Enumerated Values

For static enumerations, defining a new type involves:

Creating a new unique type name
Constructing a list of known values, each consisting of an internal value, and an optional display value

Note: Naming your new enum type int or integer does not cause any problems, however it can make maintenance of the metadata more difficult.

For query-based enumerations, define:

A mapping to an unmanaged class
The attributes the objects of that class have available for querying
An association between a managed class and unmanaged class, through an appropriately chosen attribute in the former class
