Depict-related search terms and indexes were removed by https://git.yale.edu/lux-its/marklogic/issues/933 and https://git.yale.edu/lux-its/marklogic/issues/934, respectively. Removed search terms included:

• depictedBy, from multiple scopes.
• depictsAgent
• depictsConcept
• depictsPlace

The scope of this ticket is to remove references / configuration for the above search terms from the following files as they are obsolete, cluster the files, and can cause confusion.

• relationNames.mjs
