Input parameters

The following input parameters are defined for this template:

authorised_by (Type= 'ENTITY (Person)' )

This is the reference to the person that authorized the concession.

date_year (Type= 'TYPE (year_number)' )

Year_component of the date on which the concession is defined to start

date_month (Type= 'TYPE (month_in_year_number)' )

Month_component of the date on which the concession is defined to start

date_day (Type= 'TYPE (day_in_month_number)' )

Day_component of the date on which the concession is defined to start

ID (Type='STRING')

This is the identifier of the concession.

source_organization (Type='STRING')

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

ID_type (Type='CLASS')

This is the name of the type of the class used to classify the identifier and so provide the role or reason for the identification.

The following classes and their sub-classes can be used:

classifications: "Identifier_type" (urn:plcs:rdl:std:Identifier_type)

name (Type='STRING')

This is the name of the concession.

related_product (Type= 'ENTITY (Product)' )

This is the reference to the product(s) for which the concession has been raised

type (Default=Concession,Type='CLASS')

The type of the concession.

The following classes and their sub-classes can be used:

classifications: "Concession" (urn:plcs:rdl:std:Concession), [Deferment]

Error RDL4: The URI urn:plcs:rdl:uk_defence is not listed in dexlib/data/refdata/rdl_index.xml
[Dispatch_deviation]

Error RDL4: The URI urn:plcs:rdl:uk_defence is not listed in dexlib/data/refdata/rdl_index.xml

related_activity (Type= 'ENTITY (Activity_actual)' )

The reference to the activity that is deferred.

Reference parameters

The following reference parameters are defined for this template:

approval(Type='ENTITY (Approval)')

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

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

%^target = $activity_deferment.approval%

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

Uniqueness constraints

The following parameter combinations specify a uniqueness constraint:

Unique constraint: Unique id

Each instance of the entity (Approval) within the data set shall be uniquely identified by a combination of the following parameters on this template (activity_deferment) namely: ID, name, type.
The instance is referenced by the following template parameter: approval.

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.

/concession(
    authorised_by=@authorised_by,
    date_year=@date_year,
    date_month=@date_month,
    date_day=@date_day,
    ID=@ID,
    source_organization=@source_organization,
    ID_type=@ID_type,
    name=@name,
    related_product=@related_product,
    type=@type)/
%^approval = $concession.approval%
Approval_assignment

-- Bind the Approval_assignment to the parameter ^approval_assgn.
-- The parameter is a reference parameter so the Approval_assignment
-- entity can be referred to when this template is used.
%^approval_assgn = Approval_assignment%
Approval_assignment.role = '/IGNORE'
Approval_assignment.items -> @related_activity
Approval_assignment.assigned_approval -> ^approval

The following entities are instantiated with attributes as specified:

Entity in path	Value	Inherited from
Approval_assignment.role	'/IGNORE'	—

Instance diagrams

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

/activity_deferment(authorised_by='#67', date_year='2008', date_month='3', date_day='5', ID='con123', source_organization='BAE Systems', ID_type='Identification_code', name='RH drive con', related_product='#85', type='Concession', related_activity='#391')/

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