QuickGraph#8 revisited: LossLess graph copy between Neo4j DBs with RDF-star

Roughly a year and a half ago I posted QuickGraph#8 on how to copy all or part of your graph between neo4j DBs by serialising it as RDF with Neosemantics. It concluded on a sad note though, something along these lines: “Relationship properties will be lost in this process because RDF does not allow the representation of properties in edges”. Well, now we have RDF-star and the problem is solved. This is a brief update to that post where I explain how to overcome that hurdle.

Around the time of the release we did a live coding session going over some of the new features, one of which was RDF*. I thought I’d put a couple of examples in a quick graph similar to the ones in the video session to make it easier for people to find and give it a try. This is what you’re reading right now.
