CC BY and CC BY-SA are not compatible with the ODbL because the ODbL is a fairly lenient licence that allows ways of re-using content that neither CC BY or CC BY-SA support. To be compatible with either of the CC licences we would have to -downgrade- the ODbL and not allow numerous common use cases (for example publishing maps derived from OSM on any terms the map creator wants to with essentially just an attribution requirement). I'm sorry, but that route is a non-starter. And given that the relevant restrictions in the CC licences were reaffirmed (and extended) with the 4.0 versions, it seems rather unlikely that CC will do anything about it from their side or that their stakeholders would support such change. In any case it would require a licence change by the WMF to any such compatible licence too, which again is unlikely to happen. Not to mention that regardless of licence fiddling, there is still the question of the provenance of the contents in WP and third party rights that always makes use in OSM questionable. In summary: I doubt that anybody is willing to embark on this specific fool's errand. Simon > > my2cents >
