Hi Thomas, There is no requirement that tiles from osm.org be purged or relicensed when the data base is published as ODbL. ODbL permits Produced Works like png tiles to be licensed $notODbL, provided that the ODbL obligations are met. I expect that the map tiles at osm.org will stay CC-By-SA, as they are a Produced Work, and have a creative aspect. This simplifies several things, including, no need to purge all the tiles at once, and no need to have all tile consumers update their copyright information. That's not to say that OSM tiles will forever be served as CC-By-SA. That also does not preclude creating and serving tile sets under other licenses. _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
