I work on *yet another* application database[1] as part of Fedora package database [2].

We use very similar approach to get the data to store them and we fight the same issues.

For example now I'm working on better application detection as some packages (kdebase for instance)
contains just .desktop files for the most common applications. Also naming can be slightly different 
from release to release. This leads to confusing results like [3] or [4].

I like what you have achieved in your project and am interested in any form of cooperation.

I wonder how many other such project do exist...
