Hi,
The handling of epd files in scid comes very close to what Aquarium does
with its databases. If I have an open epd it shows information associated to
the position on the main board.
But:
The epd window in scid is very basic. Instead of providing just a text field
it would be better to support just some epd field types (e.g. comment,
evaluation, search depth, best move) of the epd format and support them
better. I still don't know the semantic of the lower field, because I always
get an exception when I click on it.
Aquarium knows something like epd configurations, where you define that you
want to get comments from one epd file, evaluations from two others. The
result is shown in one integrated window as part of the main window.
You can copy from Chessok epd databases with the basic computer evaluation
of millions of positions. So the standard epd format is like pgn to exchange
information. An internal optimized format to work with amount of data is
necessary.
Once you have this you can write an algorithm, which uses an engine to
evaluate a position, stores the results in the epd, finds interesting
alternatives to the main line at any depth and continues there. The
evaluation of these positions then may change also the evaluation of the
initial position (alpha-beta calculations). With Aquarium you can run this
over night. The next morning you need something, which translates the
results into a readable format. For example it creates a normal game
notation from the initial position with all interesting alternatives as
variations. Then you can put your name on it and sell it to Chessbase :-)

This, however, sound quite similar to the way tree masks work in Scid...

This remains true, however.
