    This example shows how to run SPARQL queries over Spark using a SPARQL-to-SQL rewriter under the hood.

    This example shows how to run SPARQL queries over Spark using a SPARQL-to-SQL rewriter under the hood. The RDF data can be provided either as triples file or even as a pre-partitioned dataset maintained in tables of a Spark database and a corresponding R2RML mapping file.

    Two different modes for demonstrator purposes can be used: - run a single query - start a SPARQL endpoint with a Web UI as optional interface
