CountryData DSD

Single DSD used for all MDG (and other development indicators) - superset of MDG DSD

Using cross-domain concepts and codelists: Frequency (CL_FREQ) Sex (CL_SEX) Age (CL_AGE) (modified) Unit multiplier (CL_UNIT_MULT)

CountryData DSD

Support for diverse indicators means not all dimensions are applicable in all cases

e.g. Age Group is not applicable to indicator “Telephone lines”

Value NA is used when a dimension or attribute is not applicable.

CountryData DSD: Mappings

Not always obvious which values should be used in some dimensions

What should be SEX in indicator “Births attended by skilled health personnel”: Female? Total? Not Applicable?

What about the AGE dimension?

INDICATOR SERIES UNIT SEX AGE LOCATIONBirths attended by skilled health personnel SH_STA_BRTC Percent ?? ?? Total NA NA

CountryData DSD: Mappings (2)

Inconsistent mappings lead to duplications and other anomalies

In CountryData, mappings for time series are agreed before data exchange

For the MDG dataset, there has been a spreadsheet developed with the recommended mappings for each time series

CountryData DSD: Maintenance

CountryData codelists are maintained by UNSD

Periodically, the DSD needs to be updated A new version of the CountryData DSD (1.4),

with modified codelists, was released in January 2014

DevInfo 7

DevInfo 7 (Di7) launched in Nov 2012 SDMX 2.1 & 2.0 compliant Web-based software Most countries have migrated to version 7 from

version 6 DevInfo Support Group has been adding

enhancements and bugfixes; newest version is 7.1.0.1

Mapping to the DSD (in DevInfo)

The DevInfo mapping tool is designed to facilitate the mapping of the database to the DSD based on mapping between the codelists of the

DSD and origin database certain situations require further manual effort to

map a time series sometimes a “fix” is required to the database where

the data simply isn’t valid or where there are duplicates

Area, hierarchical dimension IUS = Indicator, Unit and Subgroup

Time series data are stored with the combination of the 3 dimensions Indicator Unit Subgroup: Combination of one or more sub-dimensions

Source & Time Period Together with IUS “uniquely” defines each data value

Footnote “Free text” field stored with data value

DevInfo Data Architecture

Step 1: (C) Map Age subgroup

Step 1: (D) Map Area

Step 1: Save codelist mappings

Step 1: Ignore warning

Step 1: Confirm mapping saved

Step 1: Complete

Exercise 1: Codelist mapping

Use unstats.un.org/demoginfo[1-6]

Map the codelists (where possible) for: Just one indicator, “Antenatal care coverage for at least

one visit” Unit Age Sex Location Area

Step 2: Confirm IUS mapping

Step 2: Save IUS Mappings

Why is Step 2 necessary?

The default values for SEX, LOCATION or AGE GROUP mapping may not be applicable to all mappings

The codelist mapping may only provide a partial mapping of the time series (i.e. more information is required)

Any necessary mapping changes are made in Step 2

Where are the default values?

Default Values• Age Group = 000_099_Y• Sex = T

• So subgroups coverage affects the number of manual changes which have to be made…

Step 2: Amend IndicatorWhen using the check box to tick the mapping, you are “fixing” the mapped DSD values. If the box is unchecked again and the mappings saved, then DSD values revert to those mapped at codelist / default values (i.e. any manual changes are undone.)

Exercise 2: Mapping time series

Use unstats.un.org/demoginfo[1-6] Username = [email protected] Password = 1234

Map the time series for1. “Literacy rate of 15-24 year-olds”

2. “Condom use at last high risk sex (Version 2)”

3. “Land under forest cover”

Final Step: Register mappings

Final Step: Generate SDMX-ML

Final Step: Complete

Complex SDMX Cases

Complex mappings under the 1st and 2nd mapping steps

Most commonly mappings need to be overridden for dimensions Sex, Age Group and Location

But sometimes manual changes are required between DevInfo and DSD indicator and unit, such as when… More than one DevInfo code relates to a single DSD

code OR More than one DSD code relates to a single DevInfo

Other issues encountered with generating SDMX from DevInfo

Type NameDimension SeriesDimension Units of measurementDimension LocationDimension Age groupDimension SexDimension Reference AreaDimension Time Period

• The CountryData DSD requires any data point to be uniquely described by the following dimensions:

• However, DevInfo allows data to be stored in overlapping time intervals and with multiple sources. These issues need to be resolved to conform to the “uniqueness” required by the CountryData DSD.

Multiple sources

Infant mortality rate PER_1000_LIVE_BIRTHS T 000_001_Y T

• This issue is only a problem where overlapping periods begin from the same year, as the mapping tool takes the first year in the period as the value for the “Time Period” dimension.

Targets in the database

Targets are also an issue when found in the database since they should not be exchanged as observed values

Use of filters at registration

To deal with the issues of multiple sources for a given time period overlapping time period beginning with the same

year targets presented alongside observed values

The registration page provides a feature to filter out data from a generated SDMX message associated with specific time periods and source references

Filter by time/ source

Final Step: Select source filter

Filter by time

Final Step: Select time filter

Final Step: Register new mappings

Final Step: Complete

Exercise 4: Filter time series


Map/ amend/ publish the time series for;1. “Under-five mortality rate”

2. “Maternal mortality ratio (MMR)”

3. “Tuberculosis prevalence rate”

4. “Proportion of the population using improved sanitation facilities”

New features in DevInfo 7.1

Improved Quick Data Search

Database updates and publishingAfter updating your database with new data, you can optimize and publish the updates in SDMX at the same time in Admin Panel

Database updates and publishing

DevInfo installation and upgrading

The latest version of DevInfo is 7.1.0.1 Starting with this version, you no longer need to

uninstall and reinstall in order to upgrade Instead you will use patches available on the DevInfo
