Hi,
"ad_libitum" is not a common tag. Do you mean "all_you_can_eat"?

Hi,
there are some ways with a strange tag here, could you check that?

Hi,
I didn't add these names, they are there since 3 years. I just fixed the mistake in the keys with a ':' at the end.

What is easier or faster depends a lot on the specific use case.
Separate tags makes parsing the value slightly quicker (you save just a simple split operation of a string), but on the other hand it makes finding the tags a lot more expensive: Your database request doesn't ask for a simple key, but you need a wildcard search for numbers as subkeys.

In general, I prefer the list in a single tag - any software has to be able to cope with this syntax, supporting yet another tag is a non-issue.

Hi,
please check these edits. The common tag is "motorcycle:sales", not "motorcycle:sale".

Hallo,
ich habe hier ein paar maxspeed tags korrigiert. Die richtige Reihenfolge im Key ist "maxspeed:hgv:forward". Erst das Fahrzeug, dann die Richtung.

Hi,
it's not necessary to add almost 30 "frequency:78" tags to a single object. You can just combine them in a single tag, separated with a semicolon.

Hi,
here are some payment tags on a highway, but there is no tag about a toll or similar. Could you check that?
way/565349328

Hi,
in total 18 of the tags you added are not used in any other place - that makes it unlikely that any tool will understand them. I'd suggest to check some other similar airports to see how they are tagged.

Especially suffixes like "primary" or "ft" are not generally used. Information like the runway length should be added to the runway itself.

Hi,
danke für den Hinweis. Diesen Key hatte ich nicht gesehen, weil er schon seit einem Import 2012 existiert (mit yes/no).

Koordinaten von Objekten in Tags sind unnötig, da sich der Knoten ja bereits an der richtigen Stelle befindet. Nur wenn Koordinaten explizit auf dem Objekt vermerkt sind (Vermessungspunkte etc.) kann ein Tag Sinn machen.

Ich wäre dafür diese Tags zu entfernen.

Could you check this way, it got a strange 'ogau' tag:
way/243761489#map=18/49.543112/25.611674

Hi,
"routePoint" is not used in other places. Is this number a kind of gtfs reference or similar?

JOSM doesn't highlight unknown tags - unless they contain other errors like spaces like in this case. I can't simply change them without knowing what a "centre de sante" is in the local context.

There are very few tools that mark random tags as error / warning, but many tools that highlight 'fixme'. The edit made the problem much more visible to most mappers.

Hi,
something went wrong here. Most of this data are duplicates of existing features.
This happens if you load a geojson or similar file into JOSM and then try to upload it. You have to load data directly from the API or Overpass - every other way will lead to duplicates and not to editing the already existing objects.

I reverted these changes.

Hi,
what exactly are these survey_points?
node/12870964132

A monitoring station for cell phone signal strength?

Hi,
would you please point us to the discussion and documentation of this massive world-wide retagging of food amenities?
New tags are not introduced by creating a Wiki page and immediately retagging objects all across the world.

A new top-level tag for one special kind of food is a weird choice. There are established tagging schemes that should be followed.

Hi,
die Mühe, alle Tags mit einem "abandoned:" zu versehen brauchst du dir nicht machen.

abandoned:amenity=telephone
und vielleicht noch ein paar Tags welche das Aussehen beschreiben sind völlig ausreichend - alles andere kann weg, da es ja eindeutig keine Chance mehr gibt, dass das jemals noch eine Rolle spielen wird.

Hi,
'recycling:energy_waste' is not in use in other places - what does it mean?

Hi,
could you check this relation, it got a strange tag:

charge:condition = 1.50 GEL
