Hi,
it's not common to add arbitrary strings (here: bicycle_tube) to keys.
The charge key can take multiple values for different use cases / items:

charge= 1 EUR/bicycle_tube; 2 EUR/brake_pad

So, the building is fine, but can't be used because the entrance road isn't usable? I.e. if this is will be blocked for a longer time access=no on the building and the road should be fine for the moment.

Hi,
the tag "skill rating=most difficult" is not used in any other place. Could you check the documentation of "sac_scale" or "mtb:scale" and see if these can be applied?

Nothing new to suggest or define here, that's an established use case, even supported by common presets in JOSM. See e.g.
https://taginfo.openstreetmap.org/tags/traffic_sign=DE%253A298
https://taginfo.openstreetmap.org/tags/traffic_sign=DE%253A293

I can only repeat what I wrote several times: Please don't invent new tags without documentation and discussion. This just makes the data inaccessible for anyone else who is not a human manually reading the tags on an object.

Hi,
welcome to OSM.
You dumped a huge amount of text on a dozen bus stop POIs. Please make sure that you only use proper tags as defined in your editor or the OSM Wiki. This is absolutely necessary to make the information usable by anybody else. Please also read the guidelines for imports of data:
osm.wiki/Import/Guidelines
as well as the guidelines for editing OSM as part of a larger project
osm.wiki/Organised_Editing_Guidelines

I think 'traffic_sign' is totally correct here. In most legislatures "traffic signs" are not only the metal plates on poles, but any type of road marking are defined in the same part of law and also named traffic signs.

I'd suggest to use 'traffic_sign' and in addition some kind of 'location' tag specifying its position and type, e.g. 'on_street'. In this particular case this is not even necessary, because HK:604 already is the code of a sign that always is painted and not on a physical sign.

I strongly recommend not to use road_marking:id. First of all, this resembles the syntax for tags in Indonesian language and second it seems to be based on 'traffic_sign:id' which was recently proposed and heavily downvoted.

Hi,
es hat mich auch gewundert, aber "service_provider" wird tatsächlich bisher nirgends verwendet. post_office:service_provider zusammen mit amenity=post_office hingegen schon 140 Mal.

Deswegen auch die Änderung - ansonsten bin ich aber auch eher der Meinung das Präfixe zu verzichten.

Hallo,
hast du die genauen Beschränkungen von diesem Parkplatz? Ich wollte die Tags auf das aktuelle Schema umstellen, werde aber nicht ganz schlau draus.

Hi,
could you check this way, it got a strange tag:
way/1287449797

Hi,
you added a "ruine" tag here - by mistake or on purpose?

Hi,
could you explain what this area represents? Right now it doesn't have any valid tags.

Hallo,
du hast hier viele neue, nummerierte Tags wie mapillary:8 erfunden. Das ist nicht nötig. Mehrere Mapillary-Bilder können (und sollten) in einem einzelnen "mapillary" Tag erfasst werden, getrennt mit Semikola.

Something went wrong here, all these objects don't have any valid tag.

The changeset is also missing the mandatory documentation of any import, see
osm.wiki/Import/Guidelines

Hi,
I found a strange "opening_hours:parking" on this pitch. Does that really mean you can park here?
way/36997839

Hi,
please check these buildings, they all got some strange "|ODS" tags.

Hi,
you added strange 'mv' tags across the world. Please check and fix.

Hallo,
solche POIs, die garantiert nicht wieder in derselben Form existieren werden können auch einfach gelöscht werden anstelle sie als "removed" zu markieren - in der Historie sind sie weiterhin vorhanden falls sich jemand jemals dafür interessieren sollte.

Hi,
there are some hundred ELVIS, REVERSED and RIVERSPLIT tags that made it through your import routine.

Hi,
I'm pretty sure I checked and saw that the address itself was already mapped. But maybe I misread one of the other ones. It was not my intention to delete valid house numbers.
