Application module: Characterizable object | ISO/TS 10303-1765:2019(E) © ISO |
This clause specifies the information requirements for the Characterizable object 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 Characterizable_object_arm schema and identifies the necessary external references.
EXPRESS specification:

SCHEMA Characterizable_object_arm;

NOTE 2 See Annex C, Figures C.1and C.2 for a graphical representation of this schema.
This subclause specifies the ARM types for this application module. The ARM types and definitions are specified below.

END_TYPE;
(*
Enumerated item definitions:
unspecified: the kind of shape is not specified.
The co_activity_item type is an extension of the activity_item type. It adds the data type Characterizable_object to the list of alternate data types.
EXPRESS specification:
*)
TYPE
co_activity_item =
SELECT
BASED_ON

(Characterizable_object);
END_TYPE;

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.
A Characterizable_object is an object that may be characterized with properties but cannot be considered as a product or an activity.
EXAMPLE 1 An orbit of a satellite is an example of Characterizable_object.
NOTE A Characterizable_object may be used as an environmental condition under which the properties of a product are measured.
EXAMPLE 2 If a product has a set of properties that are measured within a particular atmosphere, the atmosphere may be described with an instance of the entity data type Characterizable_object.
