4 Information requirements

This clause specifies the information requirements for the External library 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.

This clause defines the information requirements to which implementations shall conform using the EXPRESS language as defined in ISO 10303-11. The following begins the External_library_arm schema and identifies the necessary external references.

EXPRESS specification:

*)
SCHEMA External_library_arm;
(*

4.1 Required AM ARMs

The following EXPRESS interface statements specify the elements imported from the ARMs of other application modules.

EXPRESS specification:

*)
USE FROM External_source_arm;    --  ISO/TS 10303-1331

USE FROM Plib_class_reference_arm;    --  ISO/TS 10303-1291
(*

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

External_source_arm ISO/TS 10303-1331
Plib_class_reference_arm ISO/TS 10303-1291

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 el_external_identification_item   EXPRESS-G

The el_external_identification_item type is an extension of the external_identification_item type. It adds the data type User_defined_library_or_dictionary to the list of alternate data types.

NOTE  The list of entity data types may be extended in application modules that use the constructs of this module.

EXPRESS specification:

*)
TYPE el_external_identification_item = EXTENSIBLE GENERIC_ENTITY SELECT BASED_ON external_identification_item WITH
   (User_defined_library_or_dictionary);
END_TYPE;
(*

4.3 ARM entity definitions

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

4.3.1 Iso15926_4_rdl   EXPRESS-GMapping table

An Iso15926_4_rdl is a type of Known_source.

EXPRESS specification:

*)
ENTITY Iso15926_4_rdl
  SUBTYPE OF (Known_source);
END_ENTITY;
(*

4.3.2 Known_source   EXPRESS-GMapping table

A Known_source is a type of External_source. A Known_source is a Iso15926_4_rdl or a Otd_catalogue or a Otd_dictionary or a Plib_dictionary or a Plib_library.

EXPRESS specification:

*)
ENTITY Known_source
  ABSTRACT SUPERTYPE OF (ONEOF (Iso15926_4_rdl,
                                Otd_catalogue,
                                Otd_dictionary,
                                Plib_dictionary,
                                Plib_library))
  SUBTYPE OF (External_source);
END_ENTITY;
(*

4.3.3 Otd_catalogue   EXPRESS-GMapping table

An Otd_catalogue is a type of Known_source whose representation is defined in ISO/TS 22745-40.

EXPRESS specification:

*)
ENTITY Otd_catalogue
  SUBTYPE OF (Known_source);
END_ENTITY;
(*

4.3.4 Otd_dictionary   EXPRESS-GMapping table

An Otd_dictionary is a type of Known_source whose representation is defined in ISO/TS 22745-10.

EXPRESS specification:

*)
ENTITY Otd_dictionary
  SUBTYPE OF (Known_source);
END_ENTITY;
(*

4.3.5 Plib_dictionary   EXPRESS-GMapping table

An Plib_dictionary is a type of Known_source whose representation is defined in ISO 13584-25 (conformance classes 1-4).

EXPRESS specification:

*)
ENTITY Plib_dictionary
  SUBTYPE OF (Known_source);
END_ENTITY;
(*

4.3.6 Plib_library   EXPRESS-GMapping table

An Plib_library is a type of Known_source whose representation is defined in ISO 13584-25 (conformance classes 5-11).

EXPRESS specification:

*)
ENTITY Plib_library
  SUBTYPE OF (Known_source);
END_ENTITY;
(*

4.3.7 User_defined_library_or_dictionary   EXPRESS-GMapping table

An User_defined_library_or_dictionary is a type of External_source.

EXPRESS specification:

*)
ENTITY User_defined_library_or_dictionary
  SUBTYPE OF (External_source);
INVERSE
  source : External_source_identification FOR item;
END_ENTITY;
(*

Attribute definitions:

source: specifies an inverse relationship that specifies that the existence of the User_defined_library_or_dictionary is dependent on the existence of the External_source_identification that specifies the User_defined_library_or_dictionary as its item.

4.4 ARM subtype constraint definition

This subclause specifies the ARM subtype constraint for this module. The subtype constraint places a constraint on the possible super-type / subtype instantiations. The ARM subtype constraint and definition is specified below.

4.4.1 external_source_subtypes   EXPRESS-GMapping table

The external_source_subtypes constraint specifies a constraint that applies to instances of subtypes of External_source.

EXPRESS specification:

*)
SUBTYPE_CONSTRAINT external_source_subtypes FOR External_source;
  ONEOF (Known_source,
         User_defined_library_or_dictionary);
END_SUBTYPE_CONSTRAINT;
(*
