<p>Well IMHO none of this is relevant, as we do not claim any rights
in individual elements in our database. <br>
</p>
<p>As a result every single operation for itself is completely OK.
The issues start when you (and I include any method of work
splitting in that) do any of them systematically in a way that is
no longer insubstantial. <br>
</p>
<p>Any data you directly created yourself remains yours naturally
and while there is a bit of fuzziness around the question of what
applies to the copy in the OSM database itself, you can do with
that what you want (assuming you weren't creating something that
depended on already existing OSM data).</p>

<div>Time to open up a whole new fresh

Call me werid, but I like the idea of
cooperation between opendata projects,
but differences in licensing don't make
this exactly easy.<br>
<br>
</div>
So here goes.<br>
<br>
</div>
Let's start with a node.<br>
</div>
<div><br>
</div>
<div>a)<br>
</div>
I add a node (say for a school) to OSM. Since
it's coming from an import (or I surveyed it
myself) I have more details and I'd like to
add those details to wikidata as well.<br>
<br>
</div>
I look at the imagery and find the school
grounds and place a node somewhere in the
middle. So I'm the one who determined the
coordinates. If I want to share them to wikidata
that should be fine. In the reference field of
wikidata I create a source reference "reference
url" and set it to the url Ctrl-Shift-I sends me
to <a
href="http://www.openstreetmap.org/node/12345678"
moz-do-not-send="true">www.openstreetmap.org/node/12345678</a><br>
</div>
<div><br>
</div>
<div>b)<br>
</div>
Next case I draw a polygon around the school
grounds and have JOSM determine the center point
for the coordinates. This time I use <a
href="http://www.openstreetmap.org/wat/12345678"
moz-do-not-send="true">www.openstreetmap.org/wat/12345678</a>
as the reference url.<br>
</div>
Again, I'm the one who determined the coordinates at
the time of creation of the object on OSM.<br>
<br>
</div>
c)<br>
</div>
I find a street on OSM and want to add/update its
position to/on wikidata. I take the 2 end points and
determine the center. This time I reference back to the
way on OSM, or if the way was splt, to the way segment
nearest to the center point. There is nothing there at
this point in OSM, usually the coordinates also don't
correspond to any OSM object. I was not the creator of
this street or its end nodes. odbl states I need to
state the source, that was done using the refernce url
pointing back to <a href="http://openstreetmap.org"
moz-do-not-send="true">openstreetmap.org</a>. Is this
enough?<br>
<br>
</div>
d)<br>
</div>
2 streets join on a node. wikidata has a property "connects
with". I'd like to use the url fo the node as the source for
the connection between these 2 roads. This time it's not
about the coordinates, but about the fact one can get from
one of those roads to another using that node. Is that OK to
do, or should I find anoher source for this 'knowledge'.<br>
<br>
</div>
e)<br>
wikidata also has properties "coordinate of northernmost
point" (easternmost, southernmost, westernmost). Can those be
sourced to OSM (nodes)?<br>
<br>

Polyglot<br>
