Implementation in Proteus Schema

All data attributes with type NullableLength (the base type of Length) are implemented as DEXPI generic attributes for physical quantities.

Example

The instance length1 represents a Length of 20.0 cm.

Implementation in Proteus Schema

<GenericAttribute
  Format="double"
  Value="20.0"
  Units="Centimetre"
  UnitsURI="http://data.posccaesar.org/rdl/RDS1318004" ...>

Note that the <GenericAttribute> element must have a Name and an AttributeURI attribute. They depend on the data type attribute of the DEXPI class that owns the instance length1. For a complete example, see the attribute Diameter of the DEXPI class AgitatorRotor.
