Lexicon
PastPerfect's Lexicon is based on Nomenclature for Museum Cataloging, by Paul Bourcier, Heather Dunn, and the Nomenclature Task Force. We recommend you use the terms in the Lexicon as much as possible to keep your data entry consistent. However, it is possible to revise and add to the Lexicon to fit your organization's needs on the Setup Lexicon screen.
Access Lexicon Screen
1.Go to "Settings" on the Main Navigation Bar
2.Click "Lexicon"

Find Object Name
Use the Filter section at the top of the screen to find particular Lexicon entries. It is possible to filter on Category, Classification, Sub-Classification, Primary, Secondary, Tertiary, or Object Name. (The Object Name option will search across all three levels of object names – Primary, Secondary, and Tertiary.) You may combine multiple filters with AND or OR. Once the filter is applied, the resulting Lexicon entries will be displayed in the Results section. For more information, see Working with Filters.
