DSpace metadata not completely flat-- ability to use authority keys (part of 1.6 Authority Control feature). Can be used for LC Name Authority lookup. Also a place to store staff ID, ORCiD, etc. Currently useful as way to hover over value to see additional key or provide lookup. Also queryable when harvested. Integrated in submission form. For proper DCTERMS, would need to enforce use of that authority key for certain terms, and stored literal is more "eye candy" for display.
ContentDM based on DCTERMS? Or just Simple DC?
