This section specifies the template usage_role_phase_relationship.

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 the relationship between the PSE Constituent Usage Role and the Usage.

Business object definition

usage_role_phase_relationship

The definition of a usage_role_phase_relationship object is: This information object represents information about an actual usage_role_phase_relationship of an individual product.

Attribute name	Attribute description	Attribute type	Optionality
Related usage phase	This is a reference to the related Usage phase.	Relationship to Required PSE Constituent Usage Phase	Mandatory
Related usage role	This is a reference to the Usage role.	Relationship to Required PSE Constituent Usage Role	Mandatory
Sequence	This attribute specifies the position of the Usage phase in the sequence of Usage phases.	intrinsic	Mandatory

Input parameters

The following input parameters are defined for this template:

related_usage_phase (Type= 'ENTITY (Task_step)' )

This is a reference to the related Usage phase.

related_usage_role (Type= 'ENTITY (Task_method_version)' )

This is a reference to the Usage role.

sequence (Type='STRING')

This is the sequence number of the relationship.

source_organization (Type='STRING')

An Organization representing the sequence of the relationship.

Reference parameters

The following reference parameters are defined for this template:

usage_role_phase_relationship(Type='ENTITY (Task_element_assignment)')

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

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

%^target = $usage_role_phase_relationship.usage_role_phase_relationship%

where target is the parameter to which the Task_element_assignment 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 assignment to link the reqd_pse_cont_usg_profile
Task_element_assignment
Task_element_assignment.role = '/IGNORE'
Task_element_assignment.assigned_activity_method -> @related_usage_phase
Task_element_assignment.items -> @related_usage_role
%^usage_role_phase_relationship = Task_element_assignment%

-- sequence identifier
/identifier(
    ID=@sequence,
    source_organization=@source_organization,
    type='sequence_id_code',
    items=^usage_role_phase_relationship)/

The following entities are instantiated with attributes as specified:

Entity in path	Value	Inherited from
Task_element_assignment.role	'/IGNORE'	Applied_activity_method_assignment.role

Instance diagrams

The instance diagram in Figure 4 shows an example of the EXPRESS entities and templates that are instantiated by the template:

/usage_role_phase_relationship(related_usage_phase='#2', related_usage_role='#47', sequence='1', source_organization='6421')/

(an illustration of the consolidated usage_role_phase_relationship template is shown in Figure 5 below.)

The instance diagram in Figure 5 shows the graphic symbol for the template that is to be used in other instance diagrams. The example template is:

/usage_role_phase_relationship(related_usage_phase='#2', related_usage_role='#47', sequence='1', source_organization='6421')/

Characterizations

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