Content Classes are created as "conceptual wrappers." The wrappers logically group together thematically-related Elements (metadata fields and their attributes and properties). Content Classes exist at the top levels of a hierarchy of elements and element containers.

UMAP maintains 13 Content Classes as the conceptual wrappers for its various metadata elements:

01	Collections
02	Subjects: Curriculum & Academic Disciplines
03	Keyword Descriptions
04	Titles
05	Relationships
06	Technical: Media Types, Manifestations, Renditions, Locations & IDs
07	Utilization: Content Suitability for Audiences
08	Accessibility Options
09	Rights and Use Restrictions
10	Lifecycle
11	Meta-Metadata
12	vCard
13	Telescope Video Manager

To learn more about each UMAP Content Class and its description, link to our web page in the UMAP User Guide: Logical Groupings (Content Classes)(Option 3).

Content Classes enhance the ability to visualize and understand the hierarchical structure of a data dictionary and its associated data models. This hierarchical structure is easily viewed by observing a Graphical Illustration of the UMAP Elements, their interdependencies within Element Containers, housed within their Content Classes.
