We are running in circles here. Putting it on the building outline or the site outline/relation seems right, but doesn't work for multiple addresses on the same building/site. > > If there are multiple addresses for the same area one can simply > create multiple address-objects. You just said above that addresses are not features, but attributes. So what is an 'address object' and how can I create multiple of them? If you mean to create multiple building outlines to tag an address on each, we are clearly in the realm of 'one feature, one OSM element'. May I also add that, at least in theory, we are talking about a spacial database which should have no problem in determine which element lies within which other element. So an amenity node inside a building has an implicit relation to that building and could 'inherit' its address. So there is, again: in theory, no need for repeating the address on each POI. In the real world, we should of course just add that little but of redundancy because most data consumers and even our database are not that 'spacial aware'. I tried to find out what an address really points to here in Germany. I wasn't successful. You get a house number for a parcel of land, even without a house on it, but only if it is already connected to a street. When you build a house you definitely get one. Or the house inherits the number from the parcel. But you can get more than one number if you build multiple houses. (Or you can build additional houses without a number.) You can also get more numbers if you have multiple entrances to a building. But it is no problem for several flats in the same building to share the same number too. I couldn't find out on who's discretion this happens. And then there is the postal service, which some times even defines its own scheme when it for instance give a whole postal code range to a company, sets the address of a building to some street/city it isn't located at/in or delivers to mailboxes that are not in the same street then the buildings they belong to. my 2 cents, Chaos _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
