Category Scheme V10

Overview

A Category Scheme is a container for Categories. An example of a category scheme is one which categorises data - sometimes known as subject matter domain scheme or a data category scheme. The individual Categories can be associated to any set of identifiable Artefacts in a Categorisation.
