Properties 🔗

extensions: Optional[List[Extension]] 🔗

(From HasExtensions)

An extension of the element.

category: Optional[NonEmptyString] 🔗

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[IdShort] 🔗

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[LangString]] 🔗

Display name. Can be provided in several languages.

If no display name is defined in the language requested by the application, then the display name is selected in the following order if available:

• the preferred name in the requested language of the concept description defining the semantics of the element
• If there is a default language list defined in the application, then the corresponding preferred name in the language is chosen according to this order.
• the English preferred name of the concept description defining the semantics of the element
• the short name of the concept description
• the Referable.idShort of the element

description: Optional[List[LangString]] 🔗

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.

checksum: Optional[NonEmptyString] 🔗

Checksum to be used to determine if an Referable (including its aggregated child elements) has changed.

The checksum is calculated by the user's tool environment. The checksum has no semantic meaning for an asset administration shell model and there is no requirement for asset administration shell tools to manage the checksum
