ConceptScheme | Specific Item Schemes | Set of concepts that are used in a Data Structure Definition or Metadata Structure Definition. | Structural definitions of both data and reference metadata associate specific statistical concepts with their representations, whether textual, coded, etc. In SDMX these concepts are taken from a “concept scheme” which is maintained by a specific agency. Concept schemes group a set of concepts, provide their definitions and names. It is possible for a single concept scheme to be used both for data structures and metadata structures. A core representation of each concept can be specified (e.g. a code list, or other representations such as “date”). |
