[SOURCE: IEC 63278-1:2023, note added] class description of a set of objects that share the same attributes, operations, methods, relationships, and semantics [SOURCE: IEC TR 62390:2005-01, 3.1.4] coded value value that can be looked up in a dictionary and can be translated [SOURCE: ECLASS [1]] 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. [SOURCE: according to ISO/IEC Guide 77-2] as well as [SOURCE: according to Glossary Industrie 4.0] 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 [SOURCE: IEC 63278-1:2023] Abbreviations Used in Document Abbreviation Description AAS Asset Administration Shell AASX Package file format for the Asset Administration Shell API Application Programming Interface BLOB Binary Large Object CDD Common Data Dictionary GUID Globally unique identifier ID Identifier IDTA Industrial Digital Twin Association IEC International Electrotechnical Commission IRDI International Registration Data Identifier IRI Internationalized Resource Identifier ISO International Organization for Standardization JSON JavaScript Object Notation MIME Multipurpose Internet Mail Extensions PDF Portable Document Format RDF Resource Description Framework RFC Request for Comment UML Unified Modelling Language URI Uniform Resource Identifier URL Uniform Resource Locator URN Uniform Resource Name UTC Universal Time Coordinated VDE Verband der Elektrotechnik, Elektronik und Informationstechnik e.V.
