The Open Database License (ODbL) is a copyleft ("Share Alike") license agreement intended to allow users to freely share, modify, and use a database while maintaining this same freedom for others.[2]

ODbL is published by Open Data Commons, part of the Open Knowledge Foundation.[3]

Notable uses[edit]

The OpenStreetMap (OSM) project completed the move from a Creative Commons license to ODbL in September 2012[4] in an attempt to have more legal security[5] and a more specific license for databases rather than creative works.

Other projects using ODbL include OpenCorporates,[6] Open Food Facts,[7] and Paris OpenData.[8]
