Presumably the same thing that prevents the copyright on a DVD you copy off a TV screen from evaporating when you burn it back to DVD. (I mention copyright as BY is a copyright licence.) BY-SA is a more interesting case as the derivative work must also be covered by BY-SA. - Rob. _______________________________________________ legal-talk mailing list legal-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
