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
acronym.
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
the licence.
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.
