It is about unfortunate fact such objects have no clear definitions - I had recent unfortunate case of somebody expecting clear definition of borders of Carpathians. In that case answer strongly depends on who and how defines Carpathians. For examples see https://en.wikipedia.org/wiki/Carpathian_Mountains with articles in other languages. Even basic facts like length and list of countries where this mountain range is located are different. OSM is not a proper place to store all possible definitions of "border of Carpathians" or pretend to have the perfect one. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
