Joint Adb – Unescap Sdmx Capacity Building Initiative Sdmx Starter Kit for National Statistical Agencies JOINT ADB – UNESCAP SDMX CAPACITY BUILDING INITIATIVE SDMX STARTER KIT FOR NATIONAL STATISTICAL AGENCIES Version: 5 October 2014 1 FOREWORD The aim of the Starter Kit is to provide a resource for national statistical agencies in countries in the Asia and Pacific region contemplating the implementation of the Statistical Data and Metadata Exchange (SDMX) technical standards and content-oriented guidelines for the exchange of aggregate data and their related methodological information (metadata). It outlines a structured process for the implementation of SDMX by agencies that have little knowledge about SDMX and how they would go about the implementation of the standards and guidelines. In order to avoid duplicating the work of the SDMX sponsoring agencies the Kit makes extensive use of links to existing SDMX background documents and artifacts that have been developed at the global level. The Starter Kit was developed under the auspices of the joint 2014 Asian Development Bank– United Nations Economic and Social Commission for Asia and the Pacific SDMX initiative to improve the efficiency of data and metadata exchange between national statistical agencies in the Asia and Pacific region and international organizations through the ongoing use of SDMX standards. The aim of the joint initiative is to build the capacity of countries in the region to apply SDMX standards through mapping national concepts to specific identified SDMX Data Structure Definitions (DSDs) and Metadata Structure Definitions (MSDs). The initiative also aims at enabling national agencies to determine which, of a range of available tools for SDMX implementation, best meets the needs of the organisation. The basic premise of the Kit is that SDMX implementation must be seen in the context of a wide range of corporate institutional, infrastructure and statistical initiatives currently underway in almost all statistical agencies around the globe to improve the quality and relevance of the service they provide to government and non-government users of their outputs. Such corporate initiatives are often undertaken within the framework of a national strategy for the development of statistics (NSDS), statistical master plans or similar strategic planning process. A number of corporate initiatives relevant to SDMX are outlined in the Implementation Plan for the Regional Programme for the Improvement of Economic Statistics in Asia and the Pacific endorsed by the ESCAP Committee on Statistics in December 2012. Planned improvements from the Implementation Plan covered areas such as advocacy, coordination, statistical infrastructures, and skills. SDMX implementation entails considerable use of resources, expertise and effort at the national level and these will only be forthcoming if a substantive business case of the potential benefits can be made for SDMX implementation, particularly in the context of both broader national strategic goals and alternative technical standards. The Starter Kit presents the business case for SDMX implementation from the perspectives of both international and national statistical agencies. The intended audience are senior management in national agencies as well as statistical subject matter experts. The business case outlined was derived from NSDSs that have been prepared by countries in the Asia and Pacific region which are available on the Paris21 website and websites of several other national statistical organisations in the region. The final key theme throughout the Starter Kit is that SDMX implementation by national statistical agencies is not just an IT issue but one that requires close collaboration between different parts of the organisation, in particular, management and statisticians working in the domains being implemented. The intended broad national audience for the kit therefore includes, national statistical agency: management; statistical domain specialists; coordination units; data dissemination units; and IT specialists. The current version of the Starter Kit is still very much work in progress and feedback and suggested improvements from other international organisations and national statistical agencies are welcomed. Some of the information on current and proposed SDMX implementations at both the global and national levels will be relocated onto the web where they can be updated more readily as new information becomes available. 2 CONTENTS A.

It also provides a description of a training course on the Basics of SDMX, scheduled for GCC-Stat. 1 SDMX in short SDMX provides support for things that are important to statisticians and are often difficult for them to achieve, and it enables tools to be developed to provide support for these things. It does this by providing standard, well-designed formats for holding all of the elements involved in the statistical process and linking them all together in a clear model. The result is an approach that maximises the amount of metadata and statistical context information that can be passed through to statistical clients, maximises the possibility of relating statistics from similar or different sources, and allows for the automation of processes that are often difficult and costly to manage otherwise.

  • SDMX Roadmap 2021-2025
    SDMX Roadmap 2021-2025 Executive Summary The Statistical Data and Metadata eXchange (SDMX) is a standard developed to facilitate the exchange of data and metadata in the international statistical community. It is widely used by international organizations, national statistical offices, and other data producing agencies. The development of SDMX is guided by a roadmap that sets forth the objectives for a span of five years. The SDMX Roadmap 2021-2025 (“the Roadmap”) provides a strategic plan for the continuous development of SDMX over the next five years. The Roadmap has two main drivers: addressing a broadening set of needs and improving the usability of the standard. These two drivers come together under the umbrella of the SDMX 3.0 project. The new roadmap continues to group the objectives into four pillars: (i) Implementation, (ii) Simplification, (iii) Modernisation and (iv) Communication. The Roadmap aims to strengthen the implementation of SDMX. SDMX will be expanded to new statistical domains. Existing SDMX packages will be upgraded based on updates of international classification standards. The adoption of established global code-lists and data structure definitions (DSDs) will be encouraged. Finally, SDMX tools will be finalized to facilitate the exchange of referential metadata. Simplification will be required to facilitate the use of SDMX. Main directions of work will be to simplify referential metadata exchange mechanisms, explore links between SDMX and other standards, and develop tools that simplify the complexities of SDMX for novice users. SDMX will be leveraged to modernise statistical processes and IT infrastructure. The development of SDMX 3.0 will incorporate modern features of data management.

