and edit the tagging to preserve the ID and history, but there are cases
where this can't happen. For example I know a map that closed and got
removed from the map (it looked like it would be converted to houses rather
than re opened), but it reopened and I had to add it as a new node.

If you want a QR code, I understand these are usually(always?) just internet
URLs converted into a 2D barcode. For this you can use
