Public Review Announcement for new SDMX-JSON Data Exchange Format

The SDMX Technical Working Group (SDMX-TWG) has produced a new specification for the SDMX-JSON Data Message and submits it for public review.

JSON (JavaScript Object Notation) is a widely used standardised lightweight data-interchange format. The SDMX-JSON Data Message works together with the SDMX RESTful Web Services API. It will assist developers to write software that requests data responses in JSON from SDMX RESTful API and processes data and metadata in the JSON response. The current version of SDMX-JSON Data Message focuses on data visualisation and it supports all features of the SDMX RESTful API for data queries. SDMX RESTful API also supports reference metadata queries and structural metadata queries. These are not yet supported by the SDMX-JSON format.

The proposed format conforms to the JSON standard specification, and it supports the SDMX 2.1 Information Model. SDMX-JSON is streamable from a supporting web service in order to limit the amount of server resources. It should provide fast responses from a web service: few roundtrips, small message sizes and fast parsing. In addition, the format aims to ease the development of client applications with a simple but generic message structure that supports different types of data structures. The SDMX-JSON 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 public review period for this specification extends until 31st October 2014 in order to allow time for implementation. Please send your comments to the SDMX Technical Working Group (SDMX-TWG) twg@sdmx.org. Each email message should contain only one comment. Feedback is welcome.

SDMX Expert Group Meeting 2014

The next SDMX Expert Group meeting will be held in Korea from 27 to 30 October 2014.

The meeting will focus on a number of areas, including:

  • exchange of statistical data and metadata actually taking place or being implemented between organisations;
  • work being carried out by the SDMX Technical and Statistical Working Groups;
  • software developments which take advantage of SDMX standards;
  • progress of SDMX standards, guidelines and tools, especially the content-oriented guidelines and the user guide. The role of the SDMX global registry, including use case examples;
  • the role of SDMX in standards-based modernisation of official statistics and related work being carried out by the High-Level Group for the Modernisation of Statistical Production and Services (HLG).

The meeting will also include a capacity building training session for statisticians and IT staff on how to implement an SDMX architecture for reporting and dissemination. The course will have a hands-on approach based on case studies related to the National Accounts and OECD STES (Short-Term Economic Statistics) data collections.

4th SDMX Global Conference of September 2013: Summary report

Please find here the short summary report of the 4th SDMX Global Conference: “Global SDMX Implementation: Modernising Official Statistics”.

This conference took place in September 2013 in Paris, France.

 

SDMX Global Conference 2013, OECD, Paris

Global SDMX Implementation: Modernising Official Statistics

The next SDMX Global Conference will be held from 11 to 13 September 2013 at the OECD in Paris, with BIS and Eurostat acting as co-hosts on behalf of the SDMX Sponsors. The theme of this year’s conference is the global SDMX implementation and the role that SDMX can play in modernising official statistics. The conference will respond to the information needs of statistical managers and SDMX users to implement and maximise the value of adopting SDMX in data exchange. National statistical agencies, central banks and international organisations will share their experiences and expertise using SDMX in the collection and dissemination of official statistics.

Topics to be covered in the SDMX Global Conference 2013 include, for example, the application of SDMX in concrete data collection exercises such as national accounts, and the associated benefits of data and metadata integration and streamlining of national and international data exchange. The SDMX Sponsors will report on the progress of the SDMX technical and statistical standards and on the improved SDMX IT infrastructure including the implementation of the SDMX Global Registry. The conference will also provide an opportunity for the participants to explore the relationship between the SDMX business process models for statistics with other related technical standards.

As the conference aims to monitor the actual and planned use of SDMX in national and international organisations responsible for official statistics, we kindly ask you to fill in the SDMX Global Survey 2013 under following link: SDMX Global Survey 2013
