My interpretation is that planet.osm is a new Derived Work each week and
could be made available on the latest CC-BY-SA licence, ie 3.0.
Would you suggest that the attribution on paper would be as follows?
"Map licence CC-BY-SA 3.0, details www.openstreetmap.org/licence"
The web version would link from CC-BY-SA 3.0 to
http://creativecommons.org/licenses/by-sa/3.0/ and it might be appropriate
to adjust the displayed text for the openstreetmap link.
Personally I think this is getting pretty crisp and practical. It does rely
on a few specific legal opinions that we would need to get checked out by a
real lawyer (as I mentioned in the previous post) and of course we can then
fiddle with the detailed wording until the cows come home which sounds like
Have I missed anything?

Make sure to include the licence version (e.g. CC-BY-SA-2.5). It's
probably easiest to link to the licence URL at Creative Commons, which
gives the version number as part of the address and explains the
It might be worth making a static "Licence" page on the osm site to
handle licencing and attribution. This would be the URL mentioned by
So you could just say:
Map licence, see: http://www.openstreetmap.org/licence
One thing that is worth considering is how to handle CC Licence
upgrades. The "upgrade clause" in the BY_SA covers only derivative
works. You could argue that an updated version of the OSM database is
a derivative, in which case this would make it possible to upgrade the
licence as soon as someone added some extra data, but IANAL so I'm not
sure about this.
