Currently there is a lot of debate over licenses, some people want to change from cc-by-sa to odbl and yet others keep pushing for things to go to public domain.
I was chatting with one such person in favour of PD on the phone yesterday about this, one thought that occurred to me was to have data tagged with license information, editors could potentially go about this in a number of ways, explicitly tagging nodes, ways and relations with the license chosen by the user, eg data:license=public_domain, and warning PD advocates if they edit CC-BY-SA/ODBL information and that the changes won't be public domain. When a person explicitly wants ODBL/CC-BY-SA the license could be updated or stripped if it matches the OSM default. Alternatively the changeset could be tagged, but this would be a lot more difficult for editors to "know" what is PD and what isn't if the changeset contains a mix of both. While I personally favour a share alike type license, some don't and this might be a way to make the majority of people happier. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
