resource_property

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 numerical value range for a resource property.

The following input parameters are defined for this template:

The following reference parameters are defined for this template:

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.

-- Instantiate Resource_property_representation entity
Resource_property_representation

-- Bind the Resource_property_representation entity to reference parameter ^prop_repr
%^prop_repr = Resource_property_representation%

-- Set the Property_representation attributes role and description to be ignored
^prop_repr.role = '/IGNORE'
^prop_repr.description = '/IGNORE'

-- Instantiate template representing_value_range
/representing_value_range(
    upper_limit=@upper_limit,
    lower_limit=@lower_limit,
    unit=@unit,
    unit_ecl_id=@unit_ecl_id,
    si_unit=@si_unit,
    context=@context,
    context_ecl_id=@context_ecl_id)/

-- Bind the Property_value_representation entity instantiated in the template representing_value_range
-- to ^representation in this template and assign Resource_property_representation.rep to it
%^representation = $representing_value_range.representation%
^prop_repr.rep -> ^representation

-- Assign value range to property
^prop_repr.property -> @property

The following entities are instantiated with attributes as specified:

Entity in path	Value	Inherited from
Resource_property_representation.role	'/IGNORE'	—
Resource_property_representation.description	'/IGNORE'	—

The following section details how the resource_property_range 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 representation role

NOTE this characterization is optional.

A role or definition method can be associated with the property representation by using the template assigning_reference_data assigned to Resource_property_representation (reference parameter ^prop_repr).

Figure 6 — Characterization by role of resource_property_range template

Characterization Assigning date and time

NOTE this characterization is optional.

Dates can be associated with the assignment of property value representation by using the templates assigning_time.

Figure 7 — Characterization by date of resource_property_range template

A creation date is commonly assigned to the template resource_property_range.

The date of creation of the property value representation is represented by using the template assigning_time to assign a date and time to Property_value_representation (reference parameter ^representation in template representing_value_range). The date and time assignment is classified as: "Date actual creation" (urn:plcs:rdl:std:Date actual creation) to indicate that it is the date (and time) when the property value representation was actually created. This is illustrated in Figure 7.

Other dates may be assigned instead.

Characterization Assigning organization or person

NOTE this characterization is optional.

An Organization or a Person_in_organization can be associated with the property value representation by using the templates assigning_organization, or assigning_person_in_organization.

Figure 8 — Characterization by organization of resource_property_range template

A common role in which an organization is assigned to a property value representation is as a "Creator of" the representation. The creating organization is represented by using the template assigning_organization or assigning_person_in_organization assigned to Property_value_representation (reference parameter ^representation in template representing_value_range). The assignment of the organization (Organization_or_person_in_organization_assignment) is classified as: "Creator of" (urn:plcs:rdl:std:Creator of) to indicate that this organization created the property value representation. This is illustrated in Figure 8.

Other roles of an organization with regard to a property value representation may be assigned instead.
