This section specifies the template representing_work_request.

NOTE The template has been defined in the context of the capability representing_work_request 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 a work request.

Model diagrams

The EXPRESS-G diagram in Figure 1 shows the templates and EXPRESS entities that are required to represent the template "representing_work_request". The text highlighted in blue shows the template parameters.

Figure 1 — An EXPRESS-G representation of the Information model for representing_work_request

The graphic for the template to be used in other EXPRESS-G diagrams is shown in Figure 2 below.

Note, either a person or an organization must be associated with the Work_request using the templates assigning_person_in_organization or assigning_organization respectively.

Instance diagrams

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

/representing_work_request(id='Issue 134', id_class_name='Work_request_identification_code', id_ecl_id='urn:plcs:rdl:std', org_id='BikeRent Limited', org_id_class_name='Organization_name', org_id_ecl_id='urn:plcs:rdl:std', version_id='v1', version_id_class_name='Version_identification_code', version_id_ecl_id='urn:plcs:rdl:std', version_org_id='BikeRent Limited', version_org_id_class_name='Organization_name', version_org_id_ecl_id='urn:plcs:rdl:std', date_class_name='Date_actual_creation', date_ecl_id='urn:plcs:rdl:std', year='2006', month='6', day='8', hour='14', minute='0', second='0', sense='EXACT', hour_offset='0', minute_offset='0', state_class_name='Work_request_issued', state_ecl_id='urn:plcs:rdl:std', purpose='Safety_issue', purp_ecl_id='urn:plcs:rdl:sample')/

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

Note that the mandatory characterization by the templates assigning_descriptor and assigning_person_in_organization is shown in the diagram. Namely:

@43 /assigning_person_in_organization(last_name='Olsen', first_name='Bob', person_role_class_name='Issuer_of', person_role_ecl_id='urn:plcs:rdl:std', org_id='BikeRent Limited', org_id_class_name='Organization_name', org_id_ecl_id='urn:plcs:rdl:std')/

and:

@68 /assigning_descriptor(descr='Brakes keep jamming', class_name='descr', ecl_id='urn:plcs:rdl:std')/

Characterizations

The following section details how the representing_work_request 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 "representing_work_request".

Figure 5 — Characterizations for representing_work_request template

The following characterizations may apply:

Characterization Assigning person or organization

NOTE this characterization is mandatory.

The person or organization that raised the issue must be assigned to the Work_request by Person_in_organization or Organization (using the relationship Organization_or_person_in_organization_assignment) The assignment is defined by the templates assigning_organization and assigning_person_in_organization respectively.

Characterization Assigning documentation

NOTE this characterization is optional.

A text string providing a description of the Work_request is represented by the template assigning_descriptor. If more documentation is necessary to describe the issue, documents can be assigned using the Document_assignment relationship as described in the template assigning_document.

Characterization Assigning dates

NOTE this characterization is optional.

Dates can be associated with the work request by using the template assigning_calendar_date.

Characterization Approvals

NOTE this characterization is optional.

The approval status of the Work_request is represented by assigning_approval.
