The iD Editor has some JSON metadata about this .. see : https://github.com/openstreetmap/iD/blob/master/data/deprecated.json example: { "old": { "highway": "ford" }, "replace": { "ford": "yes" } }, { "old": { "highway": "stile" }, "replace": { "barrier": "stile" } }, { "old": { "highway": "incline" }, "replace": { "highway": "road", "incline": "up" } }, [ + Wiki deprecated list : https://wiki.openstreetmap.org/wiki/Deprecated_features ] And the iD Editor has a lot of presets metadata : For example: Homeless Shelter === amenity=social_facility + social_facility=shelter + social_facility:for=homeless https://github.com/openstreetmap/iD/blob/master/data/presets/presets/amenity/social_facility/homeless_shelter.json { "fields": [ "operator", "address", "building_area", "opening_hours", "wheelchair", "social_facility_for", "internet_access", "internet_access/fee", "internet_access/ssid" ], "geometry": [ "point", "area" ], "terms": [ "houseless", "unhoused", "displaced" ], "tags": { "amenity": "social_facility", "social_facility": "shelter", "social_facility:for": "homeless" }, "name": "Homeless Shelter" } Imho: - The only problem, that they only accept general tags, for general mappers .. ( see https://github.com/openstreetmap/iD/pull/3600 ) Probably the other editors has a similar metadata ..
