A tag which is meant to be exclusive of other primary tags. To avoid infinite recursion, amenity is a primary tag. > How should one know which tags are considered primary when parsing the OSM > database? It's a pain in the ass. You've gotta look through the wiki, look at the actual usage, and then take your best guess. It'd be a whole lot easier for parsers if we just used thing=fire_extinguisher/picnic_table/well/cable_distribution_cabinet/memorial/fountain/street_lamp. Or amenity=fire_extinguisher/picnic_table/well/cable_distribution_cabinet/memorial/fountain/street_lamp. How many of us even know, without looking, what the keys are for those 7 values? I just looked them up a few minutes ago and I've already forgotten two of them. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
