[OSM-talk] Populated places: how to use is_in tag?

[Patrick Weber]

Agree it doesnt hurt to add tags. But what are the long term thoughts on 
administrative divisions inclusion in OSM ? I know from personal 
experience in the UK, that these are quite complex and differ not only 
in time, but also depending on what angle (administrative, census, 
electoral) you look at them.
