111 111  The //DimensionComponent//, DataAttribute, and PrimaryMeasure link to the Concept that defines its name and semantic (/conceptIdentity association to Concept). The DataAttribute, Dimension, and MeasureDimension (but not TimeDimension) can optionally have a +conceptRole association with a Concept that identifies its role in the DataStructureDefinition. Therefore, the allowable roles of a Concept are maintained in a ConceptScheme. Examples of roles are: geography, entity, count, unit of measure. The use of these roles is to enable applications to process the data in a meaningful way (e.g. relating a dimension value to a mapping vector). It is expected that communities (such as the official statistics community) will harmonise these roles with their community so that data can be exchanged and shared in a meaningful way in the community.
