ISO 10303-214:2010(E)
A Classification_association associates a General_classification with one or more objects.
The data associated with a Classification_association are the following:
The associated_classification specifies the General_classification object that provides classification information.
See classification_association to general_classification for the application assertion.
The classified_element specifies the objects that are classified.
See classification_association to activity, classification_association to activity_method, classification_association to approval_status, classification_association to catalogue_thread, classification_association to complex_product, classification_association to contract, classification_association to design_constraint, classification_association to design_discipline_item_definition, classification_association to document, classification_association to document_file, classification_association to document_representation, classification_association to document_version, classification_association to effectivity, classification_association to feature_definition, classification_association to general_feature, classification_association to item, classification_association to item_instance, classification_association to item_version, classification_association to material, classification_association to process_operation_definition, classification_association to process_operation_occurrence, classification_association to process_plan, classification_association to product_class, classification_association to product_identification, classification_association to project, classification_association to property, classification_association to property_value_association, classification_association to security_level, classification_association to shape_element, classification_association to simple_property_association, classification_association to specification, classification_association to specification_category, classification_association to thread_feature, classification_association to transition_feature, classification_association to work_order, and classification_association to work_request for the application assertions.
There shall be at least one object that defines the classified_element for a Classification_association.
The definitional specifies whether a General_classification serves as definition. A value of 'true' indicates that the General_classification is definitional. The 'associated_classification' does not take precedence over the descriptions of the 'classified_element' made using Property_value or Geometric_model objects.
The attribute definitional shall only be used, if the classified_element is of one of the types Material, Item, Item_version, Design_discipline_item_definition, or Catalogue_thread.
The definitional need not be specified for a particular Classification_association.
The role specifies the relationship between the General_classification and the associated object.
Where applicable the following values shall be used:
The role need not be specified for a particular Classification_association.
