Describes the degree of similarity between two items or schemes (collections of items).
| Value of the Code | Descriptive Term of the Code | Definition of the Code |
|---|---|---|
| Identical | Identical | Use when the compared items have identical content. For variables, for example, all the elements of a variable description (name, label, question text, category values and codes, universe, concept) will be identical in form. |
| Some | Some | Use when the compared items have similar but not identical content. For variables, for example, some of the elements of a variable description (name, label, question text, category values and codes, universe, concept) will be identical in form, while others will be different. |
| None | None | Normally not used, as it would not be expected to compare items that have nothing in common. This term was necessary to complete the commonality range, and may be used in special cases, as determined by user needs (for instance, when comparability was expected, but not found). |
The degree of commonality can also be expressed using the machine-actionable elements CommonalityWeight, UserDefinedCorrespondenceProperty, and the descriptive element Commonality.
