Abstract

In 2013 property paths were introduced with the release of SPARQL 1.1. These property paths allow for describing complex queries in a more concise and comprehensive way. The W3C introduced a formal specification of the semantics of property paths, to which implementations should adhere. Most commonly used RDF stores claim to support property paths. In order to give insight into how well current implementations of property paths work we have developed BeSEPPI, a benchmark for the semantic-based evaluation of property path implementations. BeSEPPI checks whether RDF stores follow the W3Cs semantics by testing the correctness and completeness of query result sets. The results of our benchmark show that only one out of 5 benchmarked RDF stores returns complete and correct result sets for all benchmark queries.
