Big fan of Jena. The command line tools alone for running SPARQL queries and converting between formats is great. Can anyone compare and contrast Jena in a Java project and/or operation against flat files with Neo4J or other graph systems?
Jena is an RDF triple store whereas Neo4J, Memgraph, or JanusGraph, for example, are property label graphs. Two different data models with distinct use-cases. I would compare Jena to other RDF engines like Stardog or Anzo graph.
From a java project perspective, it doesn't really matter which one you choose as they all expose JDBC.
