In this work we present an approach for Web-oriented event processing based on the combination of efficient event processing, expressive Semantic Web technologies and the management thereof. The approach is a distributed semantic system that serves as an Event Marketplace: heterogeneous events from the Web modelled in RDF are matched and integrated using a processing language we designed and describe in this work. The system consists of three main components: an event-driven service bus to connect event sources, a storage layer to maintain historic events and an event processing layer to combine, integrate, filter and derive events. Event-driven applications are implemented on this architecture by expressions in a language supporting hybrid queries mixing real-time (on pushed data) and historic (pull data) queries. A governance component enforces efficient access control on event streams and storage. The main advantages of the system are its Web-orientation by adhering to several open and extensible standards, its pattern language offering the combination of real-time and historical queries on events and its governance capabilities creating a multi-tenant system based on permissions. The system uses Web technologies such as Linked Data, RDF and SPARQL to model, organize, locate, process and control access to events.
