Gregory King: I had built a db in Neo4j Desktop with python scripts, and I thought, initially, that I could simply export it into csv files and import these files into AuraDB. It actually worked for nodes, but not for relationships, even though, on inspection, I did not detect field separators in any files.

I now realize that this approach does not work, and I am in the process of loading the same data using my python scripts. So far, so good.
