Usage
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 that should be taken into account when choosing Code IDs:
| Uppercase | 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. |
