</div>I personally think that this is taking things a bit too far; remember<br>
that to earn rights to something that is created, your contribution must<br>
be non-trivial. We must be very careful with these claims of "whose<br>
node" etc., because they will work the other way round as well and I<br>
would not be surprised if (for example) if you were to set very strict<br>
rules you could find that half of OSM actually belongs to someone else<br>
(for example, how exactly have the aerial images and/or old maps we use<br>
been orthorectified?).<br>

</div>It wouldn't be too late to do that, but we'd have to think carefully how<br>
the two projects could and should co-exist in the future. I.e. if I were<br>
to add data to the PD project I would like to add it to OSM at the same<br>
time, however if checking with OSM for duplicates will already bring on<br>
the "whose node is it" fraction telling me that I have now infected the<br>
PD version, that would then basically make it impossible for me to<br>
contribute to both at the same time and I would have to make a choice,<br>
which would be sad.<br>
<br>
Sure, it would be relatively easy to set up the same toolchain that OSM<br>
has on a parallel infrastructure, using the same editors, databases,<br>
renderers, just on a PD license. For the users it would be pretty<br>
transparent, you could basically switch from PD to Copyleft any time,<br>
using Copyleft where you just want to display something and using PD<br>
when you want to make a derived work. But it is going to be difficult<br>
for the editors.<br>
