What is the Clad Genius database structure in cafw.fdb?

Question

Clad Genius internally uses a Firebird SQL database (cafw.fdb). I can connect to it using the Linux Firebird client, but what are these tables:

SQL> show tables;
       BP_ADCAT                               BP_ADREG

Answer 1

The first few characters seem to be namespaces,

BP is Back Page
CL is Craigslist
KI is Kijiji (A Canadian classified)

I'm not yet sure what CA or GR are.
