INTRODUCTION

The SDMX technical standards are sufficiently generic to allow institutions to adopt and implement any specific representation. However, the use of common code lists would facilitate users to work even more efficiently as it eases the maintenance of, and reduces the need for, mapping systems and interfaces delivering data and metadata to users. Therefore, a choice over code lists has a great impact on the efficiency of data sharing.

For more general information about code lists, please refer to the “Introduction to the Content-oriented Guidelines”. For information about the construction of code lists, please refer to the “Guidelines for the Creation and Management of Cross-Domain Code Lists”. Both documents can be found under the “Guidelines” section of this site.

LIST OF AVAILABLE CROSS-DOMAIN CODE LISTS

This section lists the cross-domain code lists that have been officially adopted so far by the SDMX Secretariat based on proposals from the Statistical Working Group (SWG). The files below are generally made available in MS-Word or MS-Excel formats. The code lists can also be downloaded in SDMX-ML format from the following address: https://registry.sdmx.org/overview.html
