CountryData Development

Improving the collation, availability and dissemination of development indicators (including the MDGs)

Nairobi, 27 November 2013

national database
National Database
  • Implemented in all project countries
  • Store and expose national development indicators
  • Provide a searchable Web interface over the data
  • Most project countries use the DevInfo software as the platform
  • Thailand and Morocco use native systems (StatXChange and BDS)
sdmx registry
SDMX Registry
  • Facilitates “pull model” for efficient data dissemination
  • Sends update notifications to subscribers
  • Enables automated data and metadata transfers
  • Implemented in 10 project countries
  • Most project countries use DevInfo 7 Registry
    • Thailand uses Metadata Technology’s Fusion Registry
devinfo 7
DevInfo 7
  • Released by DevInfo Support Group in November 2012.
  • Much improved over di 6: better user interface, visualizations, search
  • A number of tools developed for the project facilitate SDMX exchange
    • SDMX Registry
    • MDG DSD Mapping Tool
devinfo 7 recent developments
DevInfo 7: Recent Developments
  • A number of improvements recently implemented for the project by DSG
    • Advanced mappings (many-to-one and one-to-many)
    • Advanced publication filters
    • Simplified and improved menu structure
    • Improved SDMX functionality
thailand statxchange to countrydata
Thailand: StatXChange to CountryData
  • StatXChange is an advanced data sharing system developed by the Thailand NSO
    • Relies on Web services that supply data in an XML format (StatXML)
  • Application was developed with UNSD assistance that converts StatXML to MDG SDMX.
thailand sdmx registry
Thailand: SDMX Registry
  • Once converted, SDMX data is placed on a Web server and registered with Fusion Registry, installed with UNSD assistance.
  • Fusion Registry is an advanced implementation of the SDMX Registry specification, developed by Metadata Technology.
morocco sdmx export
Morocco: SDMX Export
  • Morocco uses its own indicator database, BDS, developed in-house.
  • Morocco NSO built SDMX export module, which produced SDMX data that has been published at CountryData.
  • Fusion Registry to be installed in December 2013 to complete the data exchange system.
countrydata platform
CountryData Platform
  • Developed by UNSD for the project
  • Automatically receives development data indicators from project countries
  • Enables comparisons between national data and those obtained from international agencies
  • Provides re-dissemination and data visualization
  • Part of, and linked to, UNdata

discrepancy analysis
Discrepancy Analysis
  • Once in the CountryData database, national development indicators are matched with international MDG series.
  • Any discrepancies are investigated and reported on the Web site.
  • Metadata crucial in explaining discrepancies.
visualization and re dissemination
Visualization and Re-dissemination
  • National and international development indicators are presented at CountryData in charts as well as a tabular format.
  • Data transferred to CountryData can be downloaded in a variety of formats including CSV, Excel, and SDMX.
application programming interface
Application Programming Interface
  • API was developed for CountryData and some other UNdata datasets in 2012
  • Based Eurostat’s SDMX Reference Infrastructure software
  • Uses SDMX to query for structures and data, and to receive results
  • Support for SDMX 2.1, as well as REST Web service, to be introduced soon
api how it works
API: How It Works

1. Request chart on a Web page

6. Create and return chart

2. Call SDMX Web Service

5. Return SDMX data

3. Query database

4. Retrieve data

further devinfo development
Further DevInfo Development
  • Work is underway on new di features
    • Installer for the di 7 software
    • Further improvements to SDMX publishing
expansion of data exchange
Expansion of Data Exchange
  • Mexico has supplied MDG indicators in the SDMX format, which has been published at CountryData.
  • Other countries have expressed interest in joining data exchange.
migration of legacy data
Migration of Legacy Data
  • Plans are in place to migrate the MDG Labs database into CountryData
    • MDG Labs was developed for the pilot phase of the UNSD-DfID project.
    • Shows discrepancy analysis for several dozen countries.
    • Does not support SDMX or data exchange. After migration, all its data will be downloadable as SDMX.
countrydata development
CountryData Development
  • New home page to accommodate non-project countries
  • New visualizations as part of UNdata redesign
dsd development
DSD Development
  • MDG DSD constantly updated, primarily with geographical information.
    • CountryData DSD v 0.9 in sync with latest MDG DSD
  • CountryData DSD to be updated with new indicators requested by countries.
  • Both DSDs to be updated for improved maintenance and compatibility with SDMX Reference Infrastructure.
  • MDG Labs (current version)

  • UNdata Web Service

  • UNdata SDMX Browser
