Nominatim

Nominatim (from the Latin, 'by name') is a tool to search OpenStreetMap data by name and address (geocoding) and to generate synthetic addresses of OSM points (reverse geocoding). An instance with up-to-date data can be found at http://nominatim.openstreetmap.org. Nominatim is also used as one of the sources for the Search box on the OpenStreetMap home page and powers the search on the MapQuest Open Initiative websites.
