Another graph design issue: id vs. label

["Larry Golding \(Comcast\)" <larrygolding@comcast.net>]

We’ve said that nodes and edges have “labels”, and that edge traversals have user-facing “messages”.

 

Is there a difference between {node,edge).id and {node,edge}.label? Ids are unique; can two nodes or two edges in the same graph have the same “label”? Do we need both?
