This section specifies the template representing_product_as_realized_structure.

NOTE The template has been defined in the context of the capability representing_product_as_individual which provides an overall description of the relevant parts of the ISO 10303-239 information model and a description of related templates.

NOTE An explanation of a template and the associated instantiation path is provided in the Template overview section.

Description

This template describes how to represent a structure of realized products.

Model diagrams

The EXPRESS-G diagram in Figure 1 shows the templates and EXPRESS entities that are required to represent the template "representing_product_as_realized_structure". The text highlighted in blue shows the template parameters.

Input parameters

The following input parameters are defined for this template:

parent (Type= 'ENTITY (Product_view_definition)' )

The parent Product_view_definition in the structure of Product_as_realized.

child (Type= 'ENTITY (Product_view_definition)' )

The child Product_view_definition in the structure of Product_as_realized.

Reference parameters

The following reference parameters are defined for this template:

view_def_usage(Type='ENTITY (View_definition_usage)')

Allow the View_definition_usage entity instantiated in this path to be referenced when this template is used.

Note: The View_definition_usage entity can be referenced in a template path by:

%^target = $representing_product_as_realized_structure.view_def_usage%

where target is the parameter to which the View_definition_usage is bound.

Instantiation path

The instantiation path shown below specifies the entities that are to be instantiated by the template.

A description of templates and the syntax for the instantiation path is provided in the Templates Help/Information section.

-- instantiate View_definition_usage
View_definition_usage
%^view_def_usage = View_definition_usage%
View_definition_usage.id = '/IGNORE'
View_definition_usage.relation_type = '/IGNORE'
View_definition_usage.description = '/IGNORE'
View_definition_usage.relating_view -> @parent
View_definition_usage.related_view -> @child

The following entities are instantiated with attributes as specified:

Entity in path	Value	Inherited from
View_definition_usage.id	'/IGNORE'	View_definition_relationship.id
View_definition_usage.relation_type	'/IGNORE'	View_definition_relationship.relation_type
View_definition_usage.description	'/IGNORE'	View_definition_relationship.description

Instance diagrams

The instance diagram in Figure 3 shows an example of the EXPRESS entities and templates that are instantiated by the template:

/representing_product_as_realized_structure(items='#1', class_name='Safety_critical', ecl_id='urn:plcs:rdl:std')/

(an illustration of the consolidated representing_product_as_realized_structure template is shown in Figure 4 below.)

Figure 3 — Entities instantiated by representing_product_as_realized_structure template

The instance model in STEP ASCII exchange file format (ISO 10303 Part 21 syntax) is:


          #1 = TASK_METHOD($,$,$,$,());
          #2 = EXTERNAL_CLASS('/IGNORE','Safety_critical',$,#3);
          #3 = EXTERNAL_CLASS_LIBRARY('urn:plcs:rdl:std',$);
          #4 = CLASSIFICATION_ASSIGNMENT(#2,(#1),'/IGNORE');

The instance model in STEP XML exchange file format (ISO 10303 Part 28 ed.2 syntax) is:

The instance diagram in Figure 4 shows the graphic symbol for the template that is to be used in other instance diagrams. The example template is:

/representing_product_as_realized_structure(items='#1', class_name='Safety_critical', ecl_id='urn:plcs:rdl:std')/

Characterizations

The following section details how the representing_product_as_realized_structure template can be optionally characterized by assigning other constructs to it. These are characterizations commonly applied to the template. The ISO 10303-239 EXPRESS model may enable other assignments to the entities instantiated by the template.

The EXPRESS-G diagram in Figure 5 shows the possible characterizations of the template "representing_product_as_realized_structure".

Figure 5 — Characterizations for representing_product_as_realized_structure

The following characterizations may apply:

Characterization Assigning date

NOTE this characterization is optional.

The date when the Work_order and the Directed_activity was issued can be represented by assigning a date (using the relationship Date_or_date_time_assignment) to the Work_order and the Directed_activity using the assigning_calendar_date template with the Date_time being classified as a type of "Date actual release" (urn:plcs:rdl:std:Date actual release).

NOTE The assignment of dates is described the capability C036: assigning_date_time.
