You're right, of course. BY-SA provides weaker copyleft than, say GFDL (this was brought up during the Wikipedia transition to GFDL). But that doesn't change the fact that ODbL provides even weaker copyleft than BY-SA. >> and because it requires distribution >> of source along with distribution of produced works. > > You have to share the database alike, you mean? ;-) No, that's not what I mean. > BY-SA 3.0 almost replaced the anti-DRM clause with a parallel distribution > clause.

So, your argument is that ODbL is comparable to something that CC-BY-SA 3.0 almost was? I have no idea if that's true or not, but it's quite irrelevant, as this is not horeshoes or hand granades. >>> Making mash-ups easier and not excluding incompatible data sources in >>> what >>> are now called produced works has always been a strong goal of the OSM >>> community that I've encountered. >> >> So you want to change the license (not just a flaw in the license, but >> an intentional feature of it).

How so? This may be how Cloudmade treats the data, but http://wiki.openstreetmap.org/wiki/Common_licence_interpretations says that mash-ups are generally required to be CC-BY-SA (with a *possible* exception for mash-ups where the layers "are kept separate and independent"). How you're supposed to create a mash-up where the layers aren't mashed up is, I suppose, left as an exercise for the reader. _______________________________________________ legal-talk mailing list legal-talk@openstreetmap.org http://lists.openstreetmap.org/listinfo/legal-talk
