<p class="MsoNormal"><span style="font-size:9.5pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-US">Good thing you’re cleaning up! The changeset is huge though, which makes it hard to review. It would have been easier if the work was split up into
different changesets, e.g. one for each type of change: “moving manufacturer and model from name tag to manufacturer and manufacturer:type tags” for one changeset, “adding generator:output:electricity=yes” for a second changeset and so on. That would also
make it easier to revert one of these big changes if something goes wrong or i fit is disputed.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:9.5pt;font-family:"Verdana",sans-serif;mso-fareast-language:EN-US">That brings me to the generator:output:electricity=small_installation key/value combination. This is not documented in the wiki (as far as i can see)
and to me, it doesn’t really make sense. I can understand that you want to identify smaller wind turbines, but I think the generator:output:electricity should not be used for this. Especially where you have changed an existing value in Watts (e.g. “generator:output:electricity=1800
W” into “generator:output:electricity=small_installation”), I think this is wrong. It takes away detailed information (the actual output in W). I can understand the motivation for this (filtering out small installations in queries), but I think this is not
the right way to do it. Especially for the turbines that had a value in W, I would suggest to revert these edits. I’m sure we can find a consensus on how to tag/identify smaller wind turbines. We can then document this in the Wiki and after that, we can see
where we should add to (or change) existing tagging.<o:p></o:p></span></p>
