[SOURCE: IEC 63278-1:2023, note added]
- class
-
description of a set of objects that share the same attributes, operations, methods, relationships, and semantics

- coded value
-
value that can be looked up in a dictionary and can be translated
- identifier (ID)
-
identity information that unambiguously distinguishes one entity from another one in a given domain
Note 1 to entry: there are specific identifiers, e.g. UUID Universal unique identifier, IEC 15418 (GS1).
[SOURCE: Glossary Industrie 4.0]
- minimum value
-
lower bound of a range of values in which the said value is meaningful
EXAMPLE 1: lowest value specified of a quantity, established for a specified set of operating conditions at which a component, device, equipment, or system can operate and perform according to specified requirements.
Note 1 to entry: additional information about the nature of the value can be obtained from the definition of the Property information object to which the value belongs.
[SOURCE: IEC 61360-1:2017]
- maximum value
-
upper bound of a range of values in which the said value is meaningful
EXAMPLE 1: highest value specified of a quantity, established for a specified set of operating conditions at which a component, device, equipment, or system can operate and perform according to specified requirements.
Note 1 to entry: additional information about the nature of the value can be obtained from the definition of the Property information object to which the value belongs.
[SOURCE: IEC 61360-1:2017]
- nominal value
-
value of a quantity used to designate or identify an item with its value, and not necessarily corresponding to the real value of the property
Note 1 to entry: additional information about the nature of the value can be obtained from the definition of the Property information object to which the value belongs.
[SOURCE: IEC 61360-1:2017]
- non-quantitative property
-
property that identifies or describes an object by means of codes, abbreviations, names, references or descriptions
EXAMPLE 1: typical information content of non-quantitative properties is items such as codes, abbreviations, names, references, or descriptions.
[SOURCE: IEC 61360-2:201 7– based on IEC 61360-2:2012, 3.28, modified – "data element type" is replaced by "property" in the term and definition.]
- property
-
defined characteristic suitable for the description and differentiation of products or components
Note 1 to entry: the concept of type and instance applies to properties.
Note 2 to entry: this definition applies to properties as described in IEC 61360/ ISO 13584-42.
Note 3 to entry: the property types are defined in dictionaries (like IEC component data dictionary or ECLASS), they do not have a value. The property type is also called data element type in some standards.
Note 4 to entry: the property instances have a value and are provided by the manufacturers. A property instance is also called property-value pair in certain standards.
Note 5 to entry: properties include nominal value, actual value, runtime variables, measurement values, etc.
Note 6 to entry: a property describes one characteristic of a given object.
Note 7 to entry: a property can have attributes such as code, version, and revision.
Note 8 to entry: the specification of a property can include predefined choices of values.

- quantitative property
-
property with a numerical value representing a physical quantity, a quantity of information or a count of objects
[SOURCE: IEC 61360-1:2017 – based on IEC 61360-2:2012, 3.40, modified – "data element type" is replaced by "property"]
- Submodel
-
representation of an aspect of an asset
[SOURCE: IEC 63278-1:2023]
- SubmodelElement
-
element of a Submodel
