Abstract. In the Stream Reasoning (SR) and, in particular in RDF Stream Processing (RSP), working prototypes often came along with foundational research. RSP engines empirically proved SR feasibility and paved the road to applied and empirical research. Observing real systems highlights their heterogeneity and fostered new foundational investiga- tion. Indeed, RSP-QL is a model that unifies RSP approaches into a super semantics that can be used for correctness checking and optimization. In this paper we present a new RSP engine, Yasper, that implements RSP- QL semantics. We believe that Yasper will contribute to the adoption of RSP-QL and foster empirical investigations of the model.
