Is it improper to have both on the same object? Of course not. it's usually lazy and not so good mapping to have buildings and stuff currently using these buildings, tagged together on the same osm object. In many cases you need a human to interpret which tag belongs to which entity (e.g. building or business). E.g. the tag "architect" normally will apply to the building, operator will apply in most cases to the business, name will likely apply to the business (because buildings often don't have names) but is already a highly ambiguous situation because some buildings do have names. address tags will apply to both entities (normally), start_date, wikidata, wikipedia and others will have to be discerned manually by humans, ... So yes, mappers use this style a lot, but it is (IMHO) more improper than proper. Another similar problem field are linear and area objects mapped together on the same osm entity, e.g. amenity=prison and barrier=fence on the same closed way. cheers Martin _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
