Note that OS have not changed to the (UK) Open Government License but incorporated it:


At OpenStreetMap, we are concerned about the extra requirement for down-stream attribution and whether it conflicts with ODbL 1.0's Produced Work provisions, i.e. could the creator of a Produced Work be deemed to be an OS sublicensee.

"You must always use the following attribution statement to acknowledge the source of the Information : 'Contains Ordnance Survey data  Crown Copyright and database right 2011'"

No problem for OpenStreetMap, but

"The same attribution statements must be contained in any sublicenses of the information that you grant, together with a requirement that any further sub-licences do the same"
