THE MISSION OF INSTAT

• INSTAT s mission is to produce objective,
  impartial, reliable, professional independence,
  relevance, transparence and timely statistics
  that help the user to judge on the developments
  of the transformation processes in our country.

The vision of INSTAT

• As only used statistics are useful statistics,
  INSTAT strives to become
• the major source of statistical information
  providing decision makers, research and education
  in Albania
• in the international community with relevant,
  reliable and comparable statistical information.
• with a learning attitude and systematic network
  for marketing and disseminating statistical
  information making use of modern networking
  structures and information technology

Metadata strategy

• Collection of information about the data
  collected in an application or database.
• Decide how meta data would be used in the
  organization
• Decide who would use what meta data and why
• Develop map for managing statistical information
  from different sources
• Improve the quality of statistics produced

6
Purpose of metadata

• The main purpose of statistical metadata is to
  inform users of statistical data about
• which statistical data are available
• where to find and how to retrieve certain
  statistical data that they need
• how to interpret statistical data, once they are
  available

7
Current situation

• Implementation a metadata model based on Official
  Statistical Program (PSZ).
• At that moment the SCBDOC was considering as the
  only suitable model to be used as a template.
• INSTAT has made some successful pilots for
  metadata based on Official Statistics Program
  (PSZ).

8
Current situation (cont 1)

• From statistical point of view
• INSTAT has made some successful pilots based on
  Official Statistical Program (PSZ).
• The first one was prepared for Business
  Statistics activities as well as SBS,
  STS-survey, STS-building permits, Foreign trade
  statistics, Tourism statistics, Transport
  statistics

9
Current situation (cont 2)

• From IT point of view
• IT sector has developed the AlbMeta application
  which is a application used for describing a
  physical database for a micro data register. The
  development tools used are all from Microsoft
  SQL Server 2005 and Visual Basic.NET.

PSZ organization (cont)

• 3 Final observation registers
• 3.1 Production versions
• 3.2 Long-term (archive, terminal) storage
  versions
• 3.3 Experiences from the latest survey round
• 4 Statistical processing and presentation
• 4.1 Estimation assumptions and calculation
  formulas
• 4.2 Presentation procedures
• 5 Data processing system
• 6 Log file

13
Cost and Benefits

• Cost
• Hard work for describing the PSZ
• Hard work between IT staff and statistician
• Every thing is done parallel with daily work
• Benefits
• Hopefully produced statistics in standard way and
  process oriented way
• To be more efficient

14
Implementation strategy

• One important aspect is to develop a system for
  documentation of micro data that has an improved
  functionality and higher quality of the content
  of current AlbMeta.
• The system is going to work together with other
  parts of the metadata system.
• The system will
• Provide an overview of metadata for the micro
  data.
• Provide information for evaluating the
  possibilities for matching data from different
  surveys or other sources.
• Operate as a tool for increased standardisation
  and harmonisation and therefore give better
  possibilities for data coordination.
• Provide a better support for documenting so that
  the overall quality of the documentations can be
  increased.

15
Practical work

• The system is going to be an important tool for a
  large part of Institute of Statistics.
• Therefore user groups consisting of interested
  persons were tied to the project from the
  beginning.
• The user groups were categorised in
  statisticians, methodologists and system
  developers.
• These groups took an active part in developing
  the content and functionality of the system in
  order to be a useful tool for them in their
  practical work.
• Other requirements have also been collected by
  the project group and taken into account when
  developing the system.

16
Project Organisation

• The metadata group is composed from the IT,
  Business Statistics, Methodology and Business
  Register staff and LTC from Statistics Sweden.

17
Metadata sources

• The main sources that Institute of Statistics
  used for collecting and producing the statistical
  data are
• Statistical surveys
• Administrative sources.
• The metadata is organizing in direction of those
  two main sources. For the moment there is no real
  data in the database system.

18
Metadata used

• The only metadata managed at this stage is for
  the developing and designing phase. The project
  is planning to introduce PC Axis as a
  dissemination tool from a macro database.
