CorrespondenceType¶
Describes the commonalities and differences between two items using a textual description of both commonalities and differences plus an optional coding of the type of commonality, a commonality expresses as a 0 to 1 weighting factor (expressing degree of comparability) and a user defined correspondence property which is specific to an organization or community of use.

A brief description describing the commonality of the two schemes/items, i.e., “Identical”, “High”, “Medium”, “Low”, “None”. Supports the use of an external controlled vocabulary. The DDI Alliance has provided a controlled vocabulary (CommonalityType) to support this element at http://www.ddialliance.org/controlled-vocabularies. |

A value between 0 and 1 expressing the degree of commonality (0 indicates none, 1 indicates that they are identical). |

An alternate means of expressing commonality within a specific system. A system specific user defined correspondence expressed as a key/value pair. As this is specific to an individual system the use of controlled vocabularies for the key is strongly recommended. |
