Morning Denis

First thanks for your reports and great blog posts! I read everyone of them.

And second it's great to see the progress you're making.

Probably you could go to #kde-sysadmin on IRC and ask there. Would be great to 
have your code in KDE repositories asap.

What's the status of other languages than english? Does your parser already 
work with French, German, etc.?`If not what's missing or needed?

What about a search application for Nepomuk. Not inside Dolphin or krunner but 
a separate application with structured result display. But I think this is too 
much work for 8 weeks and probably not the right thing...
