Hi all, SPARQL query language and the SPARQL protocol are implemented by a growing number of storage systems and are used within enterprise and open web settings. As SPARQL is taken up by the community there is a growing need for benchmarks to compare the performance of storage systems that expose SPARQL endpoints via the SPARQL protocol. We have been working over the last week on such a benchmark called the Berlin SPARQL Benchmark (BSBM). The benchmark is built around an e-commerce use case in which a set of products is offered by different vendors and consumers have posted reviews about products. The benchmark query mix illustrates the search and navigation pattern of a consumer looking for a product. We have also run the initial version of the benchmark against Sesame, Virtuoso, Jena SDB and against D2R Server, a relational database-to-RDF wrapper. The stores were benchmarked with datasets ranging from 50,000 triples to 100,000,000 triples. Our current benchmark spec as well as the results of our initial experiments are found at: http://www4.wiwiss.fu-berlin.de/bizer/BerlinSPARQLBenchmark/ In order to improve the Berlin SPARQL benchmark, it would be great to get feedback from the community on the benchmark specification. So if you think we have missed something essential or if you have ideas for further improvements, please let us know by replying to this mail or by contacting us directly. Also note that there is ongoing work on a second SPARQL benchmark: The SP2B SPARQL Performance Benchmark (http://dbis.informatik.uni-freiburg.de/index.php?project=SP2B). Compared with the BSBM benchmark, SP2B focuses more on testing different storage layouts and RDF data processing approaches while we try to be strictly use case driven. We are looking forward to your feedback :-) Cheers Chris and Andreas -- Chris Bizer Freie Universität Berlin Phone: +49 30 838 55509 Mail: chris@bizer.de Web: www.bizer.de
