As long as you: '''Attribute''', '''Share-Alike''', '''Keep open'''.<ref>{{Cite web|url=https://opendatacommons.org/licenses/odbl/summary/|title=ODC Open Database License (ODbL) Summary|date=September 12, 2009}}</ref>]]

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]] (see also [[Open Data]]), part of [[Open Knowledge International]] (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 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.

The [[OpenStreetMap]] (OSM) project completed the move from a [[Creative Commons]] license to ODbL in September 2012<ref>{{cite web|title=OpenStreetMap data license is ODbL|url=http://blog.osmfoundation.org/2012/09/12/openstreetmap-data-license-is-odbl/|publisher=OpenStreetMap Foundation|accessdateaccess-date=17 September 2012}}</ref> in an attempt to have more legal security<ref>{{cite web|title=Legal FAQ|url=https://wiki.openstreetmap.org/wiki/Legal_FAQ/CC-BY-SA_Archive#What.27s_this_about_a_licence_change.3F|publisher=OpenStreetMap}}</ref> and a more specific license for databases rather than creative works.

Other projects using ODbL include [[OpenCorporates]],<ref>https://opencorporates.com/info/licence</ref> [[Open Food Facts]],<ref>{{Cite web|url=https://world.openfoodfacts.org/data|title=Data|website=world.openfoodfacts.org}}</ref> and [[Paris OpenData]].<ref>{{Cite web|url=https://opendata.paris.fr/page/lalicence/|title=Open Data Paris|website=opendata.paris.fr}}</ref>
