IoTEntity

An IoTEntity is a software representation a physical entity, e.g. a house, a car or a door. IoTEntity corresponds to the IoT-A concept of Virtual Entity. An IoTEntity has properties: a house may have indoor temperature and energy consumption, a door may be locked or unlocked and opened or closed. The state of these properties at different points in time – typically generated by an IoTResource connected to a physical sensor - are represented by IoTStateObservations. State observations of an <a title="Basic IoTConcepts" href="http://www.iotworldservices.com/wiki/iotworldserviceswiki/iot-entity/">IoTEntity</a>, typically readings or measurements, can be acquired by two different methods: <ul> <li><a title="Events – Managing Subscriptions" href="http://www.iotworldservices.com/wiki/iotworldserviceswiki/events-managing-subscriptions/">Event subscriptions</a>, or a</li> <li><a title="The RESTful API" href="http://www.iotworldservices.com/wiki/iotworldserviceswiki/getting-and-setting-data-for-iotentities-using-events-and-rest/the-restful-api/">RESTful API</a>.</li> </ul> In both cases, a common content model for representations of IoTEntity objects is used. It is described in detail in: <ul> <li><a title="IoTEntity – Content Model" href="http://www.iotworldservices.com/wiki/iotworldserviceswiki/getting-and-setting-data-for-iotentities-using-events-and-rest/iotentity-content-model/">IoTEntity - Content Model</a></li> </ul>
