This is a somewhat special case; normally, an admin boundary will be backed by a multipolygon relation, and at least hereabouts (.de) we tend to simply stuff the coastline into the admin multipolygon. So you will have *no* extra "boundary=adminisdtrative" way along the coast - just one single way tagged as coastline, which also happens to be a member of the boundary relation. (People tend to create one "landmass" relation that goes only up to the coast, and one for the national boundary which includes a 12 mile zone or so, but that's another matter.) In our neck of the woods, a typical example for two ways sharing the same nodes would be a road with a tram line on/in it. We do not create one way that has both highway=residential and railway=tram (because then, if the way also had a ref=, name=, or oneway=, would that refer to the tram or the street?) - instead we have two ways using the same nodes. And to the OP: Das haetten Dir die Leute auf talk-de auch erklaert ;) Bye Frederik -- Frederik Ramm ## eMail frede...@remote.org ## N49°00'09" E008°23'33" _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
