Thanks Robert.

I see that the old OS OpenData Licence URL now redirects to OGL version 3 (
) and as such we can safely assume that the OS consider the licence dead.
Other UK agencies who have released data under this licence should update
their text accordingly, if this doesn't happen then a polite email to alert
them of the change would be encouraged. I see no reason to wait for this
change to be made prior to using the data in OpenStreetMap. We have a green
light lets not convince ourselves it's any other colour :-)

In terms of public rights of way released under the OS OpenData licence,
this means there is nothing blocking our use of this data. A ground survey
is still recommended though.
