What Is the Common Information Model?

The universal data model uses a self-describing, semantically active way to define and encapsulate the underlying data of sensors and their observations. More precisely, the universal data model is used to define the expression, nature, structure, and coding of sensors and their observation-related data. ^[1]

The universal data model uses a self-describing, semantically active way to define and encapsulate the underlying data of sensors and their observations. More precisely, the universal data model is used to define the expression, nature, structure, and coding of sensors and their observation-related data.

The main purpose of this model is to realize the interoperability of sensor networks, first at the grammatical level and then at the semantic level, so that the sensor and its observation data can be better understood by the machine and can be automatically processed in complex workflow In the case of smart sensor network nodes, it can also be easily shared.

Common data model defines the underlying data model for formal expression

The data types contained in the general data model are shown in the figure to the right;
