Application module: System identification and version | ISO/WD 10303-1484 |
This clause specifies the information requirements for the System identification and version 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 System_identification_and_version_arm schema and identifies the necessary external references.
EXPRESS specification:
*)
SCHEMA System_identification_and_version_arm;
(*
The following EXPRESS interface statements specify the elements imported from the ARMs of other application modules.
EXPRESS specification:
*)
USE FROM
Alias_identification_arm;
--

USE FROM
Product_version_relationship_arm;

NOTE 1 The schemas referenced above are specified in the following part of ISO 10303:
Alias_identification_arm ISO/TS 10303-1025 Product_version_relationship_arm ISO/TS 10303-1020
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 system_and_version_identification_item type is an extension of the alias_identification_item type. It adds the data types System and System_version to the list of alternate data types.
EXPRESS specification:
*)
TYPE
system_and_version_identification_item =
SELECT
BASED_ON
alias_identification_item
WITH
(System,
System_version);
END_TYPE;
(*
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.
NOTE 1 The concept system is any thing - matter, energy, organisation or information or a combination of these - for which reproducible measurements exist. The concept system excludes any asserted thing based on personal experience for which no reproducible measurements exist.
NOTE 2 SEDRES Definition: "An assembly of interacting, active components or elements forming a whole".
NOTE 3 Another definition would be "That which is discernable by reproducable measurement of its characteristics, and has a defined boundary (statically and dynamically) with respect to the universe".
EXPRESS specification:
*)
ENTITY System
SUBTYPE OF (Product);
END_ENTITY;
(*
NOTE In this case, this means "revision". So for a given system (e.g. a fuel injection system) we may have several versions of the system design (e.g. v1, v1.1 etc.)
EXPRESS specification:
*)
ENTITY System_version
SUBTYPE OF (Product_version);
SELF\Product_version.of_product : System;
END_ENTITY;
(*
Attribute definitions:
of_product: the System of which the System_version specifies a version.
EXPRESS specification:
*)
ENTITY System_version_sequence
SUBTYPE OF (Product_version_relationship);
SELF\Product_version_relationship.relating_version RENAMED predecessor : System_version;
SELF\Product_version_relationship.related_version RENAMED successor : System_version;
END_ENTITY;
(*
Attribute definitions:
predecessor: the previous System_version in the relationship.
successor: the succeeding System_version in the relationship.
