Which free chess database?

Sort:
Nobook

I would like to use a free chess database but there are so many of them:

1) JOSE

2) SCID

3) ChessDB

4) ChessX

Which one still has a continued development? There are 3 important things I would like to obtain from the database like the stats for each position, auto annotate my games and searching for a particular theme.

Jose hasn't been updated since 2006, and ChessDB since 2007.  I think ChessX may still be under development although I haven't checked lately.

One word: SCID.
