4.2.290 Item_version

An Item_version is a version of an Item and serves as the collector of the data characterizing a physically realizable object in various application contexts.

NOTE 1 An Item_version may be produced, consumed, used to produce other Item_version objects, or offered to the market.

NOTE 2 The collection of defining information may be incomplete, i.e., not all of the Design_discipline_item_definition objects needed to define an Item_version are associated with the Item_version.

NOTE 3 The set of Item_version objects of an Item represents the history of the Item within a particular life cycle stage or over its complete life cycle.

NOTE 4 An Item_version does not have to be referenced by any Design_discipline_item_definition.

NOTE 5 In the case, where two Item_version objects are related to each other by an Item_version_relationship with a relation_type of value 'supplied part', the relating Item_version is the version carrying the necessary information, e.g., shape and properties, and the related is the version either supplied by or supplied for another company.

The data associated with an Item_version are the following:

4.2.290.1 associated_item

The associated_item specifies the Item with which the Item_version is associated.

See item_version to item for the application assertion.

4.2.290.2 description

The description specifies additional information about the Item_version.

See item_version to multi_language_string for the application assertion.

The description need not be specified for a particular Item_version.

If present, there shall be exactly one object that defines the description for an Item_version.

4.2.290.3 id

The id specifies the identifier of the Item_version. The id shall be unique within the scope of the associated Item.

NOTE A particular object is identified by the id of Item_version that serves to identify the particular version coupled with the id of the associated Item that serves to identify the generic object.
