The downside of not requiring copyright assignment is that OSMF can't sue for copyright infringement of the data. I think the plan was to use some very liberal license for the data (as opposed to database) which would not let them sue for copyright infringement anyway, because the license basically can't be infringed? But if the foundation wants to have copyright in the data I think it's trivial for it to have some by doing *some* of the maintenance edits on behalf of the foundation or one person (or more) transferring their rights instead of everyone doing this. Out of curiosity, could the license at all work if contributors didn't have to assign copyright *nor* database rights?

One of the claimed problems with CC-BY-SA was that users were worried that they could be sued by any contributor for copyright infringement. Aside from any can the data have copyright rights questions, if OSMF was to claim some copyright in the data then they're basically implying that other contributors do too, and anyone of us could sue users. Which I don't think is what they want. Out of curiosity, could the license at all work if contributors didn't have to assign copyright *nor* database rights?

Each time You communicate the Database, the whole or Substantial part of the Contents, or 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. [...] You may not impose any further restrictions on the exercise of the rights granted or affirmed under this License. however, as you point out, this doesn't cover the Contents. i guess it's possible take the stance that there are no rights inherent in individual Contents (as in the US) and therefore any attempt to impose an ND/NC clause on the Contents isn't valid. I may not have understood the meaning of the Contributor Terms properly, but clause 2 seems to waive any rights in the Content from the contributors and I haven't seen anywhere that asserts any additional rights, so am I right to infer that the Content is not constrained in any way? yes, in non-Substantial amounts i believe so. cheers, matt ___ legal-talk mailing list legal-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
