Ah - I was going by <http://data.gov.uk/dataset/os-code-point-open> which seems to indicate the OGL is used. So that web page is not quite correct? >CC-BY-SA technically forces map makers to attribute each and every >contributor to OSM, ODbL does not. Is it at least possible to combine map data under ODbL with the Code-Point Open data to make a 'map plus postcodes' data set? I am guessing that the answer is no, at least not if you want to distribute that data. ODbL does not require attribution but it might be revised in ODbL 1.1 to allow an attribution requirement to be added by downstream users. Then it would be possible for users of ODbL-licenced maps to combine them with other open data that has an attribution requirement, although sadly such data could not be used to improve OSM itself. (As well as this postcode data set, another example of geodata with attribution requirement is the CommonMap project, a CC-BY licenced map of the world, which was partly intended as a common upstream which several map projects including OSM could take data from.) -- Ed Avis <e...@waniasset.com> _______________________________________________ Talk-GB mailing list Talk-GB@openstreetmap.org http://lists.openstreetmap.org/listinfo/talk-gb
