Multiple ontologies in Neo4j

if we use multiple ontologies in Neo4j, should we include ontology name with every node?

I know people do that, but there could be some other (partitioning?) representation where Neo4j can have all the nodes within a single ontology node.

This assumes some kind of " partitioning " neo4j into several parts - ontologies.

Is that possible?
Any recommendations to optimize using multiple ontologies with Neo4j are highly appreciated.

Thank you for sharing!
