Following is a proposal on how to to handle a group of dynamic parameters.   Per the diagram, this would apply to any design entity (ServiceDesc, Vnfd, Pnfd, etc.) along with the corresponding runtime entity.


Updates included in this version:

  1. Changed ParameterSpecValue value, valueFrom, and valueTo multiplicity from 1 to 0..1
  2. Changed Parameter unitOfMeasure multiplicity from 1 to 0..1
  3. Added root diagram for context regarding DesignEntity and OperationalEntity

1.2.1.1.1        Parameter class

Qualified Name: Common::Root::RootObjectClasses::Parameter

Description:

Some parameter that is part of a ParameterGroup.   If parameter can only hold certain values, those values are specified via ParameterSpecValue (design time).   The actual value is specified via ParameterValue (runtime).

Applied Stereotypes:

  • Experimental
  • OpenModelClass
