[Tagging] Related: Antarctic territories

[Michael Krämer]

First of all I think there is no really perfect solution to the problem. To
me this is inherent to the dispute as different parties have a different
view of what's right and wrong. So I think this conflict will show up in
the data anyway.

I agree.

Ok, but I am personally quite hesitant to tag things in a way so Nominatim
gets correct results. After some checking with places in Israel and the
Palestinian territories I think Nominatim might not be the best benchmark
to use.

I do not consider adding the region to both countries to be a great
solution myself. It's just an pragmatic approach to get things covered
'good enough'. Ideally the disputed borders were marked as disputed and
rendered accordingly e.g. dashed instead of solid. Or event the disputed
area could even be hatched or so.

If we add 'controlled' or 'dejure' and 'defacto' this sounds good to me: So
the northern border of Abyei should be 'dejure' in Sudan and the southern
border 'defacto'. The South Sudan should have things just the other way (if
I got the legal situation right). Basically there is a section where the
border of both countries is not really well defined and for me the data
should reflect this.

I agree that for Antarctica my strategy of being part of both definetly
does not work. This is different and probably needs special treatment.

When working on the border beween Sudan and South Sudan I spent some time
looking into disputed borders. Some key observations for me were that (1)
there are more than one would expect and (2) there currently is no
established method of handling this in OSM. So I am happy if we find a
better solution but I guess this easily requires changes to some other
tools like the rendering or perhaps Nominatim. But this shouldn't keep us
from looking into it.
