<div dir="auto">Dear Frederik Ramm and all other readers,
<div dir="auto"><br>
</div>
<div dir="auto">> If one person sees a horse and tags it
"kow" and then another person comes along and says "we all
agree that if something is tagged kow and not cow it is almost
certainly wrong" and changes the tagging, without noticing
that the thing is a horse and not a cow, then nothing has been
gained.</div>
<div dir="auto"><br>
</div>
<div dir="auto">I strongly disagree with your argument here.
Many of the objects I changed were still on version one or two
and had been for several years until I came along. Taginfo
usage and chaos theory suggest that as long as we don’t take
action, the numbers of color=*, building:roof:shape=* and
other duplicate tags only grow. With my changesets I am
effectively undoing the chaos that has been formed, which I
think is a valuable contribution to our ever-growing database.

<p>To be clear this has nothing at all to do with chaos theory, but
xkcd 386. <br>
</p>
<p>color is actually a good example of the use of a key slowly
decreasing over time after two peaks in 2013 and 2015 (the later
clearly due to an import/mechanical edit and 2013 maybe too). </p>

<div dir="auto">Adding to this, now the roof shapes, colours and
other attributes are more likely to be rendered, and if people
who look at rendering software (such as OSMbuildings) see that
the attributes of objects in their area are wrong, they are
more likely to correct them. Thus, to use your example, a
rendered “cow” will attract more mapper and user attention
than an unrendered “kow” and is therefore more likely to be
updated to the correct “horse”. </div>
<div dir="auto"><br>
</div>
<div dir="auto">Using ctrl+F to unify tags is something that we
should all embrace with the huge database that we are
maintaining. Your proposal to wait for local mappers to come
along and fix all of the millions of outdated tags there are
is not only horribly inefficient, but is also not a solution
at all, because most objects are only looked at once or twice
by local mappers, who are in many cases also unaware of or
uninterested in OSM-wide tagging conventions.</div>
<div dir="auto"><br>
</div>
<div dir="auto">> If you think that a simple
search-and-replace is a good idea – then leave your hands off
it and let someone fix it who has the time and energy to do it
properly.</div>
<div dir="auto"><br>
</div>
<div dir="auto">DWG member or not, what counts as “proper
fixing” is not for you, but for the community to determine. If
it were up to you, then ctrl+F would be removed from JOSM and
the community would lose a powerful mapping tool. That mindset
is harmful to the development and long-term sustainability of
OSM and I strongly disapprove of it. </div>
<div dir="auto"><br>
</div>
<div dir="auto">As I stated previously, we cannot keep looking
at the mess in our project, ignore it and then blissfully
continue to micromap the local playground. We need to start
showing some agency for the larger issues. </div>

<p>You are massively overstating the effect of typos in tagging, not
only are the numbers small (and due to the increase in preset
based tagging decreasing in occurrence), but further typos tend
to simply lead to the tag being ignored aka simply having no
effect.</p>
<p>Just to give a rough example there are ~470 million buildings in
OSM, even if all 6'000 color values that you fixed on ways had
been on buildings (a rough glance would indicate that irl there
were far less), we are talking about a tiny effect, even if we
look just at buildings with building:colour tags (less than a
million) we are still talking less than 1%.</p>
