2. Overview • Organization • Metadata Strategy • Statistical metadata system • Statistical metadata in each phase of the statistical business process • Systems and design issues • Organizational and workplace culture issues • Lessons learned

3. Organization The National Statistical System • Statistical Council • National Statistical Institute (Statistics Portugal)

4. The Statistical Council is the state body that supervises and coordinates the National Statistical System. Organization This duty is carried out by the “Planning, Coordination and Dissemination” Standing Section, which has the power: “…to analyse and approve concepts, definitions, nomenclatures and other technical instruments of statistical coordination of the National Statistical System and to approve regular changes to these documents resulting from work done at the EU or national level”(Structure and Functioning of Statistical Council – SC Deliberation No. 286; 2005).

5. Organization Statistics Portugal: • Record, • Refine, • Coordinate, • Disseminate, official data • Delegate duties to other public departments, • Conceive and manage the statistical metadata system of the National Statistical System.

6. Organization Statistical Council Secretariat Board Delegations (Porto, Coimbra, Évora, Faro) Planning, Control and Quality Unit Dissemination Unit Legal Support Unit Communication and Image Unit Administration and Management Department National Accounts Department Methodology and Information System Department Economic Statistics Department Demographic and Social Statistics Department Data Collection Department

7. Organization Methodology and Information System Department ....... Metadata Unit Applications Development Unit Coordinates all the work related to the statistical metadata system.

8. Metadata Strategy Approval of concepts Statistics Portugal centralises the management of statistical concepts. Concepts classified by subject area and, entered into database with the status “proposed concept”. The working groups (Statistical Council) analyse and recommend the concepts for approval to the Planning, Coordination and Dissemination Standing Section. After approval, the concepts receive the status: “Statistical Council – approved concept” and, are of obligatory use.

9. Metadata Strategy Approval of classifications: • Portuguese Classification of Economic Activities, • National Classification of Occupations, • National Classification of Goods and Services, • Administrative Division Code, • List of Countries, • Etc. Approved by the Statistical Council formandatory usein theNational Statistical System.

10. Metadata Strategy Approval of methodological documentation: 2005 Statistics Portugal submitted to appreciation to the Planning, Coordination and Dissemination Standing Section a standard format for the methodological documentfor theNational Statistical System’s surveys. The standard format was approved and adopted as mandatory in the National Statistical System. 2007 75% of the surveys in the National Statistical System were documented in this format.

13. Metadata Strategy Technical approval of surveys: • Thepreliminary methodological documentand thequestionnaire(s)are sent: • units directly involved, • users of the results of surveys, • Planning Unit, • Data Collection Department, • Methodology and Information Systems Department. opinion • The Metadata Unit analyses: • concepts and classifications, • ensures correct application of the standard format of the methodological document, • analyses questionnaires, • introduces new concepts into the concept base. opinion

14. Metadata Strategy Technical approval of surveys: • The department responsible for the survey: • updates the methodological document and/or the questionnaire(s) with the proposed changes or justifies its rejection, • submit the new version of the methodological document and questionnaire(s) for approval by the Board. • The Metadata Unit prepares a memo, on the basis of all the opinions of the different units and respective answers, to send to the Board, proposing their approval or rejection. • The Board then approves or rejects the survey. • Metadata Unit records the questionnaire(s) in the data collection instruments database and publish the methodological documentation the Intranet and in the Official Statistics website.

15. Integrated Statistical Metadata System

16. To support the wholelife cycleof surveys; To act as acentral repositoryfor statistical metadata serving as a source for other databases that support: design, production, dissemination of statistics and management; To establishterminologyfor statistical metadata; To constitute aninstrument for statistical harmonisation and coordinationof the National Statistical System, standardising the documentation of surveys, among other elements; To implement ahomogeneous environmentfor its technological infrastructure. Integrated Statistical Metadata System The main purposes of the Integrated Statistical Metadata System are:

47. Organizational and workplace culture issues Training and knowledge management III. Classifications subsystem • The main international, EU and national classifications systems used in statistics, the classifications comprising them and the relationships between them; • The approval process for classifications at different levels and harmonisation in the use of classifications in the NSS; • Improving competences in the use of the classification subsystem.

48. Organizational and workplace culture issues Training and knowledge management IV. Variables subsystem • Recognition and designation of entities making up the conceptual model; • The rules and principles in the name, standardisation and harmonisation of variables; • How this subsystem relates to other subsystems in the integrated metadata system and other outside subsystems, such as the Dissemination Database and WebInq (electronic data collection); • Use of the consultation applications and the survey manager (SM) profile of the management application; • Defining indicators to be disseminated on the Official Statistics website.

49. Organizational and workplace culture issues Training and knowledge management V. Methodological Documentation (2009) • The Statistical Council-approvedmethodological document format for documenting the National Statistical System’s surveys; • Use of the consultation applications and the survey manager profile of the management application.

50. Lessons learned • Involvement of the institution's top management, fundamental Creation of documentation with formal and standardised procedures. • Development of prototype systems before final implementation, fundamental To test the system’s design and to detect the strong and the weak points.
