THE BNSI EXPERIENCE IN METADATA COLLECTION AND ORGANIZATION

1. THE BNSI EXPERIENCE IN METADATA COLLECTION AND ORGANIZATION Joint UNECE/Eurostat/OECD Work Session on Statistical Metadata (METIS) 3-5 April 2006, Geneva Joint UNECE/Eurostat/OECD Work session on Statistical Metadata (METIS)

2. Paper contents • Essence and goal of ISIS and principles of development component by component • Standards for the metadata description in information systems • The place of the developing components in the ISIS architecture • Organizationofmetadatacollection – realization through the statistical information systems • Future tasks Joint UNECE/Eurostat/OECD Work session on Statistical Metadata (METIS)

3. Specific topics in the experience • No possibility to develop components in the best way - Necessity the developing components to be integrated and every new component to be integrated to the existing; • Component by component development of the ISIS; • The Metadata components – tools for metadata collection Joint UNECE/Eurostat/OECD Work session on Statistical Metadata (METIS)

4. ISIS – brief presentation • Connected obejct oriented and process oriented ISs • Centralized DBs – common, sharing DBs with controled access • Core component – Metadata base • Metadata driven system • Architecture – Standard 51 Information Systems Architecture for National and International Statistical Offices • Infrastructural components • Functional components • Databases – Observation registers, Final observation registers, Macrodata base, Dissemination DB Joint UNECE/Eurostat/OECD Work session on Statistical Metadata (METIS)

5. Step by step development of ISIS • Guiding principles: • the ideology and architecture of ISIS defined – strict adherence working on developing separate ISIS components. • common metadata model implementation in separate ISIS components. • interfaces between information systems if possible, especially for the metadata exchange. • developed and approved internal standards. • ConsolidationoftheITenvironmentandITelementstobeachieved; • Common development tools to be used in the development of the system. • Not to destroy the “statistical production” process Joint UNECE/Eurostat/OECD Work session on Statistical Metadata (METIS)

6. Developing systems – why these IS • IS “Statistical classifications” – service provided for the other components – development, maintenance, relations between, usage of the statistical classifications; • IS “Register of the statistical units” – administrative and statistical units, statistical surveys population; • IS “Planning and design of statistical survey” – application SW tool for MD collection – life cycle – survey description • Electronic Metadata Vocabulary – terms & definitions and their maintenance • IS “Demography” – integration - DWH Joint UNECE/Eurostat/OECD Work session on Statistical Metadata (METIS)

7. MetaNet Reference model – how it is used - common information objects and their use Requirements for information system integration – internal standard; Information Services between information systems – internal standard Standard used Joint UNECE/Eurostat/OECD Work session on Statistical Metadata (METIS)

9. How the ISs are related Joint UNECE/Eurostat/OECD Work session on Statistical Metadata (METIS)

10. Organization of the MD collection • IS “Planning and design of statistical survey”, IS “Statistical classifications”, EMDV – application SW tools for MD collection – standard survey description; • Co-ordination council – Vice-President, Directors, defined rules – internal standards approval; • Working groups – the best experts in the statistical office • Programme for survey description – implementation of the systems Joint UNECE/Eurostat/OECD Work session on Statistical Metadata (METIS)

11. Future work • National PHARE 2004 Programme – TS for development of ISIS – detailed plan with more technical requirements for ISIS realization • TS for development of the functional component “Data collection and editing” – including Micro DB building up (Observation and Final observation registers) • Data from administrative sources • Data dissemination DB and functional component Joint UNECE/Eurostat/OECD Work session on Statistical Metadata (METIS)
