Template:— representing_organization_typical (rep_org_typ) Date: 2008/02/27 16:39:46
Revision: 1.10

This section specifies the template representing_organization_typical.

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 type of organization, e.g. line of maintenance.

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

Input parameters
The following input parameters are defined for this template:
org_type_class_name (Type='CLASS')
The name of the External_class that determines the organization type being referenced.
The following classes and their sub-classes can be used:
classifications: "Organization_type" (urn:plcs:rdl:std:Organization_type)
org_type_ecl_id (Default=urn:plcs:rdl:std,Type='URN')
The identification of the External_class_library storing the External_class given by the input parameter @org_type_class_name.
Reference parameters
The following reference parameters are defined for this template:
org_type(Type='ENTITY (Organization_type)')
Allow the Organization_type entity instantiated in this path to be referenced when this template is used.
Note: The Organization_type entity can be referenced in a template path by:
%^target = $representing_organization_typical.org_type%
where target is the parameter to which the Organization_type is bound.
Uniqueness constraints

The following parameter combinations specify a uniqueness constraint:
Unique constraint: Organization type
Each instance of the entity (Organization_type) within the data set shall be uniquely identified by a combination of the following parameters on this template (representing_organization_typical) namely: org_type_class_name, org_type_ecl_id.
The instance is referenced by the following template parameter: org_type.
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.
Organization_type

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

-- provide the type of organization by classifying the entity Organization_type
/assigning_reference_data(
    items=^org_type,
    class_name=@org_type_class_name,
    ecl_id=@org_type_ecl_id)/
The following entities are instantiated with attributes as specified:
Entity in path Value Inherited from
Organization_type.name '/IGNORE'
Organization_type.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:
/representing_organization_typical(org_type_class_name='First-line_maintenance', org_type_ecl_id='urn:plcs:rdl:sample')/
(an illustration of the consolidated representing_organization_typical template is shown in Figure 4 below.)

Figure 3 —  Entities instantiated by representing_organization_typical template

The instance model in STEP ASCII exchange file format (ISO 10303 Part 21 syntax) is:
#1 = ORGANIZATION_TYPE('/IGNORE','/IGNORE'); #3 = CLASSIFICATION_ASSIGNMENT(#5,(#1),'/IGNORE'); #5 = EXTERNAL_CLASS('/NULL','First-line_maintenance','/IGNORE',#6); #6 = EXTERNAL_CLASS_LIBRARY('urn:plcs:rdl:sample',$);
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:
/representing_organization_typical(org_type_class_name='First-line_maintenance', org_type_ecl_id='urn:plcs:rdl:sample')/

Characterizations
The following section details how the representing_organization_typical 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 following characterizations may apply:
Characterization Assigning descriptor

NOTE   this characterization is optional.

Additional descriptions, notes etc for the defined Organization_type may be assigned using the assigning_descriptor template.
