Can arrows between nodes get labels similar to nodes in Neo4J. Nodes can be annotated by labels in Neo4J.
If the answer is NO, Is there any graphDB that arrows can accept labels as well as nodes and these labels are used in their corresponding query languages?
UPDATE: here a similar question is asked, and the answer was NO! anything changed since then?
回答1:
A relationship ("arrow") has a single "type", which is similar to a node label. However, a relationship can only have a single type.
