+## Common Data Licenses
+Below is a table of common licenses under which datasets can be made available. A permissive license will likely permit more apps and developers to ingest GBFS data. No recommendation for any particular license is offered here.
+
+Definitions of terms:
+- Requires attribution: Data users must give credit (attribution) to the data publisher and provide a link to the license.
+- Share-alike (viral): Derivative works (remixed, transformed, or built upon the material) must be distributed under the same license as the original.
