Virtual Entity & IoT Service Clause Samples

Virtual Entity & IoT Service. The Virtual Entity and IoT Service Functionality Groups include functions that relate to interactions on the Virtual Entity and IoT Service abstraction levels respectively. Figure 16 shows how the abstraction levels and how they are related. On the left side of Figure 16 the physical world is depicted. In the physical world there are a number of sensors and actuators that respectively capture and allow the change of certain aspects of the physical world. The Resources associated to the sensors and actuators are exposed as IoT Services on the IoT Service Level. Example interactions between applications and the IoT system on this abstraction level are “Give me the value of Sensor 456” or “Set Actuator 867 to On”. Applications can only interact with these services in a meaningful way, if they already know the semantics of the values, e.g. if Sensor 456 returns the value 20, the application has to be programmed or configured in such a way that it knows that this is the indoor temperature of the room of interest, e.g. Room 1.
