A classifier is a namespace computer science namespace whose method computer science members can specify a generalization hierarchy by referencing its general classifiers. A classifier is a type and can own generalizations, thereby making it possible to define generalization relationships to other classifiers. A classifier is a redefinable element, as it is possible to redefine nested classifiers. All Object computer science objects that can have instances are classifiers.

When organizing source code, use packages to represent the different layers of the source code.
