SPITFIRE Ontology
This ontology describes sensors, observations, and related concepts. It also describes events and their correlations. The final aim is to support a better description of sensor context.
This ontology is developed by DERI ( http://www.deri.ie ) for the SPITFIRE project ( http://spitfire-project.eu ) . It is based on the alignment among the W3C Semantic Sensor Networks Incubator Group (SSN-XG) ontology, the Dolce-DnS Ultralite ontology and the Event Model F ontology.
