please follow these guidelines:
osm.wiki/Key: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)

local tag only, no wiki, no information

comment wrong: in Algeria, fr.wikipedia

1. It gives the wrong impression, that someone measured with precision smaller than atom-size. Typical common assumption is: +- half last digit = accuracy.
2. Bytes are spend for noting.
3. Is there any benefit not to change it?

all nodes have only one tag (ele) with identical value. the used import tool had a format/rounding problem (a.b999999999999)

http://www.gcmap.com/airport/DRA
Elevation: 3314 ft (1010 m)

https://en.wikipedia.org/wiki/en:Desert Rock Airport
Elevation AMSL 1,010 ft / 308 m

https://en.wikipedia.org/wiki/Mercury,_Nevada
Elevation 3,789 ft (1,155 m)

==> ok you are right, and wikipedia is wrong.
I will go to ele=1010m again.

how to proceed here. could you fix this?
otherwise I need to understand what is wrong? Of course my comment was wrong, but something else?

why do you use ele=no for buildings in Leipzig?
ele=elevation=HöheÜberMeeresspiegel (unit = meter).
ele=no means nothing and should be avoided.
PS: height vs. ele should be considered.

Of course the content of these languages could be different, but this is not the point.
The connection between the languages is done by wikidata project.
For example: en:Berlin belongs to de:Berlin and fr:Berlin etc.
The content for articles (e.g in nation conflicts) could be the opposite, but wikidata will show all articles for same object in all languages. That was the master idea behind wikidata and its first project target. So anything that can be calculated from the data has not real need to be strored.

why you ignore:
osm.wiki/w/index.php?title=Key:wikipedia
cite: "In almost all cases, a single wikipedia tag as described above is sufficient."

wikidata.org was build to translate/link between different wikipedia language titles.
At least one linke should follow the international rule, I think.

I took a look here (and where thinking this is a global rule). In DE or US town is used from 10k to 99k.
Please change the rule here an tell the countries with town == city rule.

thanks, Alex

only relation["place"="city"]["population"~"[0-9]{7}"]({{bbox}}); // over europe timeout=444 is breaking with internal server error but only 23 cities >1mio are inside.
It should be doable, but is stille the limit (no timeout).
