Wow. That’s quite impressive examples. I fully agree that this
Europe-centrism might lead to issues in the future. I remembered being
quite confused when I first read the documentation for crossing ways, as
they are all following UK’s naming system (which I’ve never heard
before). They are well-documented, so I guess that it’s fine. But I
understand what you mean: the “name” tag issue may not be the most
relevant in this family of issues.
This might indicate that the people discussing in this mailing list are
from a very specific background, possibly caused by the language of the
mailing list itself.
At the same time, I have to admit that I don’t feel like there are that
much pictures on the documentation. I was for instance surprised that
there was no picture for the “minimap” tag in the wiki (I fixed this in
the meantime ☺). So it might be something that we can easily improve
step by step ☺
I’m not sure what to conclude here. I guess that being conscious of the
Europe-centrism issue during discussions might help? Or that we may need
to look for volunteers to complete the OSM wiki with additional pictures
from non-Europe/North America? I will look at the pictures I took back
to been I lived in Chile and Brazil… but as I wasn’t into OSM then, I
won’t have much useful 😔
