This section specifies the template assigning_work_output.

NOTE The template has been defined in the context of the capability representing_activity which provides an overall description of the relevant parts of the ISO 10303-239 information model and a description 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 output from work that has been done.

NOTE The outputs referred to here are items that do not affect the configuration status of the product that have been worked on.

Model diagrams

The EXPRESS-G diagram in Figure 1 shows the templates and EXPRESS entities that are required to represent the template "assigning_work_output". 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:

class_name (Type='CLASS')

The class name corresponding to the type of the Work_output. For example, oil, Gypsum, swarf etc.

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

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

ecl_id (Default=urn:plcs:rdl:std,Type='URN')

The identifier of the External_class_library storing the definition of the class referenced by the parameter @class_name.

activity_item (Type= 'SELECT (work_item)' )

The activity that gave or will give rise to the Work_output.

Reference parameters

The following reference parameters are defined for this template:

work_asg(Type='ENTITY (Work_output_assignment)')

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

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

%^target = $assigning_work_output.work_asg%

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

work_output(Type='ENTITY (Work_output)')

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

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

%^target = $assigning_work_output.work_output%

where target is the parameter to which the Work_output 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.

Work_output_assignment

-- Mark the Work_output entity as
-- referable when this template is used by binding it to the reference
-- parameter work_output
%^work_asg = Work_output_assignment%
Work_output_assignment.item -> @activity_item
Work_output_assignment.assigned_output -> Work_output

-- Mark the Work_output entity as
-- referable when this template is used by binding it to the reference
-- parameter work_output
%^work_output = Work_output%
Work_output.name = '/IGNORE'
Work_output.description = '/IGNORE'

-- Assign reference data for type of Work_output
/assigning_reference_data(
    items=^work_output,
    class_name=@class_name,
    ecl_id=@ecl_id)/

The following entities are instantiated with attributes as specified:

Entity in path	Value	Inherited from
Work_output.name	'/IGNORE'	—
Work_output.description	'/IGNORE'	—

Instance diagrams

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

/assigning_work_output(activity_item='#2', class_name='oil', ecl_id='urn:plcs:rdl:sample')/

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

Figure 3 — Entities instantiated by assigning_work_output 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:

/assigning_work_output(activity_item='#2', class_name='oil', ecl_id='urn:plcs:rdl:sample')/

Characterizations

The following section details how the assigning_work_output template can be optionally characterized by assigning other constructs to it. These are characterizations commonly applied to the template. The ISO 10303-239 EXPRESS model may enable other assignments to the entities instantiated by the template.

The EXPRESS-G diagram in Figure 5 shows the possible characterizations of the template "assigning_work_output".

Figure 5 — Characterizations for assigning_work_output

The following characterizations may apply:

Characterization Assigning Identification

NOTE this characterization is optional.

Identifiers can be associated with the work output by using the template assigning_identification to assign an identifier to a Work_output as shown in Figure 5.

Characterization Representing Quantity

NOTE this characterization is optional.

Quantities can be associated with the work output by using the template representing_quantity through the optional quantity attribute on Work_output as shown in Figure 5.