  • Annex 1 Technology Architecture 1 Source Layer
    Annex 1 Technology Architecture The Technology Architecture is the combined set of software, hardware and networks able to develop and support IT services. This is a high-level map or plan of the information assets in an organization, including the physical design of the building that holds the hardware. This annex is intended to be an overview of software packages existing on the market or developed on request in NSIs in order to describe the solutions that would meet NSI needs, implement S-DWH concept and provide the necessary functionality for each S-DWH level. 1 Source layer The Source layer is the level in which we locate all the activities related to storing and managing internal or external data sources. Internal data are from direct data capturing carried out by CAWI, CAPI or CATI while external data are from administrative archives, for example from Customs Agencies, Revenue Agencies, Chambers of Commerce, Social Security Institutes. Generally, data from direct surveys are well-structured so they can flow directly into the integration layer. This is because NSIs have full control of their own applications. Differently, data from others institution’s archives must come into the S-DWH with their metadata in order to be read correctly. In the early days extracting data from source systems, transforming and loading the data to the target data warehouse was done by writing complex codes which with the advent of efficient tools was an inefficient way to process large volumes of complex data in a timely manner. Nowadays ETL (Extract, Transform and Load) is essential component used to load data into data warehouses from the external sources.

  • (I) Functions of Metadata in Statistical Production
    The SDMX Istat Framework. Prepared by Mauro Bianchi, Dario Camol and Laura Vignola, ISTAT, Italy I. INTRODUCTION ISTAT in the two last years have been involved in several Eurostat SDMX projects the Eurostat SODI project, "Demography Pilot Project" and recently to the "Census Hub Pilot Project". The experience acquired during those projects has brought the development team in building the SDMX Framework. The idea was to create a new environment to manage the entire data flow that conducts to the reporting of data and reference metadata in SDMX format. The SDMX Framework, released as open source package, is composed by building blocks that can be also used separately, so that other statistical agencies can re-use and integrate them in their environments II. ARCHITECTURE A. The data framework The framework is composed by modules and classes that permit the user to create the environment, load data, create SDMX data file in compact and cross sectional format and the corresponding RSS (pull method without a web service) and make available data by a web service. 1.2 Manager The application Manager is a Client-Server application that creates the structure of the database. This structure is “SDMX compliant” that is the tables created inside the database contains as object the elements belong to the information model of SDMX (concepts, descriptors, code lists, key families). These tables are populated using the structure files, containing the Data Structure Definitions and all the information contained in these files are stored in specific tables created in the first loading and updated in every future loading if necessary.

  • The SDMX Service Architecture for the Perspective of a National Statistical
    Meeting of the Joint OECD/UNECE Expert Group on Statistical Data and Metadata Exchange 8-9 March Palais des Nations, UNECE, Geneva, Switzerland The SDMX service architecture for the perspective of a National Statistical Institute Prepared by [Francesco Rizzo, ISTAT Italy; Adam Wronski, Eurostat; Bengt-Ake Lindblad, Eurostat] I. Introduction 1. For several years the SDMX Sponsor Organisations have been developing software and tools in order to facilitate the introduction of SDMX in their countries. 2. Eurostat has been discussing the effectiveness of these tools with the Member States (MSs) during task forces meetings and working groups. Many suggestions from the MSs were collected which led in 2009 to an internal project named "SDMX implementation and support for Member States". The aim of that project was to develop a set of software, organized in re-usable building blocks and tools to help MSs in implementing an SDMX service infrastructure for a more efficient participation to some SDMX projects currently running within the European Statistical System (e.g. European Census Hub project). 3. A prototype was presented during the "Statistics, Telematic Networks & EDI" Working Group (STNE) in June 2009. The participants welcomed with enthusiasm the initiative and encouraged Eurostat to proceed forward. 4. The main objectives of the project can be listed as follows: (a) To support for the Census Hub project and other Eurostat projects; (b) To facilitate SDMX implementations within the MSs with a particular attention to the large PC- AXIS community; (c) To stimulate a "SDMX community of developer". 5. The project deliverables consist essentially of: (a) the SDMX NSI Reference infrastructure document.
