Operation Operation is an abstract metaclass whose valid instances are binary operations used to compose condition and consequence expressions. These expressions can be used to construct dependencies between Form_Design_Element instances: e.g. List_Item and other Form_Design_Element instances. () Superclass Expression Attribute DataType Multiplicity Description operation Operation_Type 1..1 The operation invoked in an Expression with a maximum multiplicity of one. Reference Class Multiplicity Description Inverse Precedence The set of Operation instances containing_operation Expression 1..2 operation no associated by this Expression where the minimum multiplicity is maximum multiplicity is two. MDR_Mapping MDR_Mapping is a metaclass whose valid instances provide a means by which to map between instances of Form_Design_Elements. For example, to map a Question_Element a particular data element, either from MDR Registry, or some other data element specification, for the purpose of defining the semantics and input constraints of the Question_Element and its Responses.

Form_Design_Element_Association Form_Design_Element_Association is a metaclass whose valid instances map a Form_Design_Element to any identified item in a metadata registry, for example an MDR Registry.
