It is a non-trivial problem, it does not make sense to do something every time for rendering that can be solved once statically in the DB and it will have to be implemented for every renderer in a different way as they have very different technical approaches. You are putting a lot of complex work into other peoples laps and make it sound very easy. It is not. You don't tag for the renderers, you tag to avoid ridiculous layout on the maps. And there will always be situations where a user expects a POI in a different place than any technical approach will give you. > Therefore, I think the current algorithm for the add-pois-to-areas is > sufficient, because it will correct most instances of those duplicate > tags, which are errors in the database and should be corrected in the > database anyway. I agree that if there is a POI and an area, probably only one of them should be named and only the named instance should be used. But if someone deliberately put an additional POI there for a reason, it is not an error in the db - your definition is just too simple. bye Nop
