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.

semanticId: Optional[Reference] 🔗

(From HasSemantics)

Identifier of the semantic definition of the element. It is called semantic ID of the element or also main semantic ID of the element.

It is recommended to use a global reference.

supplementalSemanticIds: Optional[List[Reference]] 🔗

(From HasSemantics)

Identifier of a supplemental semantic definition of the element. It is called supplemental semantic ID of the element.

It is recommended to use a global reference.

qualifiers: Optional[List[Qualifier]] 🔗

(From Qualifiable)

Additional qualification of a qualifiable element.

Constraint AASd-021🔗

Every qualifiable can only have one qualifier with the same Qualifier.type.

embeddedDataSpecifications: Optional[List[EmbeddedDataSpecification]] 🔗

(From HasDataSpecification)

Embedded data specification.

orderRelevant: Optional[bool] 🔗

Defines whether order in list is relevant. If SubmodelElementList.orderRelevant = False then the list is representing a set or a bag.

Default: True

semanticIdListElement: Optional[Reference] 🔗

Semantic ID the submodel elements contained in the list match to.

It is recommended to use a global reference.

typeValueListElement: AasSubmodelElements 🔗

The submodel element type of the submodel elements contained in the list.

valueTypeListElement: Optional[DataTypeDefXsd] 🔗

The value type of the submodel element contained in the list.

value: Optional[List[SubmodelElement]] 🔗

Submodel element contained in the list.

The list is ordered.
