ISO 10303-214:2010(E)
An Alias_identification is a mechanism to associate an object with an additional identifier that is used to identify the object of interest in a different context, either in another Organization, or in some other context. The scope of the Alias_identification shall be specified either by the attribute 'alias_scope' or by the attribute 'description'.
EXAMPLE A document (e.g., a book) may have a unique document id (ISBN) and an Alias_identification as inventory number in the context of the inventory of a company.
The data associated with an Alias_identification are the following:
The alias_id specifies the identifier used in the context specified by the alias_scope, or by the description.
The alias_scope specifies the Organization in which the Alias_identification is valid.
See alias_identification to organization for the application assertion.
The alias_scope need not be specified for a particular Alias_identification.
The alias_version_id specifies the version of the object as known in the context of the Alias_identification.
NOTE An alias_version_id may be applied even if the object of interest does not have versions.
The alias_version_id need not be specified for a particular Alias_identification.
The description specifies the type of the Alias_identification.
EXAMPLE The description may be, e.g., 'inventory number'.
See alias_identification to multi_language_string for the application assertion.
The description need not be specified for a particular Alias_identification.
If present, there shall be exactly one object that defines the description for an Alias_identification.
The is_applied_to specifies the object that has an Alias_identification.
NOTE If applied to an Approval_status, a Document_type_property, or a Security_level, it is not the id but the name attribute having an alias.
See alias_identification to activity, alias_identification to approval_status, alias_identification to classification_attribute, alias_identification to classification_system, alias_identification to complex_product, alias_identification to design_discipline_item_definition, alias_identification to document, alias_identification to document_representation, alias_identification to document_type_property, alias_identification to document_version, alias_identification to general_classification, alias_identification to geometric_model, alias_identification to item, alias_identification to item_instance, alias_identification to item_version, alias_identification to organization, alias_identification to physical_instance, alias_identification to product_class, alias_identification to project, alias_identification to property, alias_identification to security_level, alias_identification to specification, alias_identification to specification_category, alias_identification to styled_model, alias_identification to work_order and alias_identification to work_request for the application assertions.
There shall be exactly one object that the Alias_identification is_applied_to.
