</div>Yes. The "OMR". Pass in a tile png with full path and the magic box<br>
reverse engineers it. Any network activity to <a href="http://openstreetmap.org" target="_blank">openstreetmap.org</a> is<br>
entirely coincidental. Hey, he is evil you know.<br>
<br></blockquote></div>The bar for creating a Produced Work is very low. As far as I can tell from the definition in the license [1] all you have to do is declare that something *is* a Produced Work to then be able to license as such.<br>
<br>Obviously you can create an image and license it as a Produced Work. Also fairly obviously you claim that a vector image (eg SVG) is a Produced Work, even if it contains most of planet.xml in unmodified form. Since the license sets no criteria or test for a Produced Work you can extrapolate this back to the point where a valid Produced Work is virtually indistinguishable from a planet file.<br>
<br>As it stands, this is not too much of a problem because the moment you try to operate on it the reverse engineering clause kicks in and you have the full weight of the ODbL applied.<br><br>However, if you exempt the reverse engineering clause for certain share-alike licenses then it becomes trivial to relicense the whole OSM database under such a license, you don't need OMR or any other complex process.<br>
