Inconsistent place on relation and label_node

[Noki]

Hi!

We're currently play around with openstreetmap data and found quite some inconsistencies between administrative areas and the corresponding label nodes. The inconsistencies make it really hard to automatically build a trustworthy hierachie.

We found 1024 relations where the place of the relation and the area differs.

In my opinion areas and corresponding label nodes should always have the same place and whenever there are multiple administrative levels there should be a relation for each one of them, even if they cover exactly the same area (correct my when I'm wrong).

From what I can see most of the time the correct place is at the area.

I tried to write a challenge for it but I could not get the data selection working with the Overpass API.

Here is what I was trying to do:

RELATION MUST HAVE boundary=administrative AND place AND has(lable_node)
CHECK: relation->place <> label_node->place

Maybe someone could help with this one. Here is a list of affected relations: https://docs.google.com/spreadsheets/d/1yu1-3F8VYF8hA4ZuE_P_bIyuFpz_XZAbWRjlrDd8sdU/edit#gid=1380947132
