Property translation : Set(Iv3CD); (Read/Write)

Class Iv3CD

A set of other CDs that each represent a translation of this CD into equivalent codes within the same code system or into corresponding concepts from other code systems.

The translations are quasi-synonyms of one real-world concept. Every translation in the set is supposed to express the same meaning "in other words." However, exact synonymy rarely exists between two structurally different coding systems. For this reason, not all of the translations will be equally exact.

Translations SHALL NOT contain translations. The root CD has one set of translations which lists all the translations. The root translation is generally the one that best meets the conformance criteria for the CD. No implication about lineage of the translations can be drawn from the selection of the root code. Instead the properties codingRationale and source is used to trace lineage.

In the absence of a constraining model that makes constraints on the value domain of the CD, any of the translations MAY be the root CD. If the constraining model makes constraints on the value domain of the CD and there is a translation that meets the constraints, that translation SHOULD be the root CD. If the constraining model makes constraints on the value domain of the CD and there is no translation that meets the constraints, then any of the translations MAY be the root, as long as they are assigned a nullFlavor. An alternative is to put none of the translations in the root, and give it a nullFlavor of choice, and put all the translations in the translation property of the root.
