Fecha de publicación: 15/01/2020 Fuente: Wipo "Sensorization" Provided are a sensor metadata generation device, a sensor metadata generation system, a sensor metadata generation method, and a sensor metadata generation program capable of generating metadata of the same format for sensors that output equivalent sensing data. A sensor metadata generation device 10 includes: a class storage unit 15 configured to store a sensor container class that includes, as components, one or a plurality of sensor classes each including definitions of attributes of one or a plurality of sensors, and a sensor composition class including a composition condition for compositing the one or a plurality of sensors as a single sensor entity, with a first interface that includes a declaration of a metadata acquisition method for acquiring metadata; an object generation unit 16 configured, based on the sensor container class, to generate a sensor container object in which the configuration of the single sensor entity is defined; and a metadata acquisition unit 17 configured to use the metadata acquisition method by the sensor container object to acquire metadata of the single sensor entity.
