RSP4J: An API for RDF Stream Processing

The RDF Stream Processing (RSP) community has proposed several models and languages for continuously querying reasoning over streams the last decade. They each have their semantics, making them hard to compare. variety of approaches fostered both empirical theoretical research led design RSPQL, i.e., a unifying model RSP. However, an RSP API development under RSPQL semantics was still missing. would benefit from because it can foster comparable reproducible by providing programming abstractions based on semantics. Moreover, encourage further in-use research. Finally, stimulate practical activities such as tutorials, lectures, challenges, e.g., during Reasoning Workshop.In this paper, we present RSP4J, flexible engines applications RSP4J offers all necessary required fast-prototyping Users configure reproduce engine behaviors in software environment. To promote systematic comparative research, is open-source, provides canonical citation, permanent web identifiers, comprehensive user guide developers.
