1) Public Review for version 2.0 of the SDMX Glossary

The SDMX Statistical Working Group would like to submit a new Version 2.0 of the SDMX Glossary.

This version 2.0 is a major version change due to the many new concepts and corrections to existing terms and the removal of concepts which are not used as part of reference metadata frameworks. The goal is to increase the usability and quality of the SDMX Glossary both as a central reference point for SDMX metadata, and for the Cross-Domain Concept Scheme (that is generated from the glossary) to cover more structural metadata enabling systems to align.

All concepts were reviewed to make descriptions and contexts clearer. Of particular note are:

  • The addition of “coverage” concepts
  • The addition of classification concepts used in Global DSDs, e.g. “Labour Force Status”, “Sector”
  • Make the “Measure” and “Statistical indicator” definitions more useful with examples for unambiguous use in modelling

The public review period for this document extends until 8 October 2018. Please send your comments to the SDMX Statistical Working Group at swg@sdmx.org.

2) Public Review for version 1.3.0 of the SDMX RESTful API

The SDMX Technical Working Group has produced a new version of the SDMX RESTful API and submits it for public review. Version 1.3.0 contains two new features, four improvements to existing features and several improvements to the documentation and the Wiki.

All changes can be viewed on GitHub:

The public review period for this specification extends until 30 September 2018. Please send your comments via email at twg@sdmx.org or report them on Github.

3) Public Review for the updated SDMX-JSON Data Exchange Format

The SDMX Technical Working Group (TWG) has updated the SDMX-JSON Data Exchange Format which is now made available for public review. This process will be open until 1 September 2018 (new deadline). Feedback is welcome before the deadline.

The SDMX-JSON standard is a JSON (JavaScript Object Notation) based data exchange message format designed for and therefore responding to the main use case of data discovery and visualisation on the web. The proposed format conforms to the JSON standard specification.

JSON is a widely used standardised lightweight data-interchange format. SDMX-JSON with a simple and dense but generic message format that supports different types of data structures will ease writing software for the web that easily consumes SDMX data resources. It should allow for an efficient client-server exchange with few roundtrips, small message sizes and fast parsing. The format may be used in a wide variety of programming languages and application programs. Testing and development of the format has focused on JavaScript applications running in web browsers.

The SDMX-JSON Data Message format supports the SDMX 2.1 Information Model and works together with the SDMX 2.1 RESTful Web Services API for data queries. The SDMX-JSON format is streamable from a supporting web service in order to limit the amount of server resources.

Please send your comments to the SDMX Technical Working Group (SDMX-TWG) at twg@sdmx.org. Changes can also be proposed by forking the Github repository and sending pull requests.
