- tony_cannistra 3y agoYou are mostly right, except that in addition to the same license, the Share-Alike provision in the OSM license (the ODbL [0]) also enables derivatives to be re-released with "A compatible license." I am not a lawyer, but I would assume someone at Overture has deemed their license (the CDLAv2 [1]) to be "compatible" with ODbL. (edit: From the link in OP, the OSM-based data is being released with ODbL. I think I'm wrong about license compatibility. Again, not a lawyer.).

- Doctor_Fegg 3y agoCDLA Permissive is not downstream compatible with ODbL. ODbL is a sharealike licence, CDLA Permissive (as the name suggests) isn’t. Overture can’t relicense OSM-derived content under CDLA Permissive. From a brief skim of the landing page, it looks like the OSM-derived content is not being offered permissively. See https://overturemaps.org/download/ https://overturemaps.org/download/.
- tony_cannistra 3y agoYou're right, I was mistaken.
- callalex 3y agoThese things don’t matter when one side has 100x the lawyers of the other side.
- matkoniecz 3y agoNot exactly. Are they releasing OSM data or OSM derived data on CDLAv2 anywhere, right now? There was issue like this in past but it was resolved.
