I have a question concerning produced works from an ODbL database, which people on this list may be able to help with. I'm not convinced that the ODbL is clear on this issue, so it may need to be addressed in the long run via the FAQ at http://opendatacommons.org/faq/licenses/ or even by amending the license itself. Because of this, I initially tried asking via the ODC contact email address, but was directed to this list instead.
I understand that if I create and then "publicly use" a produced work from an ODbL-licensed database I'm required to do various things. Roughly, I need to add some text to the produced work saying that it came from such a database (4.3), ensure that any derivative database created along the way is under a suitable license (4.4) and also meet the requirements for providing the final database or algorithm used to produce it (4.6). That's all fine. My question is about how I can then license that produced work to others. Are there any restrictions placed on what license I could offer the produced work under? I believe that I do not have to "share-alike" the produced work, and can keep it "all rights reserved" if I want to. (Although given the other provisions I have to comply with, others would be able to produce very similar produced works for themselves if they wanted to.) What I'm actually interested in is the other end of the scale: can I give the produced work away under a very liberal license? Do I have to do something ensure that other users and creators of derivative works maintain the attribution back to the ODbL database? Or could I offer the produced work under something like the CC0 license? This would seem to be quite an important question for ODbL data users, and I can't see any explicit statement about this in the ODbL itself. The closest thing is (4.3) where the text could be taken as a viral attribution requirement on any re-uses of the produced work. However it doesn't say that it applies to any derivative works arising from the produced work, it just talks about "the Produced Work" itself, though I suppose it could be argued that being exposed to a derivative of a produced work exposes you to some aspects of the original produced work too. Any thoughts on this would be welcome. Many thanks, Robert. PS: I've already tried asking a similar question on the OSM mailing list at http://lists.openstreetmap.org/pipermail/legal-talk/2012-October/007266.html . The discussion mostly got side-tracked by other issues, though here was some support for the idea that (4.3) imposes a viral attribution requirement. Even if this is the case, I don't think the ODbL is completely clear, so I think some form of clarification from ODC would be useful. _______________________________________________ odc-discuss mailing list [email protected] http://lists.okfn.org/mailman/listinfo/odc-discuss Unsubscribe: http://lists.okfn.org/mailman/options/odc-discuss
