Location entity locates the Thing or the Things it associated with. A Thing’s Location entity is defined as the last known location of the Thing. A Thing’s Location may be identical to the Thing’s Observations’ FeatureOfInterest. In the context of the IoT, the principle location of interest is usually associated with the location of the Thing, especially for in-situ sensing applications. For example, the location of interest of a wifi-connected thermostat should be the building or the room in which the smart thermostat is located. And the FeatureOfInterest of the Observations made by the thermostat (e.g., room temperature readings) should also be the building or the room. In this case, the content of the smart thermostat’s location should be the same as the content of the temperature readings’ feature of interest.

}

Thing in SensorThings represents a physical object in the real world. A Thing is a good starting point in which to start creating the SensorThings model structure. A Thing has a Location and one or more Datastreams to collect Observations. A minimal Thing can be created without a Location and Datastream and there are options to create a Things with a nested linked Location and Datastream.
