Towards Implementation of SDMX
9-11 January 2007
Statistical subject-matter domains
Lars Thygesen, OECD
January 2007
Objective
No data collection necessary
No “central” repository or database
– a virtual database
Sharing in real time
Anyone could access
– if authorised
January 2007
Same mechanism intra-nationally
2
Metadata – a must for
international statistics
Find the data
Understand comparability
Concepts, definitions, data quality
Recommended uses
Reference metadata
January 2007
3
National statistical metadata
systems
Multiple audiences
– Staff (e.g. statistician, developer, manager)
– Internal or external users of the statistics (e.g.
editors, news media, analysts, policy decision
makers)
Structural metadata
Reference metadata
– Conceptual metadata
– Methodological metadata,
– Quality metadata
January 2007
4
Metadata systems of
international organisations
January 2007
concepts, definitions of concepts,
measurement units, transformations
delimitation of populations
dimensions of quality (e.g. sample sizes,
standard errors on estimates, other
sources of errors
5
SDMX – the link between national and
international frameworks
cubes
structural metadata
DSD
reference metadata relating to cubes
attachment levels
MSD
terminology MCV
themes Statistical Subject-Matter
Domains
January 2007
6
Towards a generic model
each organisation has its own theme
structure and terminology
we all make data available on web
how can users go across domains
(organisations)?
how can they find what they want?
how can we exchange data & metadata?
January 2007
7
A scenario for data sharing
a user wants data from Mexico, Uganda
and OECD
on GDP per capita
goes to the registry
how to find the domain?
Statistical Subject-Matter Domains
January 2007

Statistical Subject-Matter Domains
Identical to UNECE classification of
activities
created with partly the same objective
It is not perfect
No perfect classification exists
It is used and clear
It can be mapped
January 2007
– “we call it so-and-so”
– ‘we want this to be at level 1”
– is it easy to agree on themes in your
organisation?

Who should develop DSDs?
Who can be responsible?
International organisation
– if one leading organisation
Inter-secretariat groups
– e.g. ISWGNA
January 2007
How can we ensure coherence across
DSDs?
Conceptual analysis
14
Summing up
Statistical subject-matter domains for:
thematic structure for presenting data
links in registry
organising the development of SDMX
DSDs and MSDs
