Thesaurus module

The Thesaurus module stores one or more thesauri with lists of terms that can be added to Thesaurus-controlled fields in other modules (when describing or categorizing objects for instance). A Thesaurus-controlled field can be identified by the Thesaurus button beside it. A thesaurus can be used when searching, creating and editing records.

Fields in other modules can be attached to the Thesaurus and configured so that only valid terms (as defined in the thesaurus) will be accepted into the field. This ensures consistency in terms used to describe objects and facilitates searching.

It is possible to import a commercial thesaurus or to develop one in-house. Each thesaurus is identified by a unique acronym, e.g. AAT (Art Architecture Thesaurus), LCSH (Library of Congress Subject Headings).

The Thesaurus module has a Browse View that provides a hierarchical view of all loaded thesauri. The Thesaurus module includes a Thesaurus tab in the Ribbon with options when using the Browse View.

Hierarchy View

The Hierarchy View tab displays the expanded thesaurus hierarchy for a single term in a thesaurus (the current record). Unlike Browse View it:

does not display the current term's child terms;

only displays Use and Used for terms for the current term.

In this example, we see the expanded hierarchy of the current record, the Reciprocity term:

Multiple terms can be selected on the Hierarchy View tab using the CTRL or SHIFT keys while clicking with the mouse.

Right-click the Hierarchy View to access a menu with options for interacting with a term and, more generally, the hierarchy :

History

Term history details, including:

Change date
Person who made the changes to the term

A term in a thesaurus may have many different statuses. For example it may start as a candidate term, then become a valid term, then get moved in the thesaurus hierarchy and finally be retired by having a Use reference placed on it. Each of these changes may be recorded on the History tab. This provides the user with fields to record the date of change, to make notes regarding what change took place and to record who was responsible for authorizing the change. By adding to these fields each time a change is made to a term a complete history of that term can be recorded:
