The Query is in Cypher, my preference is for this property to refer to
Cypher rather than Neo4J. See my other comments about making this processor
more generic to support more openCypher platforms.
Also, would Cypher's syntax cause issues when evaluating Expression
Language? It doesn't look like you're using parameters so I wouldn't expect
something like an "UNWIND $myList" or anything, but just in case it might be a
good idea to mention any caveats, limitations, etc. in the description of this
property.
