But what if the source changes ? When I use high-resolution imagery to improve areas formerly mapped from low-resolution imagery, I change the source tag - i.e. from "Yahoo low resolution satellite" to "Microsoft Bing satellite". Since my edit is correlated with a change of source, shouldn't it be considered a break from being a derivative ?<br>

Yes it should be considered a break, because in that case you know what the<div class="yiv945059538im"><br>
source for moving the nodes was.<br>
</div></blockquote>
Good. Now do the license change impact auditing tools currently take that into account ? Should they only take the object's source tag into account or also mention of a source in the changeset commit comment ?<div class="yiv945059538HOEnZb">
<div class="yiv945059538h5"><br></div></div></blockquote></div>I think there may be a need to better understand how copyright works in this respect in the real world. <br><br>The location of individual nodes probably has no copyright component, however the shape of a way probably does [1]. If several people have adjusted the shape of a way then they most likely all have joint ownership of the copyright of the whole of that way [2].<br>
<br>Joint ownership is an important principle to understand. If someone edits a way then they are making a derivative of that way and inheriting *all* of the joint copyright ownerships. Even if their changes are to remove the effect of a change by one of the previous contributors it does not, as far as I know, delete that contributors copyright.<br>
<br>If this is true, then the only way to disinfect a tainted way is to revert back to the version prior to the infection and applying subsequent changes to that version. Simply negating changes does not delete copyright ownership because the ownership extends to the whole work.<br>
<br>Does anyone know of any precedents that show how copyright, once gained, can be deleted from a work?<br><br>80n<br><br><br>[1] Section 1 (b) (i) of http://membled.com/work/osm/Map_Project_Memo_public_FINAL.pdf <br>
