"The focus of CONA is works cataloged in scholarly literature, museum collections, visual resources collections, archives, libraries, and indexing projects with a primary emphasis on art, architecture, or archaeology. There are many fields in CONA, however through titles/names (equivalence relationships), as well as hierarchical and associative relationships, the basic structure of CONA is that of a thesaurus in compliance with ISO and NISO standards. Although it may be displayed as a list, CONA is a hierarchical database; its trees branch from a root called Top of the CONA hierarchy (Subject_ID: 700000000). There may be multiple broader contexts, making CONA polyhierarchical. In addition to the hierarchical relationships (e.g., between a print and the larger volume to which it belongs), CONA has equivalence relationships (between equivalent titles/names) and associative relationships (e.g., between a sketch and the final work). The primary top divisions of CONA are the facets Built Work and Movable Work. With the exception of performance art, CONA records unique physical works. However, CONA may include works that were never built or that no longer exist, for example designs for a building that was not constructed or a work that has been destroyed.
