Hello Tjuro,
thank you for your message and the proposal to use more specific tags for the area.
I am not shure if I got you right:
Do you want me to a) replace "landuse=village_green" by another tag or b) simply add other tags?

For a) From my point of view landuse=village_green is in general the correct tag as the area is public, and open for the local community. It is common to have small areas like this in rural areas to serve as meeting point for the local community (in this case the inhabitants of a small farming community / village named "Stapelfeld". The name for places in some regions of Germany is "Anger". The German word "Anger" is translated to the English "village green".
If b) I could imagine to add the tag "landcover=greenery" as the areas consists mainly of maintained grass with a small shelter and a place for bbq.
Looking forward for your answer
Greeting, jmsbert
