122 122  The ConceptScheme can have one or more Concepts. A Concept can have zero or more child Concepts, thus supporting a hierarchy of Concepts. Note that a child Concept can have only one parent Concept in this association. The purpose of the hierarchy is to relate concepts that have a semantic relationship: for example a Reporting_Country and Vis_a_Vis_Country may both have Country as a parent concept, or a CONTACT may have a PRIMARY_CONTACT as a child concept. It is not the purpose of such schemes to define reporting structures: these reporting structures are defined in the MetadataStructureDefinition.

124 -The Concept can be associated with a coreRepresentation. The coreRepresentation isthe specification of the format and value domain of the Concept when used on a structure like a DataStructureDefinition or a MetadataStructureDefinition, unless the specification of the Representation is overridden in the relevant structure definition. In a hierarchical ConceptScheme the Representation is inherited from the parent Concept unless overridden at the level of the child Concept.

126 126  Note that the ConceptScheme is used as the Representation of the MeasureDimension in a DataStructureDefinition (see 5.3.2). Each Concept in this ConceptScheme is a specific measure, each of which can be given a coreRepresentation. Thus the valid format of the observation for each measure when reported in a data set for the MeasureDimension is specified in the Concept. This allows a different format for each measure. This is covered in more detail in 5.3.
