Sensor data is stored and published using OGC's (Open Geospatial Consortiums) observation & measurement specifications as underlying data model. With the advent of volunteered geographic information and the semantic sensor Web, work on an ontological, i.e. conceptual, model gains importance within the sensor Web enablement community. In contrast to a data model, an ontological approach abstracts from implementation details by focusing on modeling the real world from the perspective of a particular domain or application and hence, restricts the interpretation of the used terminology towards their intended meaning.
