Hi omar_guc,
currently I'm investigating some rarely used building=* tags.
In the process I found way/1006213139, way/1006213140 and way/1006213141 which uses building=Felder, DMG Mori and Trumpf.
These tags are only used here.
Are Felder, DMG Mori and Trumpf the name of the buildings?
From my point of view building=industrial would fit better.
The tag landuse=industrial is used for areas and not for buildings.
See osm.wiki/Key%3Abuilding for details.
The now corrected verions would be:

building=industrial
building:levels=2
name=Trumpf

building=industrial
building:levels=2
name=Felder

and

building=industrial
building:levels=2
name=DMG Mori

If you have questions, please feel free to contact me.

Hi Andre,
dank für den Gruß.
Es macht Spass zu suchen und zu rätseln was manche Keys meinen, aber das Feedback ist fast immer sehr positiv.
Das motiviert mich weiterzumachen. Leider kommen ständig mehr Fehler hinzu als zu korrigieren sind.
Herzliche Grüße,

Hi Johnny Mapperseed,
I guess you meant building=house at way/753141705.

Hola Lvdens,
¿Se entiende lo siguiente en way/1078645554 en lugar de building=yse: building=yes?

Hello Lvdens,
At way/1078645554 , did you mean building=yes instead of building=yse?
With kind regards

Hi Hightlander1701,
thanks for the fast reply.
My focus was on the plural. You used semidetached_houses
and not semidetached_house. There are more then 900000 of them in OSM.
But thinking about it again you have a point here. There is no tag for the outline of two connected semidetached_houses.
For more then two houses there is building=terrace.
I had not thought about that then the house must be divided into 2 halves.
To be honest, I withdraw my proposal and am somewhat at a loss as to how to proceed correctly here.
Best Regards,
lyctkel

PS: The next 2 days I am very busy and will therefore answer later

Thank you!

Hi Seetroll,
gerade stolpere ich über way/101243114
Hier verwendest Du
building=Gewerblich .
Das ist etwas ungewöhnlich. Das Gebäude ist ja (nach meiner Erinnerung) ein Hotelgebäude. Demnach sollte
building=hotel
building:use=commercial
besser passen.
Herzliche Grüsse,

Hi fishosm,
zur Zeit untersuche ich selten genutzte Tags vom Typ building=*.
Dabei habe ich way/172459526 gefunden. Es verwendet building=security_lock.
Dieses Tag wird nur hier verwendet.
Mir erscheint seamark:type=gate zusammen mit seamark:gate:category=flood_barrage passender.
Details kann man hier finden
seamark:type=gate .
Herzliche Grüsse,
lyctkel
