Data flow control order generating apparatus and sensor managing apparatus

There is used a data flow control order generating apparatus that includes: a sensor side metadata acquisition unit acquiring sensor side metadata as information related to a sensor that outputs sensing data; an application side metadata acquisition unit acquiring application side metadata as information related to an application that provides a service by using the sensing data; a matching unit performing matching between the sensor side metadata and the application side metadata to extract the sensor capable of providing the sensing data that satisfies the request of the application; and an instruction unit transmitting a data flow control order that identifies the sensor extracted by the matching unit and the application to a sensor managing apparatus that manages the sensor.
