<div dir="ltr">Rory, I agree with you - there are always corner cases. And while we concentrate on the geographical aspect (e.g. "somewhere there might be a large territory where the tags mean different thing"), the corner case can actually exist in our own neighborhood, simply because our neighbor understood some tags to mean something different.<div><br></div><div>To use the a handball vs team_handball example - if it wasn't for you, no one would have been aware of such a distinction, and if we had a @talk discussion of the global bot autorename to fix it, there is a good chance it __might__ have been overlooked, and damage would be done - we don't have as many people monitoring @talk, as we have actually mapping things. But if someone made a challenge to convert handball->team_handball, someone would have caught it in your area, thus flagging the issue globally, documenting the distinction, and cleaning up the other areas where having a mix of both values is incorrect.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Oct 17, 2017 at 8:29 AM, Rory McCann <span dir="ltr"><<a href="mailto:rory@technomancy.org" target="_blank">rory@technomancy.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">On 16/10/17 19:49, Tobias Zwick wrote:<br>

Except.... that's not true. In Ireland "handball" is Gaelic Handball¹<br>
which is a one-on-one game, not a team sport (which is apparently a<br>
different thing²). There are some sport=handball's tagged in Ireland.<br>
Now the tag is clearly wrong, and we need to figure out something about<br>
that. But if you just change sport=handball to sport=team_handball, then<br>
you've entered incorrect data, based on incorrect assumptions.<br>

<br>
Good catch. So, it is no good as an example for that. But no matter, I<br>
think the idea got across anyhow.<br>

The idea that automated edits and tag replacements on a worldwide scale are a bad idea and might have edge cases you've never heard about? 😉<span class=""><br>

Not really. We have editors, and what they do, map styles and what they<br>
do, programmes like osm2pgsql and what they do. That's a form of<br>
"unwritten documentation".<div class="HOEnZb"><div class="h5"><br>
