Dear Kamal, Thank you for the answer.
Pardon my incompetence if I somehow misunderstood, but what I see in your example is Cypher queries, which isn't problematic (I could solve my needs by using CASE, but FOREACH also seems working, thanks). The problem I'm having is rather whereas this can be done with neo4j-import (or neo4j-admin). Because, without that, neo4j-import would be limited to very simple DBs as we can't reproduce Cypher scripts with it. If I'm mistaken and it's possible to be done, any pointer on how to would be awesome.
