Neo4j is not an RDF database in its raw form. Its data model is a bit more complicated than RDF and as such, is not amenable to SPARQL which assumes only an edge-labeled graph. However, with that said, the pattern matching functionality of Cypher is somewhat analogous to SPARQL so you might find solace in that. Moreover, you can also use Gremlin for pattern matching, though it doesn't have the same look-and-feel as SPARQL (see https://github.com/tinkerpop/gremlin/wiki/SPARQL-vs.-Gremlin ). Next. If you actually have used GraphSail (via Blueprints) to model your data as an RDF graph in Neo4j, then you can access it via Sesame SPARQL engine --- however, as it stands, not via the Neo4j REST server without rolling your own extension. If you are so inclined, you can either use Rexster (http://rexster.tinkerpop.com) and its SPARQL "kibble" or steal the code in Rexster's SPARQL kibble and make it work for Neo4j Server (shouldn't be more than an a few hours work). see http://rexster-kibbles.tinkerpop.com/ https://github.com/tinkerpop/rexster-kibbles/tree/master/sparql-kibble Hope that is clear, Marko. http://markorodriguez.com _______________________________________________ Neo4j mailing list [email protected] https://lists.neo4j.org/mailman/listinfo/user
