Please check this stream, something went wrong with the name tag:
way/330257036/

Hi,
what is the source of this data?
where can we find the required documentation of this import?

All these objects have a huge amount of foreign tags which don't look like they should be in OSM.

Please read and follow the Import Guidelines.
osm.wiki/Import/Guidelines

For now, I suggest to revert this whole import and start from scratch.

I just reverted another 60,000 objects of yours that are plain duplicates of existing ones.

Please NEVER load any data into JOSM without using the "Download" function from the menu. NEVER load data from files and upload them!

Hi,
you added the key "ref:udir_nsr_old". It's not common to add a "_old" suffix to outdated keys. Could you use one of the usual prefixes instead?
E.g. was:ref...

Ja klar, wenn es ein Fußweg ist, dann natürlich mit sidewalk statt cycleway.
"sidewalk:left:buffer" gibt es immerhin schon ein paar Mal in Toronto.

Es gab schon öfters Vorschläge/Diskussionen zu Sperrflächen als Tag an Straßen, aber da gab es nie eine wirkliche Lösung. Das Hauptproblem ist, dass solche Flächen auf viel zu viele verschiedene Arten daherkommen. z.B. die Lage muss man spurgenau angeben können, es gibt ja auch Fälle vor Kreuzungen zwischen den Spuren derselben Fahrtrichtung.

Hi,
please make sure you never upload objects with an @id tag! These will always be duplicates of existing objects created by loading data into JOSM from a file generated elsewhere. Always use the internal download options in the editor, never a geojson file!

Hallo,
bzgl. node/10595245841

Ich denke OSM ist nicht der richtige Platz um temporäre Umleitungen, die vor 6 Jahren für wenige Monate existiert haben zu erfassen. Die U49e dürfte nur wegen einer einzigen Baustelle überhaupt eingerichtet worden sein, und ist sofort danach wieder verschwunden. Ich kann außerhalb von OSM keinen Hinweis darauf finden.

Wenn ich das Luftbild richtig interpretiere, dann ist das einfach

way/5464620

cycleway:left:buffer = 5 m
cycleway:left:separation = no

Hi,
please check your edits, there are several ways with problems with their name tag, e.g.

name Chemin de la Ferme de l'Ile aux Oies = farmyard

Hi,
please check this node, it got a strange 'BCE' tag:
node/2329332643

Welcome to OSM!
Please note that all keys you use to identify an object needs to be in English -
everything else is not understood by the software and is not shown on maps.
Have a look to the wiki ( osm.wiki ) to find the common tags.

Reminder: Please make sure you don't use upper case letters in tags.

Hi,
welcome to OSM!

Please don't upload recorded tracks from your GPS to OSM. If you plan to add bus routes, please spend some time looking at routes that already had been mapped, and how this is done properly.

Please check all the tags you added, among others I found these mispelled ones:

showcase: lenght
showcase: length
showcase:lenght
Showcase:lenght
Showcase:length
Was:Name = boutique annie
Was:Shop = clothes shop

Please make sure you only use tags that are documented in the Wiki.

Hallo,
was heißt denn "barred"?
Gibt es da kein dokumentiertes Tag, z.B. aus osm.wiki/Berlin/Verkehrswende/Radwege

Hi,
you added "Height limit" tags to several ways. The correct tag for this is "maxheight". Could you have a look and change these?

Hi,
you added many tags to these objects that are not common and should not be in OSM.

In OSM we have to use a well-defined set of tags to allow all the software tools to understand the data and e.g. show it on maps.
Please use only keys that are documented in the Wiki or are available as presets in your editor.
Thanks!

Hi,
please be careful editing large multipolygons. This one has a huge number of errors in the geometry. Why did you add hundreds of rivers to it?

Hi,
something went very wrong here: You uploaded duplicates of hundreds of thousands of objects.

I'm reverting the full set of ~230k objects, all of them are duplicates of existing ones.

fernand ed, please always check before uploading how many objects will be changed / added and if this fits with the work you actually did. And: never try to load any data from a file to OSM and upload it. Always use the integrated download dialogue.
