4.2.431 Property_value_association

A Property_value_association is a mechanism to assign a Property_value_representation to an object.

Each Property_value_association is a Process_property_association or an Item_property_association.

The data associated with a Property_value_association are the following:

4.2.431.1 describing_property_value

The describing_property_value specifies the value that is being assigned.

See property_value_association to property_value_representation for the application assertion.

4.2.431.2 description

The description specifies additional information about the Property_value_association.

See property_value_association to multi_language_string for the application assertion.

The description need not be specified for a particular Property_value_association.

If present, there shall be exactly one object that defines the description for a Property_value_association.

4.2.431.3 validity_context

The validity_context specifies the context in which a Property_value_association is applicable.

EXAMPLE A Cost_property is applicable in the context of supplier A and may be different if the item is supplied by a different supplier B.

EXAMPLE     Software can be used in different product classes, specified by the validity_context, with different parameter values.

See property_value_association to organization, property_value_association to product_class, and property_value_association to product_identification for the application assertions.

The validity_context need not be specified for a particular Property_value_association.

If present, there shall be exactly one object that defines the validity_context for a Property_value_association.
