Properties 🔗

extensions: Optional[List[Extension]] 🔗: (From HasExtensions)

An extension of the element.
category: Optional[NameType] 🔗: (From Referable)

The category is a value that gives further meta information w.r.t. to the class of the element. It affects the expected existence of attributes and the applicability of constraints.

The category is not identical to the semantic definition (HasSemantics) of an element. The category e.g. could denote that the element is a measurement value whereas the semantic definition of the element would denote that it is the measured temperature.
idShort: Optional[IdShortType] 🔗: (From Referable)

In case of identifiables this attribute is a short name of the element. In case of referable this ID is an identifying string of the element within its name space.

In case the element is a property and the property has a semantic definition (HasSemantics.semanticId) conformant to IEC61360 the Referable.idShort is typically identical to the short name in English.
displayName: Optional[List[LangStringNameType]] 🔗: (From Referable)

Display name. Can be provided in several languages.
description: Optional[List[LangStringTextType]] 🔗: (From Referable)

Description or comments on the element.

The description can be provided in several languages.

If no description is defined, then the definition of the concept description that defines the semantics of the element is used.

Additional information can be provided, e.g., if the element is qualified and which qualifier types can be expected in which context or which additional data specification templates are provided.
administration: Optional[AdministrativeInformation] 🔗: (From Identifiable)

Administrative information of an identifiable element.

Some of the administrative information like the version number might need to be part of the identification.
id: Identifier 🔗: (From Identifiable)

The globally unique identification of the element.
embeddedDataSpecifications: Optional[List[EmbeddedDataSpecification]] 🔗: (From HasDataSpecification)

Embedded data specification.
derivedFrom: Optional[Reference] 🔗: The reference to the AAS the AAS was derived from.
assetInformation: AssetInformation 🔗: Meta-information about the asset the AAS is representing.
submodels: Optional[List[Reference]] 🔗: References to submodels of the AAS.

A submodel is a description of an aspect of the asset the AAS is representing.

The asset of an AAS is typically described by one or more submodels.

Temporarily no submodel might be assigned to the AAS.
