Data Dictionary for Quantities Used in Cyber Physical Systems (AS6969B) This data dictionary provides definitions for quantities commonly used in the command and control of cyber physical systems. It defines mathematical and logical terms, quantities, measurement units, reference systems, measurands, and measurements. It also defines common quantity modalities. The dictionary is structured to be convenient to data modelers. It is also extendable so that users can create their own quantity domains.

Rationale

Content: This data dictionary provides definitions for quantities commonly used in the command and control of cyber physical systems. This data dictionary also provides a structure that may be extended to define quantities that are empirical to a specialist domain or an individual system. The National Science Foundation defines a cyber physical system as an engineered system that is built from, and depends upon, the seamless integration of computational algorithms and physical components. The term encompasses intelligent vehicles and devices, including robotic and autonomous systems. Cyber physical systems process and exchange state information across data links and networks about real-world entities. The semantics of this state information is typically defined by a data model and an associated data dictionary. Cyber physical systems and resources that share a common data model and data dictionary, therefore, exhibit semantic and conceptual interoperability and are more quickly integrated. In a data model, state information is expressed by the values of properties that are owned by real-world entities. Properties whose values have numerical magnitude are categorized as quantities. Properties whose values do not have numerical magnitude are categorized as nominal properties.
