[OSM-dev] Extracting just national boundaries

Hi Igor,

in my Europe extract from geofabrik (18-July-2011 00:49) France is such an example. In this extract I'm talking about the (top-level?) relation with id=11980 (which has a member relation with id=1362232, which in turn has several member relations).

Thanks for your help.
Greetings from Hildesheim,

hmm, I don't really know about member relation inclusion - and there's
no --used-relations task in Osmosis. Maybe that's a bug and should be
fixed... or at least investigated :)

Speaking of investigation: I did quite a bit of work with boundary
relations of Germany and I never encountered a problem with member
relations - simply because I didn't encounter this situation. Do you
have a specific example where it doesn't work so I could take a look at
it? At the very least, a country name whose boundaries you don't get
because of this, or a relation ID, or something like that?
