When you sign up to OpenStreetMap you agree to license your contributions under the CC-BY-SA 2.0. The license includes sections like: "You must keep intact all copyright notices for the Work and give the Original Author credit reasonable to the medium" I happen to think that the openstreetmap.org website gives credit "reasonable to the medium" via Planet dumps, the history feature in Potlatch and viewing details for individual objects at /browse/* pages. But this idea that the state of how openstreetmap.org fulfilled parts of the CC-BY-SA at the time of signup somehow modifies what the licensor can expect sounds very dubious. I've never heard something like this argued in any license debate. It would be interesting to see what the Creative Commons lawyers think about this. _______________________________________________ legal-talk mailing list legal-t...@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
