<p>Hi,<br>
</p>
<p>Any thoughts about this ?<br>
</p>
<p>Should we consider the dispusted=yes tag on boundary ways as a <i>de
facto</i> standard and uniformize a few borders ? Should we
create a proposal about this tag ?<br>
The borders data do not fit the doc and the statement from the
Foundation and are not really usable right now...<br>

Another related issue -- maritime disputed borders. In the case of Crimea,
the disputed border with Russia is over water, thus not showing clearly in
many renderings, and over land with Ukraine, showing as a solid line - thus
appearing to side with the Russian interpretation.
A while ago Paul Norman wrote osmborder tool to help with the disputed and
maritime border rendering [1]. His tool mostly uses disputed=yes . The big
problem with rendering was that multiple borders
(city/county/state/country) were all overlapping one on top of the other,
producing a solid line. Instead, when drawing there should always be just
one line with the lowest admin level.

<pre class="moz-quote-pre" wrap="">Hello,
There seems to be no actual consensus on the way to map disputed borders.
The statement from the Foundation
<a class="moz-txt-link-rfc2396E" href="https://wiki.osmfoundation.org/w/images/d/d8/DisputedTerritoriesInformation.pdf"><https://wiki.osmfoundation.org/w/images/d/d8/DisputedTerritoriesInformation.pdf></a>
recommend to map the border that "best meets realities on the ground" but
it's not what is actually in our database:
See for instance :
<a class="moz-txt-link-freetext" href="https://www.openstreetmap.org/#map=12/45.8481/18.8378">https://www.openstreetmap.org/#map=12/45.8481/18.8378</a>

Both borders (according to Croatia vs according to Serbia) are mapped.
The same between Soudan and South Soudan:

In some places, there are boundary=disputed or dispute=yes on the boundary
ways, which is very convenient for a map-maker to know that there is a
dispute on these border and that you may want to render it with a different
style (or use another source).
Should this practice be generalized on all disputed borders or at least
submitted as a proposal ?
