4.2.288 Item_property_association

An Item_property_association is a mechanism to associate a property value with an object.

An Item_property_association is a type of Property_value_association.

The data associated with an Item_property_association are the following:

4.2.288.1 definitional

The definitional specifies whether the associated Property_value_representation object may be used to distinguish the described_element from others of the same kind. A value of 'true' indicates that the associated Property_value_representation distinguishes it from others.

The definitional is only meaningful, if the described_element is of type Catalogue_thread or of type Design_discipline_item_definition.

The definitional need not be specified for a particular Item_property_association.

4.2.288.2 described_element

The described_element specifies the object that is characterized by the Property_value.

See item_property_association to catalogue_thread, item_property_association to complex_product, item_property_association to design_constraint, item_property_association to design_discipline_item_definition, item_property_association to document_file, item_property_association to document_representation, item_property_association to feature_definition, item_property_association to general_feature, item_property_association to item_definition_instance_relationship, item_property_association to item_definition_relationship, item_property_association to item_instance, item_property_association to item_instance_relationship, item_property_association to item_shape, item_property_association to physical_instance, item_property_association to product_class, item_property_association to product_identification, item_property_association to product_structure_relationship, item_property_association to shape_element, item_property_association to shape_element_relationship, item_property_association to thread_feature, and item_property_association to transition_feature for the application assertions.

There shall be exactly one object that defines the described_element for an Item_property_association.
