Since a Structure is a type of Asset, the Pole inherits all of the attributes from both Structure and Asset * For more information

20 The CIM is expressed in UML Notation Class Name usually describes things in the real world Class Attributes describe significant aspects about the thing This Specialization indicates that a Pole is a type of Structure. Since a Structure is a type of Asset, the Pole inherits all of the attributes from both Structure and Asset * For more information on UML notation (a standard), refer to Martin Fowler s book UML Distilled, Addison-Wesley Associations connect classes and are assigned a role that describes the relationship 20
