OpenStreetMap iD tagging schema overhaul

Improve OSM iD tagging to expand capabilities of OpenStreetMap editors

iD tagging schema is a machine-readable description of key-value parts describing OpenStreetMap objects. A comprehensive tagging schema allows normal people to contribute to this global data commons, and enables translation of descriptions. But there are known deficiencies to the tagging schema. This project will overhaul the OpenStreetMap iD tagging schema, and thus expand the capabilities of OpenStreetMap editors to create great maps.
