SPARQL Query Benchmarker Wiki A simple tool for testing SPARQL system performance and reliability Introduction SPARQL Query Benchmarker started life purely as a SPARQL over HTTP benchmarking tool. Over time it has evolved into a general purpose API that while designed primarily for testing remote SPARQL servers (including queries, updates and GSP requests) can in principal be extended to test much
If you plan to run the benchmark to test your own implementation, you can find both the data generator and benchmark queries at our download section. Abstract Recently, the SPARQL query language for RDF has reached the W3C recommendation status. Addressing the needs of this new standard, the database community is currently exploring efficient storage techniques for RDF data and evaluation strategi
