Standard provides a common data encoding that is used throughout the OGC Sensor Web Enablement (SWE) standards suite
This model is used for describing static data (files) as well as dynamically generated datasets (on-the-fly processing), data subsets, process and web service inputs and outputs and real time streaming data. All categories of sensor observations are in scope ranging from simple in-situ temperature data to satellite imagery and full motion video streamed out of an aircraft.
The SWE Common language is an XML implementation of this model and is used by other existing OGC® Sensor Web Enablement standards such as Sensor Model Language (SensorML), Sensor Observation Service (SOS), Sensor Alert Service (SAS) and Sensor Planning Service (SPS).
