Hello Spaghetti Monster,

I think Dillen GJ is referring to having the building= tag reflect the original purpose of the building.

Adding poi tags like amenity=prison to buildings is not part of that.

In NL we do more strictly enforce separation between poi's and buildings. amenity=* should never be on a building even if it is still in use.

I have modified the building.

Greetings,

Tjuro
