Why does it have to be one exclusive_or the other ? Both what things are and what they are used for is important. There's normally always a way to tag both, even if the tags to do that can be a bit bysantine. New tags may want to focus on one aspect or the other, there's no hard rule. The highway tag is a poor example for the nature/use dichotomy. The interpretation differs by country (hopefully not within a country). Some countries place more importance on use (amount and type of traffic...) than on nature (surface, width...). Other countries adhere rather strictly to the national road refs, even if the road changes classification for purely administrative reasons (so neither nature nor use). What the highway tag is a good example of, is the organic evolution of osm's tagging system. One good example of nature vs use is church buildings reconverted to shops/pubs/tourist offices (all 3 can be seen in Dublin) and place_of_worships in various incongruous buildings. The building tag is now clearly documented as pertaining to the nature of things, but this hasn't always been the case and a lot existing building tags have dubious values. _______________________________________________ Tagging mailing list [email protected] https://lists.openstreetmap.org/listinfo/tagging
