This section specifies the template related_nato_specification.

NOTE The template has been defined in the context of UK_Defence. Refer to the business context for details 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 related Nato Item of Supply Specification object to an Item of Supply.

Business perspective

This information object represents a relationship between an Item of Supply and a Nato Item of Supply Specification. The former may be related to either a Product Specification or a Nato Item of Supply Specification.

Model diagrams

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

The graphic for the template to be used in other EXPRESS-G diagrams is shown in Figure 2 below.

Input parameters

The following input parameters are defined for this template:

item_of_supply (Type= 'ENTITY (Resource_item)' )

The refering Item of Supply

nato_item_of_supply_specification (Type= 'ENTITY (Resource_item)' )

The referenced Nato Item of Supply Specification.

Reference parameters

The following reference parameters are defined for this template:

ios_nato_ios_relationship(Type='ENTITY (Resource_item_relationship)')

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

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

%^target = $related_nato_specification.ios_nato_ios_relationship%

where target is the parameter to which the Resource_item_relationship 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.

-- Create the relationship entity
/representing_resource_item_relationship(
class_name='Item_of_supply_to_nato_ios',
ecl_id='urn:plcs:rdl:uk_defence')/
%^related_nato_specification = $representing_resource_item_relationship.res_item_rel%

-- Map the input parameters to those for rep_prom_usg, first is the top item
^related_nato_specification.related -> @nato_item_of_supply_specification
^related_nato_specification.relating -> @item_of_supply

Instance diagrams

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

/related_nato_specification(item_of_supply='@7', nato_item_of_supply_specification='@189')/

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

Figure 3 — Entities instantiated by related_nato_specification template

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:

/related_nato_specification(item_of_supply='@7', nato_item_of_supply_specification='@189')/

Characterizations

No common characterizations of the template related_nato_specification have been identified. However, the ISO 10303-239 EXPRESS model may enable other assignments to the entities instantiated by the template.
