I have to admit to being slightly confused about what licence a derived database can be published under. Clause 4.4a Any Derivative Database that You Publicly Use must be only under the terms of: (i). This License; (ii). A later version of this License similar in spirit to this License; or (iii). A compatible license. Clause 4.8 Each time You communicate any Derivative Database to anyone else in any way, the Licensor offers to the recipient a license to the Database on the same terms and conditions as this License Clasue 4.8 seems to me to render Clause 4.4a obsolete since the only way to have a licence on the same terms and conditions as this License would be if the text was word for word the same, unless of course 4.8 is meant to mean the same *spirit* as the terms and conditions as this License, but thats not what it says.. That would certainly seem a very good thing. In lots of peoples opinion where you *add* data, then it is good if that data can be shared back to the community.

Sharealike is meant to guarantee that the individual users of the produced work have the same freedom to work with the data as the person who produced it did. I suppose you mean that they get access to the producers own, up-to-then proprietary, data? If no data except publicly available databases under ODbL (such as OSM) or an ODbL-compatible license (such as SRTM) was used to create the derivative database, and subsequently the product, then individual users already *have* the same freedom as the producer. They, like the producer, can use these original, publicly available databases. And this will likely be the case for a vast majority of OSM-based products, if current uses of OSM are any indication. ODbL would be a lot less cumbersome if we could limit the share alike requirement to those derivative databases that contain unique data, i.e. are *not* calculated from public, ODbL compatible, data sources. Any gifts to the *project* that result from this freedom are a side-effect. You are right, share alike can work well even if no data ever flows back to the project. I shouldn't have neglected that aspect. But like the OSM community, other data users benefit primarily when they gain access to unique data that was not publicly available before. -- Tobias Knerr ___ legal-talk mailing list legal-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
Re: [OSM-legal-talk] Exception in Open DataLicense/Community Guidelines for temporary file
2011/7/1 Tobias Knerr o...@tobias-knerr.de: Most of these concerns could be alleviated by dual-licensing under both ODbL and CC-BY-SA. I'm not fond of the ODbL and would be happy with a CT + CC-BY-SA solution (it could achieve most of the declared aims of CT + ODbL and avoid most of the problems), but dual-licensing would of course be even more convenient from the perspective of a data user. Dual licensing has a really big problem for the project: 1) We release the data under CC OR ODbL 2) A third party uses data under only one of the licenses 3) Even if they are both ShareAlike, the transformations made by third party cannot be returned to OSM, as they are incompatible with unused license When Wikipedia changed it license from GFDL to CC, old texts remained also GFDL, but new ones are only CC, because of this. -- Jaime ___ legal-talk mailing list legal-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk

With CT + ODbL: 1) We receive data according to CT and release the data under ODbL 2) A third party uses data under ODbL, but does not agree to CT 3) Even if the data is ODbL, the transformations made by the third party cannot be returned to OSM without giving up one of the primary advantages of the CT, the ability to relicense without contributor veto. CT + CC-BY-SA isn't different in that regard. Generally, we have to accept that we can only take modifications back into to OSM if either * a third party cooperates voluntarily (= dual-licenses/agrees to CT) or * we accept to be limited to /one/ license for that data. The latter is relevant no matter whether we actually use different licenses at the same time, or just want to have the option to switch to a different license in the future without deleting data. -- Tobias Knerr ___ legal-talk mailing list legal-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
