SDMX Standards Version 2.1 (original release April 2011)

The final version of SDMX 2.1 has been released on 18 April 2011, after a public review period and approval by the SDMX sponsoring organisations. The amendments to the SDMX 2.0 standards represent a substantial enhancement to the way SDMX operates, without increasing complexity and with the intention of making it easier to implement. This new release corrects some bugs, adds requested functionalities and includes a stronger alignment of the XML schemas with the information model.

SDMX Standards Version 2.0

SDMX Technical Standards Version 2.0 provide the technical specifications for the exchange of data and metadata based on a common information model. The scope of this work is to define formats for the exchange of aggregated statistical data and the metadata needed to understand how the data is structured. The major focus is on data presented as time series, although cross-sectional XML formats are also supported.

Version 2.0 Technical Standards are backward compatible with the earlier Version 1.0 work, which focused on XML- and EDIFACT-syntax data formats. The latest work broadens the technical framework to support wider coverage of metadata exchange as well as a more detailed architecture for data and metadata exchange.

These specifications have been developed, reviewed, and adopted by SDMX. Steps will be taken to bring this work forward within the context of the International Standards Organisation (ISO), with a view to updating ISO/Technical Specification 17369:2005 SDMX.

 

SDMX Standards Version 1.0

The SDMX Standards Version 1.0 provide the technical specification for a set of XML-and EDIFACT-syntax data formats based on a common information model. The scope of this work is to define formats for the exchange of aggregated statistical data and the metadata needed to understand how the data is structured. The major focus is on data presented as time series, although cross-sectional XML formats are also supported.
These specifications have been developed, reviewed, and adopted by SDMX. In due course they will be put forward to the International Standards Organisation (ISO) for adoption.
