In October 2009, ERCIM News published a short article on Sensor-Web based prototype for CAFE (Clean Air For Europe) reporting:
Two European research projects, SANY (Sensors Anywhere) and the Austrian INSPIRE CAFE prototype are currently testing the usability of the Open Geospatial Consortium (OGC) Sensor Web Enablement (SWE) suite for CAFE (Clean Air For Europe) and INSPIRE (Infrastructure for Spatial Information in the European Community), by developing a prototype air quality reporting system in accordance with the CAFE directive. Unlike the Web Feature Service, which excels at geographic features, the SWE services and encodings help to model the world from a sensor-centric view, with each observed value being associated with a geographic and temporal position, as well as the unit of measurement, data quality value, and process description.
