I must admit that I do not understand much. I thought importing data that was already under ODbL was the perfect case since it is the license of OSM. I have already imported <http://wiki.openstreetmap.org/wiki/Paris,_France/Buildings_Heights_Import> 2 years ago the height of the buildings of Paris which were also under ODbL license. I do not understand the problem for a possible re-licensing that would become impossible because of an ODbL import... while the entire OSM DB is itself in ODbL ! In short I am completely confused :) Otherwise I could ask an explicit permission to people who are behind the open data portal of Montpellier. But what should I ask them exactly? Thanks, Vincent.
