This section specifies the template activity_feedback_parameter.

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 measured activity feedback parameter.

Business perspective

The activity feedback parameter business object is used by those UK_Defence Data Exchange Specifications that require information about the measured activity feedback parameter.

Business object definition

Figure 1 — Graphical Representation for Business Object Activity Feedback Parameter

Activity Feedback Parameter:

The definition of an Activity Feedback Parameter object is: Data about the identification of the measured activity feedback parameter.

Attribute name	Attribute description	Attribute type	Optionality
Activity parameter	This is the unit of measure for the feedback parameter.	Relationship to Measure_with_unit	Mandatory
ID	This is the identifier of the Activity Feedback Parameter.	Identifier	Mandatory
Related activity feedback	This is a reference to the related Activity feedback .	Relationship to Activity Feedback	Mandatory

Model diagrams

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

activity_parameter_value (Type= 'TYPE (any_number_value)' )

The value of the measure for the feedback parameter.

activity_parameter_unit (Type='CLASS')

The class name corresponding to the unit of measure for the feedback parameter.

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

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

ID (Type='STRING')

This is the identifier of the Activity Feedback Parameter.

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_feedback (Type= 'ENTITY (Activity_actual)' )

This is the unit of measure for the feedback parameter.

Reference parameters

The following reference parameters are defined for this template:

act_fdbk_param(Type='ENTITY (Assigned_property)')

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

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

%^target = $activity_feedback_parameter.act_fdbk_param%

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

Uniqueness constraints

The following parameter combinations specify a uniqueness constraint:

Unique constraint: Activity Feedback Parameter

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

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.

    property_class_name='Activity_feedback_parameter',
    property_ecl_id='urn:plcs:rdl:uk_defence',

Instance diagrams

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

/activity_feedback_parameter(activity_parameter_value='ANY_NUMBER_VALUE(10)', activity_parameter_unit='Man_hour', ID='PUP123', source_organization='UK_Defence', related_activity_feedback='@124')/

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

Figure 4 — Entities instantiated by activity_feedback_parameter 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:

/activity_feedback_parameter(activity_parameter_value='ANY_NUMBER_VALUE(10)', activity_parameter_unit='Man_hour', ID='PUP123', source_organization='UK_Defence', related_activity_feedback='@124')/

Characterizations

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