Overview

An SDMX Codelist is a managed list of classification codes.

Structure Type Standard SDMX Structural Metadata Artefact

Usage

SDMX Codelists are lists of classification codes principally used for defining the set of allowed values for enumerated components in Data Structure Definitions or Metadata Structure Definitions.
Each code is treated as a separated Item so must have an ID and a Name, but can also have an optional Description. While Code IDs are unique within a Codelist, the same Code ID may be safely used in other Codelists. For instance: The code 'A' may be used in a Frequency Codelist to represent 'Annual', but also appear in an Industry Codelist to represent 'Agriculture'.

Conventions

CL_ Codelist ID Prefix

Codelist IDs are given a 'CL_' prefix to distinguish them from other structures. For instance: CL_FREQ, CL_REF_AREA, CL_AGE.

Code ID Conventions

Codes can take any legal SDMX ID. But there are several conventions in use:

Uppercase Code IDs By convention, Code ID's are in uppercase such as 'ABC'. Lower case Codes are valid (for example 'abc'), but care should be taken in their use to avoid confusion.
'_Z' Code The '_Z' code is conventionally used for the Undefined and Unknown classification.
'TOTAL' Code The 'TOTAL' code represents the total or sum of the dimension. For a 'country' dimension, series with TOTAL would indicate the sum of observation values for all countries included in the dataset.

Examples

A Simple Frequency Codelist: CL_FREQ

Code ID Code Name
A Annual
S Half-yearly, semester
Q Quarterly
M Monthly
W Weekly
D Daily
B Daily - Business Week
N Minutely
