Thayt is the worst thing - now you don't know who will agree to new license and who don't (unless you have some magic crystal ball). So you don't know which data are going to be removed and how much of them would it be until the last moment. You can only guess or estimate that, though once we start gathering consent for new license, we'll be having lower bound for the estimate - we will know for some data that these will stay there for sure (data for people wioth consent for new license) and the rest maybe yes, maybe no. I thought of one improvement - in addition to allowing people to consent to new license, allow them also to (completely voluntary) agree to Public domain their contributions. Some of the people on wikipedia (though not nearly a majority) does that for their contributions and many photos on wikimedia commons are under PD, so I assume some contributors may like it here too - then give them the possibility. Some tools to extract only PD subset of data could be added later if necessary (export list of users agreeing to PD would make this possible). And as wikipedia offers their complete dump with entire history, we maybe can offer planet dump with entire history in it too, so it could be easier to pick up only the PD contributions (or basically to dig through history for any reason without querying the main server) Martin _______________________________________________ talk mailing list talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk
