Concept Schemes and Concepts

Overview

Concept Schemes are a container for Concepts. Concepts are used by Dimensions, Attributes, Measures, and Metadata Attributes to provide them with a semantic meaning. Concepts can also be used to define a default representation, for example it is possible to link the Concept of Frequency to a Codelist containing all the Frequency Codes, any structure using the Concept will inherit the default representation.

The above shows the Concepts in a Concept Scheme, the image below shows how Concepts are used to give various Components of a Data Structure a name. Concepts can be used by any number of structures, and a structure (such as a DSD) can reference Concepts from any number of Concept Schemes.
