To utilize a thesaurus and the controlled vocabulary functionality while indexing in OHMS, a thesaurus must be uploaded and linked to the record in the metadata utility. These thesauri contain terms that will be auto-suggested in the keyword and subject fields of the indexing module. This practice helps to manage consistency in titles and descriptive terms. Thesauri can be assigned for the following fields in the interview index:
Thesauri must be uploaded as a single-column .CSV file. See of this guide for specifics regarding formatting your .csv file. The “Subject” thesaurus can utilize a “Linked” version of the Library of Congress Subject Headings. Headings have been harvested via the Library of Congress Linked Data service and become an optional thesaurus for the “Subjects” fields in the Indexing Module. You do not need to upload anything to utilize this functionality. You just need to assign the “Library of Congress Subject Headings (Linked) in the “Thesaurus (Subjects) field of that particular record in the Metadata Module.
