RE: [sarif] Another graph design issue: id vs. label

Interesting question. An id is used to uniquely identify something. A label is used to describe it in the viewer. I think we need both concepts. A descriptive label may be shortened in a way that renders it non-unique.

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?
