The following documentation is intended for developers. It is not necessary to understand this material in order to use or administer the Thesaurus module.

Note: Details about Thesaurus Registry entries are available here.

The Thesaurus module supports both single hierarchy and multi-hierarchy thesauri and has the ability to:

  • Define what validation should be performed when a term is entered into a field
  • Restrict entry of values into a field to be a sub-tree of a Thesaurus
  • Expand Thesaurus terms at query time
