SYSML11 — 08 Blocks, Unit, ValueType

  • Key: SYSML11-84
  • Legacy Issue Number: 12128

  • Summary:

    Suggest Unit and ValueType both extend abstract DimensionedType, and inherit a 'dimension' attribute This strategy provides a compact and elegant metamodel for units and values, and expresses well the underlying physical and mathematical principles of a dimensioned quantity represented by a value subject to chosen units. Value properties can then be sensibly typed by either a Unit or a ValueType. In the case where a ValueType has a Unit, the constraint still applies that the dimension of the ValueType must be the same as the dimension of the Unit. See also analysis image and commentary at:
