4.2.10 Alternate_item_relationship

An Alternate_item_relationship is the relationship between two Item objects specifying that all versions of the alternate Item may be used in place of the base Item, regardless of its usages and of its versions.

NOTE This concept usually refers to form, fit, function, and quality. Additional properties such as performance, noise, endurance, or reliability may also be considered as a prerequisite for the replacement.

The data associated with an Alternate_item_relationship are the following:

4.2.10.1 alternate

The alternate specifies the Item that may be used in place of the base Item.

See alternate_item_relationship to item for the application assertion.

4.2.10.2 base

The base specifies the Item for which another Item may be used as a replacement.

See alternate_item_relationship to item for the application assertion.

4.2.10.3 fulfilled_requirements

The fulfilled_requirements specifies the word or group of words describing the requirements that are covered by both the base and the alternate and therefore are the basis for the statement regarding the capability of replacement.

See alternate_item_relationship to multi_language_string for the application assertion.

There shall be exactly one object that defines the fulfilled_requirements for an Alternate_item_relationship.
