This section specifies the template role_change.

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 of an activity to the resulting product role change configuration

Business perspective

The role change business object is used by those UK_Defence Data Exchange Specifications that require information about the relationship between an activity and the product role configuration.

Business object definition

Role Change:

The definition of a Role Change object is: Data about the relationship between an activity and the product role configuration.

Attribute name	Attribute description	Attribute type	Optionality
ID	This is the identifier of the role change relationship	Identifier	Mandatory
Related_activity	This is a reference to the related Activity.	Relationship to Activity	Mandatory
Related product role configuration	This is a reference to the related product role configuration	Relationship to Product_Role_Configuration	Mandatory

Model diagrams

The EXPRESS-G diagram in Figure 2 shows the templates and EXPRESS entities that are required to represent the template "role_change". 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 3 below.

Input parameters

The following input parameters are defined for this template:

ID (Type='STRING')

This is the identifier of the role change relationship.

source_organization (Type='STRING')

The organization that created the identifier. Additionally a Person or Information System could be defined when either of these are the source; see Identifier template.

related_activity (Type= 'ENTITY (Activity)' )

This is a reference to the related Activity

related_product_role_configuration (Type= 'ENTITY (Product_configuration)' )

This is a reference to the related product role configuration.

Reference parameters

The following reference parameters are defined for this template:

rol_chg(Type='ENTITY (Applied_activity_assignment)')

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

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

%^target = $role_change.rol_chg%

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

Uniqueness constraints

The following parameter combinations specify a uniqueness constraint:

Unique constraint: Role_Change

Each instance of the entity (Applied_activity_assignment) within the data set shall be uniquely identified by the following parameters on this template (role_change) namely: ID.
The instance is referenced by the following template parameter: rol_chg.

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.

-- assigning_activity
/assigning_activity(
    role_class_name='Role_change',
    role_ecl_id='urn:plcs:rdl:uk_defence',
    assigned_activity=@related_activity,
    items=@related_product_role_configuration)/
%^rol_chg = $assigning_activity.appl_act%

-- ID (mandatory)
/identifier(
    ID=@ID,
    source_organization=@source_organization,
    type='Role_change_identifier',
    items=^rol_chg)/

Instance diagrams

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

/role_change(ID='RC123', source_organization='UK_Defence', related_activity='@2', related_product_role_configuration='@117')/

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

Figure 4 — Entities instantiated by role_change template

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:

/role_change(ID='RC123', source_organization='UK_Defence', related_activity='@2', related_product_role_configuration='@117')/

Characterizations

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