A tag on a node that belongs to a way but is unrelated to that wya.

I'm more concerned about existing data than I am about new data. How
do you handle nodes that you're not the source of?

What about an object which serves more than one abstraction/role? Eg a
pharmacy which is also a sandwich shop?
