This is perfectly possible. You cannot tag _the same key_ twice, but you can have different ones. "building=yes" + "shop=bakery" is perfectly valid. > I should point out that all of these building polygons has been tagged with > key=building If you mean by this what is usually meant by it, we have a major retagging to do. The way to tag a building is not "key=building", but "building=yes" To get back at your question: I would be against the second solution (using one of the nodes of the polygon. The polygon, if everything is correct, should denote the outer walls of the building. Only things that are actually on that outer wall should get mapped on nodes of that polygon. A shop would be extending into the building, so putting it on the outer wall would be incorrect. Putting it on the polygon would be correct if the shop and the building are indeed 'the same thing'. That is, there is not something else in another part of the building. Putting it on a node would always be correct (unless it is already put correctly on the polygon). My preference is not to put it at the entrance, but at the (approximate) center of the actual shopping area. > Another question.

One node one value I believe is the principal. It depends on what you mean by 'also operates as'. If it is really more like two shops in the same building, then put two nodes in. If it is one shop with a somewhat odd combination of articles for sale, choose one as the main one (a supermarket that has an extraordinarily large bread section is still a supermarket, a place where bread is baked and sold that also has a few shelves of other foodstuff is still a bakery). If you really cannot choose, use the semicolon as described in another answer, or consider it two separate shops and use two nodes. -- André Engels, andreeng...@gmail.com _______________________________________________ newbies mailing list newbies@openstreetmap.org https://lists.openstreetmap.org/listinfo/newbies
