TheOpen Database License (ODbL) is acopyleft license agreement intended to allow users to freely share, modify, and use adatabase while maintaining this same freedom for others.[2]
ODbL is published byOpen Data Commons, which is part ofOpen Knowledge Foundation.[3]
The ODbL was created with the goal of allowing users to share their data freely without worrying about problems relating to copyright or ownership. It allows users to freely use the data in the database, including in other databases; edit existing data in the database; and add new data to the database. The license establishes the rights of users of the database, as well as the correct procedure for attributing credit where credit is due for the data, and how to make changes or improvements in the data, thus simplifying the sharing and comparison of data.
TheOpenStreetMap (OSM) project completed the move from aCreative 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.[6]
Other projects using ODbL includeOpenCorporates,[7]Open Data Blend,[8]Open Food Facts,[9]Paris OpenData,[10] andOverture Maps.[11]
