# or java)?

I don't need an urgent answer, as i am just planning to start this in the end of July, but i would appreciate any possible help.

Thanks
