Application module: Attribute classification | ISO/TS 10303-1246:2014-02(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 type for this application module. The MIM type and definition is specified below.
The attribute_classification_item type is an extensible list of alternate data types. Additional alternate data types are specified in select data types that extend the attribute_classification_item type.
NOTE This empty extensible select requires extension in a further module to ensure that entities that refer to it have at least one valid instantiation.

This subclause specifies the MIM entity for this module. The MIM entity and definition is specified below.
The value of the attribute being classified is the same as the id of the class.

Attribute definitions:
assigned_class: the class that defines the value of the attribute identified by attribute_name on the entity identified by items.
NOTE The attribute attribute_name is declared in the attribute_classification_assignment entity data type of which this entity data type is a subtype.
items: an instance of one of the types of attribute_classification_item. The instance shall have an attribute or an inherited attribute with name attribute_name.
