Overview

An Valuelist is a managed list of values, similar to an SDMX Codelist but unlike a Code the Value Id does not need to conform to the SDMX ID Type.

Note: A Valuelist is not an official part of the SDMX Specification. It may be supported in version 3.0 of the standard, it is supported in version 10.2.0 of the Fusion Registry.

The schematic illustrates the how the Valuelist is used by Data Structure Definitions (DSD).

Note A valuelist is not an official part of the SDMX Information model at version 2.1, which is currently the latest model.

Usage

Valuelists provide an enumerated list of allowable values, for which there is also a mandatory Name and optional descirption. This list can be referneced for defining the set of allowed values for enumerated Components in Data Structure Definitions (DSDs) or Metadata Structure Definitions which describe Reference Metadata.

An example item would be the value $ with the name Dollar.

Conventions

'VL_' Valuelist ID Prefix

Valielist IDs are given a 'VL_' prefix to distinguish them from other structures. For instance: VL_CURRENCY.
