This change affects the two pipelines way/54630411 and way/54630411 which have now the tag substance=fuels set. This tagging is unique in the database. I'm going to change it to substance=hydrocarbons.

Thanks. Further discussion on OP's changeset comment in changeset/26201816

A part of the name Countrymark Finished Product Pipeline should not be part of the tagging. See changeset/53903841

For way/493835731 the typo in value "gravai" was corrected by deleting the whole substance tag. See changeset/53901206

For the way/308593417 substance=nafta was tagged. Does this pipeline contain
a) some kind of fuel ready to use for self igniting engines https://nl.wikipedia.org/wiki/Dieselolie
b) an intermediate oil distillation product https://en.oxforddictionaries.com/definition/naphtha
c) the North American Free Trade Agreement
Please discuss at the first occurrence of this value in change set changeset/26201816

Hi, you tagged "substance=a" for the Grünecker Straße with this change. The substance key is mostly used for the content of a pipeline. I assume that "a" means asphalt as road building material.

Thanks for the hint to the Wiki. I hope to find time to translate it to German.

The beef is in the second sentence: "… to make other systematic edits … without consideration of each change." Be assured that I invoked every way, checked it and it's surrounding and ONLY when not in doubt I changed something.

So my edits where indeed systematic but not automated because I considered the change.

I learn that I should
* make the affected areas smaller,
* limit the changeset to one to three values only and
* make better commit messages
to avoid disturbance in future.

Aside from that: Feel free to check my edits and point out which single mistakes I made :-)

Hi chilly,
please recommend a place (URL) to discuss edits like this. I will apply to that forum/board/mailling list and present the changes there.

Hi chillly,
thanks for your comment. Replacing "substance=sewer" etc. with "substance=sewage" did not seem appropriate for a longer discussion. Please recommend a place (URL) to discuss edits like this in the future.

Mit substance=groundwater erledigt.

Danke. Korrigiert mit changeset/51952209

Das mit dem älteren der beiden Wege hätte ich beachten sollen. - Persönlich gefühlt werden Geschäfte als Knoten besser von Suchmaschinen gefunden.

Die JOSM-Validitätsmeldung war:
Doppelter Weg übereinander

Auch bei den Gebäuderelationen hatte JOSM etwas gleb gemacht. Daher die Ändderung. Sollten nicht Geschäfte und Dienstleiter vorzugsweise mit einem Knoten getaggt werden?
