My work involves these semantic web technologies/ontologesi and I found the team is slowly but surely turning to more general graph-based tools such as Neo4j essentially abandoning triplestores. I wonder why the up take of triplestores are not massive? The tools and frameworks are excellent in my opinion but I find that not many tech people are interested in RDF/SPARQL/triplestores.
