Processing of RDF Stream Data

We are witnessing a paradigm shift, where real-time, time-dependent data is becoming ubiquitous. As Linked Data facilitates the data integration process among heterogenous data sources, RDF Stream Data has the same goal with respect to data streams. It bridges the gap between stream and more static data sources. To support the processing on RDF stream data, there is a need on investigating how to extend RDF to model and represent stream data. Then, from the RDF-based data representation, the query model processing models need to be defined to build the stream processing engine that is tailored for streaming data. This chapter provides an overview on how such requirements are addressed in the current state-of-the-art of RDF Stream Data processing.
