The W3C Semantic Sensor Network Incubator group (the SSN-XG), as one of its activities, produced an OWL 2 ontology to describe sensors and observations the SSN ontology, available at The SSN ontology can describe the capabilities of sensors, the measurement processes used and the resultant observations, and can be aligned with other ontologies, e.g., that describe observed phenomena. This article describes the development of the SSN ontology, the ontology and its alignment to the DOLCE-UltraLite foundational ontology, and the uptake in recent research projects and applications.
