A defined context defines the usage (use case) of data access. A context knows all its object types ([[MetaClasses]]) and the [[properties]] (columns) that are available in its context.
There might be different contexts scopes defined for read access and write access for the same MetaClass.
The contexts for a given [[ACM]] are defined by using a [[relation]] (“CONTEXT”).
Applications know their related [[ContextObjects]].
