The Spatial Data on the Web Working Group has published a Working Draft of Semantic Sensor Network Ontology. The Semantic Sensor Network Ontology (commonly known as “SSN” or sometimes “SSNO”) is an OWL-2 DL ontology for describing sensors and the observations they make of the physical world. SSN is published in a modular architecture that supports the judicious use of “just enough” ontology for diverse applications, including satellite imagery, large scale scientific monitoring, industrial and household infrastructure, citizen observers, and Web of Things. SSN is described and examples of its use are given.
