Thanks =)
I know it's pretty much only volker from the pimsters working with nepomuk  
(AFAIK).

I just figured out what exactly happens together with sebastian.
It's not nice what the feeders do atm. but it should work as long as there  
are no
other apps trying to access the same resources using the Resource api (If  
somebody does,
and isn't lucky, data will be duplicated on every change of the item)
I'm thinking about a fix for the data duplication issue, just in case.

So we'll just leave it at that for the first release I think, and make the  
rewrite afterwards.

Unfortunately I'm not aware, where in kdepim and how nepomuk is exactly  
used,
so it's a bit difficult to guess the consequences.

yes, we'll have to port them to the new nepomuk datamanagement service,  
which will be available from 4.7.
Only then we can actually start to use the generated resources actively,  
e.g. from MindMirror.

Of course, the copy with the emailfeeder in kdepim will need the same  
procedure.
