Hi @jseely,
You’d generally delete the edges. The node / entity doesn’t get deleted. Typically del operation would be part of our mutation segment, but support for it isn’t present in v0.3 yet.
mutation { set {<alice> <follows> <bob> . \n <alice> <name> "Alice" . \n <bob> <name> "Bob" . }}
mutation { del { <alice> <follows> <bob> . }}
We can set it for v0.4 release, if you think this would be useful.
