If data is indeed offered for re-use under the Open Government Licence, then the answer is yes, you can use it in OSM. If you read to the end of the OGL, you'll find that it helpfully says: "These terms are compatible with the Creative Commons Attribution License 4.0 and the Open Data Commons Attribution License, both of which license copyright and database rights. This means that when the Information is adapted and licensed under either of those licences, you automatically satisfy the conditions of the OGL when you comply with the other licence." So you can be confident that if you have data under the OGL then you would have sufficient rights to allow re-distribution under the ODC-By licence, which in turn implies it's ok for OSM to distribute it under the ODbL. However, there is one potential problem in this specific case -- and that is whether or not Norfolk CC actually have the rights to distribute that data under the OGL. The coordinates in the dataset will almost certainly have been derived from an Ordnance Survey base map. If that's the case then Ordnance Survey claim IP rights in the data. While there is a procedure to allow councils to release such data, OS insists that it's released under OS's own variant of the OGL, the OS OpenData Licence. Unfortunately, this licence is probably not compatible with the ODbL, and hence we can't use such data in OSM. See http://robert.mathmos.net/osm/os-open-data.html and http://robert.mathmos.net/osm/prow/council-gis.html So before making use of the data, it would be good to get clarification from Norfolk CC about whether they own all the IP rights to the data and whether they are actually able of offer it under the OGL. If you're interested in Norfolk Rights of Way though, one thing that we can definitely use in OSM is the set of Definitive Statements that the council maintains. These aren't restricted by OS's IP rights, and we have permission to use them under the OGL. See http://robert.mathmos.net/osm/prow/norfolk/ . Robert. (On the subject of confusing licences, I've long said the OSM's Licence Working Group should maintain official lists of "OSM compatible" and "OSM incompatible" licences that they've reviewed, in order to save mappers continually having to ask these sorts of questions and deal with legal interpretations themselves. Unfortunately, this doesn't deem to have happened yet.) -- Robert Whittaker _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk-gb
