A Classification is a system of categories, ordered according to a pre-determined set of principles and used to organize a set of instances or entities. This doesn't mean that the principles are always good or equitable or robust, and indeed, every classification is biased in one way or another (for example, compare the Library of Congress classification with the Dewey Decimal System)..  Classifications are embodied in every information-intensive activity or application.  Faceted or dimensional classification is especially useful in domains that don't have a primary hierarchical structure.
