Would you mind explaining your intended use. Since this is not clear, I'm
not sure what would be an opening database.

Well then I can ask, at what point does an opening seize to be an opening
and become a game. If you are only looking for ECO openings, SCID already
has an ECO browser with an extended set of ECO openings. If you want more
than that it sort of becomes more like having a games database. Once again,
how you intend to use it determines what you want.

When I started to use SCID many years ago I was looking for the same thing,
and found a massive PGN base on Bob Wyatt's Crafty ftp site. I think it is
used for Crafty's opening book. I don't know if it's there anymore. I ended
up never using it because I realized after a while that it is not really
useful for a human as much as for a machine.
