Implementation in Proteus Schema

Implementation is subclass-specific.

Example

As TechnicalItem is abstract, we consider ActuatingElectricalFunction as an arbitrary concrete subclass.

Implementation in Proteus Schema

<ActuatingElectricalFunction
    ID="actuatingElectricalFunction1"
    ComponentClass="ActuatingElectricalFunction"
    ComponentClassURI="http://sandbox.dexpi.org/rdl/ActuatingElectricalFunction" ...>
  ...
</ActuatingElectricalFunction>

ParentStructure

Attribute (reference)

A superordinate structure of which the TechnicalItem is a part.

Multiplicity: 0..1

Type: TechnicalItemParentStructure

Opposite multiplicity: 0..*

Implementation in Proteus Schema

The attribute is implemented using Proteus <Association> elements.

Association type for the attribute ower: "is a part of"

Opposite association type: "is a collection including"
