Benchmark assesses SPARQL-star support and performance in RDF-star triplestores, highlighting challenges and opportunities.
RDF-star has rapidly gained popularity as a way to annotate RDF statements while avoiding the disadvantages of reification. Hence, a number of triplestores supporting this new standard have become available. Yet, it is difficult to assess the performance of these systems and to which degree they support RDF-star and the corresponding SPARQL-star query language. Hence, in this paper, we propose StarBench, a benchmark for testing SPARQL-star support and runtime performance. We ran StarBench on a number of state-of-the-art triplestores with RDF-star and SPARQL-star support and share our findings. Based on these findings, we highlight existing challenges and research opportunities.
