Data flow control order generating apparatus and sensor managing apparatus

A data flow control order generating apparatus comprising:

• a sensing data metadata acquisition unit acquiring metadata of sensing data as information related to the sensing data obtained by a sensor and stored in a database on a network;
• 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 metadata of the sensing data and the application side metadata to extract the sensing data that satisfies a request of the application;
• and
• an instruction unit transmitting a data flow control order that identifies the sensing data extracted by the matching unit and the application to the database on the network.

A sensor managing apparatus that manages a sensor by using sensor side metadata as information related to the sensor that outputs sensing data,

• the apparatus comprising:
• an order reception unit receiving a data flow control order that identifies the sensor extracted as a sensor that satisfies a request of an application by matching between application side metadata as information related to the application that provides a service by using the sensing data and the sensor side metadata, and also identifies the application;
• and
• a transmission unit transmitting the sensing data from the extracted sensor to the application on a basis of a predetermined packet system via a network.

A data flow control order generating program causing an information processing apparatus to execute:

• a sensor side metadata acquisition step of acquiring sensor side metadata as information related to a sensor that outputs sensing data;
