This is a matrix for quickly checking compatibility of data released under certain common licenses with the ODbL. Please keep in mind that this is a community wiki page that can be modified by everybody and that it is intended to give you some guidance, but cannot substitute individual legal advice. The content of this page does not necessarily represent the views of the OpenStreetMap Foundation.

If you are interested in background information and past discussions regarding this topic, one possible source is the legal-talk mailing list archive.

Note that while declared license of dataset may be compatible there may be still problems due to different jurisdiction and/or ignoring copyright issues. For example, Wikidata declares itself to be CC0 but includes location data copied from Google Maps, OpenStreetMap and other copyrighted sources.
