I don't know of any such attempts. I've always wanted such a database! An
obvious place to create it is on the nLab. I just started one:
http://ncatlab.org/nlab/show/database+of+categories
but it will only become interesting after a while.
If everyone here contributes an entry or two today, it will be interesting
by tomorrow!
