Event processing in RDF

Abstract. In this study we look at new requirements for event models based on concepts defined for complex event processing. A corresponding model for representing heterogeneous event objects in RDF is defined, building on pre-existing work and focusing on structural aspects, which have not been addressed before, such as composite event objects encap-sulating other event objects. SPARQL querying of event objects is also considered, to demonstrate how event objects based on the model can be recognized and processed in a straightforward way with SPARQL 1.1 Query-compliant tools.
