Application module: External library | ISO/TS 10303-1778:2014-02(E) © ISO |
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.

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.

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.

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.
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.
