4 Information requirements

This clause specifies the information requirements for the Alias identification application module. The information requirements are specified as the Application Reference Model (ARM) of this application module.

NOTE 1  A graphical representation of the information requirements is given in Annex C.

NOTE 2  The mapping specification is specified in 5.1. It shows how the information requirements are met by using common resources and constructs defined or imported in the MIM schema of this application module.

The following EXPRESS specification begins the Alias_identification_arm schema and identifies the necessary external references.

EXPRESS specification:

*)
SCHEMA Alias_identification_arm;
(*

4.1 Required AM ARM

The following EXPRESS interface statement specifies the elements imported from the ARM of another application module.

EXPRESS specification:

*)
USE FROM Identification_assignment_arm;    --  ISO/TS 10303-1021
(*

NOTE 1   The schemas referenced above are specified in the following part of ISO 10303:

Identification_assignment_arm ISO/TS 10303-1021

NOTE 2   See Annex C, Figures C.1and C.2 for a graphical representation of this schema.

4.2 ARM type definition

This subclause specifies the ARM type for this application module. The ARM type and definition is specified below.

4.2.1 alias_identification_item   EXPRESS-G

The alias_identification_item type is an extensible list of alternate data types. It provides a mechanism to refer to instances of the data types included in the types that extend the alias_identification_item type.

NOTE 1   This empty extensible select requires extension in a further module to ensure that all entities have at least one valid instantiation.

NOTE 2   The type alias_identification_item is not an extension of the type identification_item, defined in the application module Identification assignment, because the capability to get an alias may not be needed for every entity type to which the capability to get additional identifiers is provided. By nature, alias_identification_item characterizes a smaller set of entity types than identification_item.

EXPRESS specification:

*)
TYPE alias_identification_item = EXTENSIBLE GENERIC_ENTITY SELECT;
END_TYPE;
(*

4.3 ARM entity definition

This subclause specifies the ARM entity for this module. The ARM entity is an atomic element that embodies a unique application concept and contains attributes specifying the data elements of the entity. The ARM entity and definition is specified below.

4.3.1 Alias_identification   EXPRESS-GMapping table

An Alias_identification is a type of Identification_assignment that provides an alias identifier to product or activity data.

NOTE 1   The alias identifier is conveyed within the identifier attribute inherited from Identification_assignment.

NOTE 2   Information about the organizational scope in which the alias applies may be provided by a specialization of Organization_or_person_in_organization_assignment.

NOTE 3   Alias identification only applies to concepts that possesses an attribute that conveys an identifier.

EXPRESS specification:

*)
ENTITY Alias_identification
  SUBTYPE OF (Identification_assignment);
DERIVE
  SELF\Identification_assignment.role : STRING := 'alias';
WHERE
  WR1: SIZEOF (QUERY( item <* SELF\Identification_assignment.items | NOT ('ALIAS_IDENTIFICATION_ARM.ALIAS_IDENTIFICATION_ITEM' IN TYPEOF(item) ) )) = 0;
END_ENTITY;
(*

Attribute definitions:

role: the inherited attribute role. The value of role shall be 'alias';

Formal propositions:

WR1: the inherited items attribute shall not contain any element that is not aliasable.
