The ideal situation would be that the ODC licences are suitable, and that not just the Foundation, but everyone involved in OSM agrees. If that’s the case, then we can publish the new terms without significant loss of existing data. If there are major objections, of course, we will either withdraw the proposal entirely, or weigh up the dangers of retaining the existing licence against the potential withdrawal of data. We are hopeful that the ODC licences are sufficiently in tune with the “spirit of OpenStreetMap” that this will not arise, but need to be alert to the possibility.
if they did not have such an inept license, many things would be possible. good luck with the relicensing dudes
