Hey Mueschel,
Could you join the discussion at https://community.openstreetmap.org/t/detention-centres-for-rejected-asylum-seekers/122453/16 instead of just changing the way I mapped these. I'd prefer you'd have contacted me about this. I just mapped this a few days ago, and I'm open to other ways of modelling the data. I understand just changing the data if the data model is according to a consensus and the mapper who made it has left or is not likely to answer messages. But neither is the case here.
