This section specifies the template referencing_product_group.
NOTE
The template has been defined in the context of the capability
representing_product_configuration
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.
This template describes how to represent a reference to a product group by its identification,
i.e. by using the identification data of a product group a reference to that product group can be made.
The EXPRESS-G diagram in
Figure
1
shows the templates and EXPRESS entities that are required
to represent the template
"referencing_product_group".
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

below.

The following input parameters are defined for this template:
The name of the class used to classify the product group identifier (@prod_grp_id) and to provide the role or reason for the
identification.
The following classes and their sub-classes can be used:
The identifier of the
Organization that "owns"
the product group identifier.
The name of the class that determines the type of identifier being used for identifying the
Organization. For example CAGE code.
The following classes and their sub-classes can be used:
The id of the
External_class_library storing the
definition of the class used to classify the organization identifier.
The following reference parameters are defined for this template:
Allow the
Product_group
entity instantiated in this path to be referenced when this template is used.
Note: The
Product_group
entity can be referenced in a template path by:
%^target = $referencing_product_group.prod_grp%
where
target
is the parameter to which the
Product_group
is bound.
The following parameter combinations specify a uniqueness constraint:
Unique constraint: Product_group
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.
The following entities are instantiated with attributes as specified:
The instance diagram in Figure
3
shows an example of the EXPRESS entities and templates that are instantiated by the template:
/referencing_product_group(prod_grp_id='200-299', prod_grp_id_class='Block_identification', prod_grp_id_ecl_id='urn:plcs:rdl:sample', prod_grp_org_id='Bike Ltd', prod_grp_org_id_class='Organization_name', prod_grp_org_id_ecl_id='urn:plcs:rdl:std')/
(an illustration of the consolidated referencing_product_group template is shown in
Figure
4 below.)

The instance model in STEP ASCII exchange file format (ISO 10303 Part
21 syntax) is:
#1 = PRODUCT_GROUP('/IGNORE','/IGNORE','/IGNORE','/IGNORE','/IGNORE');
#4 = IDENTIFICATION_ASSIGNMENT('200-299','/IGNORE',$,(#1));
#6 = CLASSIFICATION_ASSIGNMENT(#8,(#4),'/IGNORE');
#8 = EXTERNAL_CLASS('/NULL','Block_identification,'/IGNORE',#9);
#9 = EXTERNAL_CLASS_LIBRARY('urn:plcs:rdl:sample',$);
#11 = ORGANIZATION('/IGNORE','/IGNORE');
#13 = IDENTIFICATION_ASSIGNMENT('Bike Ltd','/IGNORE','/IGNORE',(#11));
#15 = CLASSIFICATION_ASSIGNMENT(#17,(#13),'/IGNORE');
#17 = EXTERNAL_CLASS('/NULL','Organization_name','/IGNORE',#18);
#18 = EXTERNAL_CLASS_LIBRARY('urn:plcs:rdl:std',$);
#19 = ORGANIZATION_OR_PERSON_IN_ORGANIZATION_ASSIGNMENT(#11,'/IGNORE',(#4));
#21 = CLASSIFICATION_ASSIGNMENT(#23,(#19),'/IGNORE');
#23 = EXTERNAL_CLASS('/NULL','Owner_of','/IGNORE',#18);
The instance model in STEP XML exchange file format (ISO 10303 Part

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:
/referencing_product_group(prod_grp_id='200-299', prod_grp_id_class='Block_identification', prod_grp_id_ecl_id='urn:plcs:rdl:sample', prod_grp_org_id='Bike Ltd', prod_grp_org_id_class='Organization_name', prod_grp_org_id_ecl_id='urn:plcs:rdl:std')/

The following section details how the
referencing_product_group
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 identification
NOTE this characterization is optional.
