Hi,
please check the gas stations you edited: "fuel:fuel:diesel:class2" is a mistake and should be "fuel:diesel:class2"

Hi,
you added 'catenary_mast:support' here. Shouldn't that be "catenary_mast:supporting"?

I don't know how good the automatic translation is, but to me it sounds like you really need to sign up and it's not just "touch and go" like, e.g. in some public transport systems.
Maybe tagging it like this:

authentication:none:conditional = yes @ (Mo-Th 08:00-17:00; Fr,Sa 08:00-18:00; Su 08:00-13:00)

authentication:mobile_phone = yes

authentication:membership_card = yes

opening_hours = Mo-Th 08:00-17:00; Fr,Sa 08:00-18:00; Su 08:00-13:00 || 24/7 open "with login / id chip"

self_checkout:conditional = only @ 24/7; no @ (Mo-Th 08:00-17:00; Fr,Sa 08:00-18:00; Su 08:00-13:00)

Hi,
I think that there are several issues with the tags as they are. Maybe you can write a draft and put it up for discussion in the forums.

- "est:" is not used in any other context. It makes things rather complicated for both mappers and data users - they need to support tags with and without prefix and there is no clear rule when the prefix is needed. If it's an estimate can be part of the source tag. (I know there is "est_width" but it has never been properly defined in the 20 years of use and was a bad idea from ancient times IMHO)

- the "source_area" doesn't need to be tagged, this is a property of the object itself

- "stem_count" doesn't need a new tag, "tree_count" is already in use. (maybe "

- "avg_spacing" is not needed, this can be calculated from the area and the number of trees

- for the size of crowns we already have 'diameter_crown'. It can be defined that it refers to the average size when used on areas with several trees.

Hi,
can anybody shop here 24/7 or do you need some kind of membership card?
node/9021268964

A key can't end with a colon - it should be either 'ref' or 'ref:XYZ'.

disc?

Hi,
this is the only occurrence of "payment:inpost" - but we have many "payment:inpost_mobile". Is this the same?

Perfect :)
styrofoam is actually listed in the table as "polystyrene_foam".
The wiki table is for sure not complete, but it's always a good starting point.

Another place to search is the list of tags that are actually in use, Taginfo:
https://taginfo.openstreetmap.org/keys/recycling#similar
As you can see there are about 200 recycling:* tags that are used more than say 10 times each.

If there's something that can't be found in any existing tag, you're always free to invent your own new one.

One more thing:
There's the tag
operator wikidata=Q135270647
The "wikidata" should be part of the key:
operator:wikidata Q135270647

Happy Mapping!

Hi,
something doesn't seem to be right here. There are 12 objects with a strange "ref:" key. Could you check that?

Hi & welcome to OSM!

You're using many recycling-related tags here that are not common.
Please have a look to the documented tags in the wiki and use only these - only well-defined tags can be understood by other mappers and can be shown on maps and in applications.

Here's the relevant table with common tags:
amenity=recycling#Recycling

Hi,
are the natural=water areas here really open water? In the images it looks rather like some wetlands. Could you check that?

Hi,
please check your edits. It's "building", not "buildiing".

Hi,
could you check your trees? The common tag for the trunk size is "circumference" in meters, not 'girth' in centimeters.

Hi,
please check your edits - you added many "buildng" instead of the correct "building".

Hi,
please check your edits - you added many "biulding" instead of the correct "building".

Hi, thank you for the check!
oneway:bus=no seems to be correct: It is a oneway road for everybody, but not for buses. It doesn't matter if they have their own lane, or (quite uncommon) they share a lane with opposite direction traffic.

Hi,
you added several tags here that shouldn't be in OSM, e.g.
"source:maxspeed:named_numbered" or
"source:maxspeed:app"

Could you check and fix this?

Hi,
could you check this building, both of the 'housenumber' tags it got don't seem right:

addr:housenumber = 170
addr:housenumber170 = 128
