These queries are adapted from CityBench.

CityBench is a java-based benchmarking toolset for RDF Stream Processing (RSP) engines. The data and streams used in CityBench are from the CityPulse project that collected a set of smart city data from Aarhus, Denmark in 2014 and 2015 which includes parking, events, pollution, traffic and weather data from sensors.

The S2S engine, formerly called sparql2stream, uses data model mappings in the S2SML language to translate from a RSP to an EPL query that can be executed on Esper, a Complex Event Proceesing (CEP) engine.
