Sure. Plasma sprint.

Disable Nepomuk (System settings) and install Baloo. It should startup on 
boot, otherwise you can run the baloo_file process.
 
Most of the PIM side is already integrated, but the patches still have to be 
pushed. (I'll push them into a clone) I've started working on porting Dolphin,

There isn't a clear Resource API any more. There is a nice query API - take a 
look at baloo/src/core/query.h / term.h. There are some "examples" in the 
autotests directory.

It will remain hidden.

We may as well continue here.
