please follow the format from osm-wiki:

do not forget value="en:Name"

rules accoring to osm-wiki:
tourism=hotel

Please check now:
aeroway=aerodrome#Useful_Combination

It is also used in Wikipedia for most Airports, e.g.:
https://en.wikipedia.org/wiki/Berlin_Tegel_Airport

type is only for relation type, see:
type=*

so I used the Proposed_features to correct the wrong usage.
osm.wiki/Proposed_features/Aerodrome#type.3D.2A_still_has_some_.28historic.29_traction

OK

I agree.

ok fine. I only fixed the format thing.
wikipedia=Name, not wikipedia=en:Name,

PS: I also kept note=accomodation to be understood later. Perhaps a fixme would be needed?

I'm sotrry for this. But last time it was different: I used JOSM to cahnge >1000x e.g. type=Private to type=private and it was complained about that some other untouched tags were obviuosly wrong but overseen by the change.
But OSM has a general problem for beeing understood by tools (e.g. renderers). some call it "restaurant", some "restrant", some "Meyers Restaurant", some "Restaurant", or even "Beaitufull restaurant", etc.
We need to find a way to unify these different writings. Only special key=value-pairs have a real meaning.

you are right. first I tried to reduce different writings for similar things (e.g. typos, x-N , old-N disused:N, N:disused, N-closed). But perhaps it would be better to directly bring it into final state and skip the middle-step.

taginfo is a great help for it..
https://taginfo.openstreetmap.org/keys/amenity#values

hi SE, the problem is "accomodation" is an undefined value (see tourism=* ) and the old value was used world-wide only about 10 times.
To make the map more usable, I think it is a good idea to convert it to guest_house.
From psycological point of view: a Hotel is typically mapped as hotel, but Accom.. is used for smaller stuff. Before these sleeping-places were invisible to the renderer and other applications.
Can you agree to this?

the wikipedia link is broken

please follow these guidelines:
wikipedia=*

good. I only wanted to correct the bad link.

please fix empty key =-1 (Saturn)

no problem, I just want to understand.
So I will remove this key-value-pair.

why you added key="osm_id" to relation?
this is the only relation on planet having this.
https://taginfo.openstreetmap.org/keys/osm_id

what for is the key anyway? (since each obeject has its ID in osm)
