Defining Classification Values

A classification value is the actual name used in your organization for a particular item in the category represented by the classification level; for example, the name of a particular project in the Project level.

In a multilevel hierarchy, classification values have relations to logically related classification values in the levels above and below their level. Each classification value must have exactly one related term in the level above and may have zero or more related terms in the level below.

In a single-level hierarchy, classification values do not have defined relations with any other classification values. They may or may not be logically related to each other.

In the example above, the Term Uniqueness attribute of the Site level is set to Within Parent so that the same site can appear in the Site level more than once, related to more than one study. In the example, both General Hospital and Grace Hospital appear twice, for two different studies.
