The tag building=carport is used for is used for one carport building. The carport might provide more than one parking space.
Rationale: A carport is distinctive enough from building=garage and building=roof so that an own tag should be used. The plural (like building=garages) is not defined since all wide carports I could find can be classified as one structure. The key building=* is used since a carport is a type of building=roof. Add amenity=parking/motorcycle_parking/bicycle_parking + building=carports to mark the parking facility. If there are multiple carports at a parking site add the tags to an area surrounding them. These tags are usually not necessary for private parking. https://wiki.openstreetmap.org/wiki/Proposed_features/carport_buildings Regards Joachim (Jojo4u) _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
