4.2.489 Specification_category

A Specification_category is the definition of a set of Specification objects serving the same purpose.

EXAMPLE The category 'kind of drive' for the Specification objects 'front wheel drive' and 'rear wheel drive' or the category 'level of equipment' for the Specification objects 'standard', 'comfortable', and 'luxurious' are examples for a Specification_category.

The data associated with a Specification_category are the following:

4.2.489.1 description

The description specifies information about the Specification_category.

EXAMPLE The description 'trim' characterizes a Specification_category for Specification objects that controls the quality and colour of the interior parts including e.g., inner door panels and upholstery. Other examples are 'kind of drive', 'rear brake type', 'brake power regulator', 'radio equipment', or 'type of car body'.

See specification_category to multi_language_string for the application assertion.

There shall be exactly one object that defines the description for a Specification_category.

4.2.489.2 id

The id specifies the identifier of the Specification_category that shall be unique.

NOTE The scope of uniqueness is usually dependent on the form of implementation.

EXAMPLE The scope of uniqueness may be set by the extent of a physical file or data base.

4.2.489.3 implicit_exclusive_condition

The implicit_exclusive_condition specifies whether the Specification objects within the Specification_category are mutually exclusive for the production of one particular product. A value of 'true' indicates that the referenced objects are mutually exclusive for the production of the particular product.

EXAMPLE 'safety equipment' is an example for a non mutually exclusive Specification_category if e.g. ABS and airbag are Specification objects in this category. 'engine' is an example for a Specification_category with an implicit_exclusive_condition since usually only one engine can be mounted for power supply.

NOTE More complex conditions can be handled using Specification_expression objects.
