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;
(*
The following EXPRESS interface statements specify the elements
imported from the ARMs of other application modules.
EXPRESS specification:

USE FROM
External_source_arm;

USE FROM
Plib_class_reference_arm;

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

(*
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.
An Iso15926_4_rdl is a type of
Known_source.
EXPRESS specification:
*)
ENTITY Iso15926_4_rdl
SUBTYPE OF (Known_source);
END_ENTITY;
(*
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.

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