Modeling and querying sensor services using ontologies

Abstract

We propose in this paper a service description meta-model for describing services from a functional and non-functional perspectives. The model is inspired from the frame based modeling technique and is serialized in RDF (Resource Description Framework) using Linked Data principles. We apply this model for describing sensor services: modeling sensors and their readings enriched with non-functional properties. We also define a complete architecture for managing sensor data: collection, conversion, enrichment and storage. We tested our prototype using live streams of sensors readings. The paper also reports on the required time and storage size during the management and querying of sensor data.
