The changes are threefold:
1. Soprano in kdesupport is replaced 100% by Soprano2. Soprano 1 and 2 are 
neither binary or source compatible. Soprano2 introduces (among other) the 
sopranoserver and client libs which are needed by nepomuk in 2 and 3.

2. kdelibs/nepomuk: only internal changes which now use sopranoclient instead 
of the nepomuk middleware lib to access the data store. The API does not 
change except for one method in ResourceManager which returns a 
Soprano::Model instead of the middleware registry.

3. kdebase/runtime/nepomuk: For now an aditional dependancy on sopranoserver. 
I am planning to drop the dbus interface (base on the nepomuk middleware) 
later.

I hope this helps.

Yes, Soprano2 has a much cleaner API than Soprano1. At least that is my 
opinion. :)
