[OHM] OGL & OHM

[Jeff Meyer]

Copyright harmonization across a crowdsourced dataset is tricky, indeed.

Albin - is this the page you're referencing from MapBox:
https://www.mapbox.com/about/maps/
OSM actually has a semi-similar (and incomplete) page like that here:
http://wiki.openstreetmap.org/wiki/Contributors

Also, to be clear, we are talking about the UK Open Government License
<http://www.nationalarchives.gov.uk/doc/open-government-licence/version/3/>
& not the Open Gaming License
<http://www.wizards.com/default.asp?x=d20/oglfaq/20040123f>, correct? ; )

Albin, is it a definitive truth that the OGL and ODBL are incompatible? Has
anyone confirmed that providing a source reference on a wiki wouldn't
suffice for compliance? There are many methods of attribution. Has the OGL
been a blocker for importing (yes...) UK-based data into OSM?

Jerry's assertion that academic users will want a richer form of
attribution seems consistent with academics' need to be able to document
metadata provenance. My hope, however, is that we can encourage data
providers to get away from the NC provisions. Governments seem to be fine
with this, even if academics have yet to move that way.

Does anyone know of any good comparable systems where sources and copyright
restrictions are traced back down to the tag / metadata level? It would,
for example, be nice to be able to identify a subset of CC0 information
from within our data.

Thanks, Jeff
