Data Schema

There are three basic levels to a Reading Room object: object (the object as a whole), part (a distinct unit of an object), and contents (a specific title within a part). There is always one object to one or many parts, and one part to one or many contents, or items, as represented below in the schema or to the right in the visual skeleton.
