ISO 10303-214:2010(E)
A Classification_attribute is a characteristic used to classify an object associated with the corresponding General_classification. The definition attribute of each 'allowed_value' shall refer to the property identified within 'attribute_definition'.
The data associated with a Classification_attribute are the following:
The allowed_value specifies the set of Property_value_representation objects that represent characteristic values of the Classification_attribute.
See classification_attribute to property_value_representation for the application assertion.
The associated_classification specifies the General_classification the Classification_attribute is a characteristic of.
See classification_attribute to general_classification for the application assertion.
The attribute_definition specifies the Property that characterizes the allowed values.
NOTE The specification of compound characteristics can be realized by using Property_relationship with 'relation_type 'peer' or 'decomposition'.
See classification_attribute to property for the application assertion.
The description specifies additional information about the Classification_attribute.
See classification_attribute to multi_language_string for the application assertion.
The description need not be specified for a particular Classification_attribute.
If present, there shall be exactly one object that defines the description for a Classification_attribute.
The id specifies the identifier of the Classification_attribute that shall be unique within the scope of the associated General_classification.
EXAMPLE 'a' or 'b' for length or width attributes or 'r' for radius attributes are examples for identifiers of Classification_attribute objects. The meaning of such ids is usually specified in external sources.
The name specifies the word or group of words by which the Classification_attribute is referred to.
EXAMPLE 'length', 'width', or 'radius' are examples for the name of a Classification_attribute.
See classification_attribute to multi_language_string for the application assertion.
The name need not be specified for a particular Classification_attribute.
If present, there shall be exactly one object that defines the name for a Classification_attribute.
