Personally, I would be delighted if we had more consistent naming rules, but with over 91,000 uses and three projects (according to Taginfo), a change is relatively unlikely.

I took the liberty of changing your entry RFI_name to name:RFI, as in addition to the language identifier (in lower case), there is also the spelling with operator (in upper case, also documented with the key note). Using the operator in the prefix is historically correct, especially since the different prefixes of the key name would lead to confusion here.

Does this path not exist up to the node node/108119825?

Okay, da war tatsächlich etwas unsauber. Ich hätte aber eher noch eine Verbindung zwischen node/9983619288 und node/99836773 66 vorgeschlagen. Da Du mit iD arbeitest, kann ich die Feinarbeit gerne übernehmen.

Welcome to OSM! Your changes have damaged the existing data to such an extent that I had to completely undo your changes and re-enter the data based on your sparse information. Please make sure to work more for the community when making your next changes.

Willkommen bei OSM! Nachdem Luftbild (und nachdem ich die Strecke gestern erst gefahren bin, halte ich Deine Änderung für falsch. Du vermittelst den Eindruck, dass Du von der Hettschädter Steige kommen, sowohl nach rechts, geradeaus und links fahren könntest. Das einzige sinnvolle Fahrmanöver wäre ein U-Turn wieder zur Hettschädter Steige, was technisch nicht möglich ist. Was ist Deine Begründung zu Löschung.

We do not need to store the area of a surface, as it can be calculated. Nevertheless, there are keys such as area_ha or area_sqkm that can be used instead of the foreign key UArea. Please do not use the key area, as it is a pure Boolean value (yes/no). For the population, there is the key population, and for the date of recording, there is population:date. Please note the OSM notation for the date here.
If you need help correcting the data, please let us know.
