Could either of you perhaps expand a bit about what you > mean. The value of the "building" tag would always be a type of building, such as building=house, building=apartment_block, building=shed, etc, but never building=entrance, because "entrance" is not a kind of building. Likewise, the value of the "entrance" tag would always be a kind of entrance, such as entrance=main, entrance=service, but never entrance=subway, because subway is not a kind of entrance. To show an entrance to a subway... depends on which country's English you're using: for the American sense (underground light railway), you'd outline the subway station, and mark one of the nodes of that outline as being an entrance, with entrance=yes or entrance=main. For the UK sense of subway (underpass, for pedestrians to cross a busy road by going under it in a tunnel) I guess you could mark the subway with a way, and tag the nodes at each end of the way with "entrance=yes", and tag the way itself to indicate that it is a tunnel; but that seems implicit anyway. __John _______________________________________________ Tagging mailing list [email protected] http://lists.openstreetmap.org/listinfo/tagging
