  Abstraction, concretization, generalization, and specialization
 are operations on concepts.
 
 -Generalization: An existing description of a set of objects
 can be further generalized by adding new objects to the set 
 and modifying the description to take these objects into
 account.
 
 -Specialization: The inverse operation to generalization is
 specialization. Specializing the description of a set of
 objects involves the reduction of the set to a subset.
 
 -Abstraction: An existing description of a set of objects
 can be further abstracted using a new focus and filtering
 away all parts of the description that are not relevant
 with respect to the new focus.
 
 -Concretization: The inverse operation to abstraction is
 concretization (also called refinement). Concretization
 results in the increase of detail per objects.
