The [http://www.opendatacommons.org/licenses/odbl/ Open Database License, "ODbL" 1.0], is an Attribution and Share-Alike license for Data/Databases. It has been developed by [http://www.opendatacommons.org Open Data Commons] with input from OpenStreetMap.
It offers clearer protection for OpenStreetMap and better clarity to end users. OpenStreetMap data is offered freely for any use under Attribution and Share Alike terms. One important difference to highlight is that we will no longer require maps made from our data to be released under Share Alike conditions. Instead, any license can be used, including commercial, as long as any enhancements you made to our data
