While it does none of these things, you may want to take a look at the 
hurry.query library anyway, as it defines at least a better way (in my 
opinion) to query the catalog. Contributions would also be welcome, of 
course. :)

The hurry library can be found here:

http://codespeak.net/svn/z3/hurry/trunk/

The query part is here:

and here's the documentation:
