Hi. Could you explain your rationale for these edits to college staircases?
Personally, I am not sure that the new solution is an improvement.
They are sui generis buildings. They don't have addresses, so I question the use of the 'addr' tag.
I think the previous use of 'name', while not perfect, is more appropriate, and certainly clearer for the user, especially because the staircases are mapped as distinct buildings. (If the whole building was a single area, with individual entrances mapped as nodes, I could see the unit approach working more, but that's a bigger change, and again, it would lose information more than add).
