Good point.

Yeah, I might have been unclear, but IMO it'll shine for those apps.

Ah ok, well if you're going to provide subpar integration (basically only the 
bits for the file manager) sure that's enough. If you want to integrate it 
better if more than "we're done, we just depend on it". ;-)

Well, if you want to do it properly it'll require to patch our analyzers 
anyway. Actually I think that in the long run it's less work for us than 
using liblicense thanks to the benefits of using the RDF based facilities we 
already have (indexing for free, and neat api included). Otherwise, you patch 
the analyzers, then you have to make sure the info is available correctly 
through Nepomuk, and finally you have to make the wrapper API of the relevant 
liblicense parts for the applications to use. Looks like more work to me.

Well, I hope the rdf files will be shipped separately because that's really 
the part we need. Worst case if it's not shipped by distributions we'll be 
able to ship a private copy in kdelibs I guess.

Regards.
