As an adendum to that, I think the wording on the mian OSM page is incorrect. It contains the attribution, but the words here: Our CC-BY-SA licence requires you to “give the Original Author credit reasonable to the medium or means You are utilising”. Individual OSM mappers do not request a credit over and above that to “OpenStreetMap contributors”, but where data from a national mapping agency or other major source has been included in OpenStreetMap, ***it may be reasonable to credit them*** by directly reproducing their credit or by linking to it on this page. are not appropriate as they do not insist on the OS credit being retained in derived works.
