Version 2.1

The new SDMX User Guide provides guidance to the users on the version 2.1 of the Technical Specification released in 2011.

As version 2.1 of SDMX contains several innovative parts (such as web services guidelines, revised data messages, partial code lists and new metadata management) this User Guide intends to document how the new standard can be used to fulfil the most typical use cases and scenarios for data and metadata exchange.

The emphasis, throughout the guide, is on practical use of SDMX, supported by examples. In addition to the examples in the text, some sections of the User Guide refer to files which are available as a separate annex. Other paragraphs or annexes, oriented to a non-technical audience, could be added; therefore, it is expected that further revised drafts will follow, in the next months, also responding to needs expressed by readers.

Comments are welcome and can be sent to the SDMX Secretariat ( indicating the version of the User Guide to which comments refer.


The SDMX 2.0 User Guide aims to provide practical explanations and guidance to users and potential users of SDMX.

To complement the User Guide, contributed documents provide additional in-depth tutorials and guidance on SDMX.

Version 2009.1 is the second release of the SDMX 2.0 User Guide as a complete document. In this release, the material has been separated into two main parts:

Part A — the core thread — aims to explain SDMX in a non-technical way, dealing with the use of SDMX at all stages of the production and dissemination of statistics. This part of the User Guide should be accessible to statisticians without any special knowledge of or interest in informatics.

Part B — the tutorial thread — is aimed at readers who want more in-depth technical information on SDMX. It assumes that the reader wants to work with, or at least to understand, the information technologies which underlie SDMX.

Of course, many readers will want to look at both parts of the User Guide, which has been structured to make it easy for readers to work through the core thread while, if they wish, seeking further explanations or examples in specific chapters of the tutorial thread.

The emphasis throughout the User Guide is on the practical use of SDMX, supported by examples. No prior knowledge of SDMX is assumed.
