Ich kann es nochmal from scratch machen. Danke für deine Hilfe :)

Tatsächlich hatte ich gedacht, das der Weg mit highway=steps (osm.org/way/1395553456) reicht, aber ich verstehe was du hier meinst.

Ich habe auch gemerkt, das surface=paving_stones teilweise nicht korrekt war, zum Beispiel Friedrichplatz soll surface=sett sein, und deswegen die Löschung. Aber im Rückblick vielleicht surface=paved wäre besser, aber ich könnte es mit surface=paving_stones lassen und einen Hinweis machen

Meinst du, dass es eine Fläche mit area:highway=pedestrian gab, aber ohne einen Weg mit highway=pedestrian drin? Ich habe meinen Changeset jetzt geprüft, aber ich könnte das nicht finden.

Und ich war dort vor Ort, aber nur einen Tag :)

In my opinion, the roads on the island should be tagged as normal roads (i.e. highway=residential/unclassified/tertiary) but just be tagged with motor_vehicle=no (and snowmobile=yes since snowmobiles are allowed if i recall correctly)

Wieso war area:highway nicht angemessen? Hindenburgstraße ist wohl eine lineare Straße

I believe that earlier that the different lines where not particularly well signed, and thus that using the route as the name could be potentially confusing to end users. In any case, it seems like there is more signage being installed, so it might be better to use the line name as the name of the ways now.

One other thing that came to mind, however, is trails which (very closely) follow a road. (for example, North Menomonee River Parkway between Burleigh and North Avenue) A user receiving a navigation prompt to follow "North Menomonee River Parkway" might be more useful than following "Oak Leaf Trail Menomonee River Line"

Also, btw, we are not the first people to have this discussion, for example there was this thread in the forum: https://community.openstreetmap.org/t/trails-use-name-and-or-hiking-route/110106
I'd rather not get to in the weeds about "what is a name" as usually OSM is best when there are practical, understandable solutions

Most of the changes are based on the classification guidelines that I drafted: osm.wiki/Wisconsin/Highway_Classification
which in turn was based on osm.wiki/United_States/2021_Highway_Classification_Guidance

Do you mean this park outline: osm.org/relation/6431116 ? As far as I can tell it represents the name of the "park" that this part of the OLT is contained in, and actually is not the bike trail itself. In fact, "East Side Bike Trail" is listed as a park on the milwaukee county parks website: https://county.milwaukee.gov/EN/Parks/Explore/Find-a-Park

And yes, I do find this confusing, but mapping can be confusing sometimes :)
