This way (import everything with funny tagging and let users then work 
with it) is, in my eyes, suitable if you have reason to believe that a 
lot of what you import is actually going to be used. If, on the other 
hand, it is likely that 80% of what you import will later be deleted 
because it was there already, then it may be better to run the import 
like we did the Nordrhein-Westfalen import: Set up a completely separate 
WMS layer that can be shown in the backgroundd and allow people to 
import individual objects where they think it's worthwile.

Bye
