Hello, Short version: I think data licensed under CC-BY-SA 3.0 cannot be put under ODbL without written authorisation by the copyright owner. Can you confirm this?
Long version: I'm currently discussing with the copyright owner of a large database. They are a non profit organisation and want to release their data under a permissive licence to help integrate it in OSM or other projects. I suggested them to use ODbL but they would prefer CC-BY-SA 3.0, saying that it is compatible with ODbL as the following human-readable version of the license mentions "similar" licences: http://creativecommons.org/licenses/by-sa/3.0/ IMHO they are mistaken: I believe data licensed under CC-BY-SA 3.0 cannot be put under ODbL without written authorisation by the copyright owner. Can you confirm this? I would suggest them to release either under ODbL or under both ODbL and CC-BY-SA 3.0 (I think they have ruled out more permissive licences like CC-BY, CC0 or public domain). What do you think? Thanks, Mayeul _______________________________________________ legal-talk mailing list legal-t...@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
