I know this debate. It is carried out by BSD'lers versus GPL'ers constantly and depending on what your respective definition of freedom is, each side can be right. There is just no universal answer what constitutes "free use". As a PD'ler I can tell you that I just want to avoid that we have to display a 1000 names of contributors in a corner of our map, that I would like to be able to overlay data on an OSM map without having to worry whether I am allowed to do that, etc. > The license cc by-sa is a good protection against that as it will > always allow osm to use derivate work of the original map. If you have ever looked at our legal list, you will have noticed that it is basically impossible to follow that license, that we don't even get it right ourselves. Nobody can tell you what will constitute a derivative work and what not. If you ask for permissive uses and the only answer you will get from the organization that produces the data "ask a lawyer, we can't/won't tell you", then that license is clearly not right. spaetz _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/cgi-bin/mailman/listinfo/talk
