An information source I want to use (from the Tel Aviv municipality) has been released under the following terms:
“When using the information and databases, you must indicate the source of the information, and if possible link to this license.”
That is what their online license says, and when I emailed them asking to clarify our specific case, they basically referred me back to the license.

To fulfill these terms, is it sufficient to add an entry on ?

I would say yes, that would be enough. But I am not a licence guru or a suitable lawyer.

If still in doubt, ask at the OSM mailinglist “legal-talk” …
