</div><br><br><br></div><div class="gmail_extra">no, if we used only those open data that have no strings whatsoever attached to them (i.e. cc0 or public domain) we won't burden our db with attribution and share alike requirements that possibly will prevent the active users in the future to change the license.<br>
<br></div><div class="gmail_extra">If the data publisher has chosen a license with only attribution requirements and sees these satisfied by being mentioned on a list in our wiki this is quite as good.<br><br></div><div class="gmail_extra">
Share alike licensed data should IMHO not be imported into osm because it makes another license change practically impossible (at least not without data loss, and unfortunately not only the originally imported data but also everything built on it).<br>
