Application module: Qualified measure | ISO/TS 10303-1782:2019(E) © ISO |
This clause specifies the EXPRESS schema derived from the mapping table. It uses elements from the common resources or from other application modules and defines the EXPRESS constructs that are specific to this part of ISO 10303.
This clause constitutes the Module Interpreted Module (MIM) of the application module.
This clause also specifies the modifications that apply to the constructs imported from the common resources.
The following restrictions apply to the use, in this schema, of constructs defined in common resources or in application modules:
Short names of entities defined in this schema are described in Annex A. Unambiguous identification of this schema is defined in Annex B.

This subclause specifies the MIM rule for this module. The MIM rule and definition is specified below.
It also specifies that any qualified_representation_item shall not contain more than one instance of uncertainty_qualifier with a specific measure_name.

Argument definitions:
global_uncertainty_assigned_context : the set of all instances of global_uncertainty_assigned_context.
qualified_representation_item : the set of all instances of qualified_representation_item.
uncertainty_assigned_representation : the set of all instances of uncertainty_assigned_representation.
Formal propositions:
WR1: Each instance of global_uncertainty_assigned_context shall not contain more than one instance of uncertainty_measure_with_unit with a specific name in its uncertainty set.
WR2: Each instance of uncertainty_assigned_representation shall not contain more than one instance of uncertainty_measure_with_unit with a specific name in its uncertainty set.
WR3: Each instance of qualified_representation_item shall not contain more than one instance of uncertainty_qualifier with a specific measure_name in its set of qualifiers.
