I confess that I am still getting to grips with 6.0.3 myself, so my apologies if I am way off track here, but I had assumed that with 6.0.3, you no longer required those neo4j-ogm libraries.
That's absolutely correct: Spring Data Neo4j 6 is not built upon Neo4j OGM (contrary to Spring Data Neo4j 5). Neo4j OGM annotations will not have any effect.
Thanks to both of you. Despite reading the docs, I did not consider your quote (" The current SDN does not need and does not support Neo4j-OGM.") as I should !
