An older version of the database is already available for download, but that's not the approach you want for common sense anyway, no one needs to remember that a "dog is not a cat".

I'd recommend that more people take a look and compare its approach against others. https://en.wikipedia.org/wiki/CycL is compact and worth a read, especially the concept of "microtheories".
