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.<ref name="ODbL1">{{cite web|url=http://www.opendatacommons.org/licenses/odbl/1.0/|title=Open Database License (ODbL) v1.0|publisher=[[Open Data Commons]]|accessdateaccess-date=2 July 2011}}</ref>

ODbL is published by [[Open Data Commons]], (seewhich also [[Open Data]]),is part of [[Open Knowledge InternationalFoundation]] (was Foundation).<ref name="ODC-About">{{cite web|url=http://www.opendatacommons.org/about/|title=Open Data Commons - About|publisher=[[Open Data Commons]]|accessdateaccess-date=2 July 2011}}</ref>

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 make freefreely use of the data in the database, withoutincluding worryingin aboutother copyrightdatabases; ofedit existing data in the creators,database; and add to thenew data orto usethe in other databasesdatabase. 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. Users no longer need to worry of repercussions of violations of copyright law or stolen information when using an Open Database License.
