  1. Metadata System at Croatian Bureau of StatisticsPresented by Branka Cimermanović, Research & Development Dept., Head

  2. Contents: • Current situation • Metadata model and methodology • Metadata system architecture • The team and related issues

  3. Current situation: CROMETAISIS • production of statistics • development upon the strategy Future situation:

  4. WINDOWS 2003 NETWORK (400+ workstations) MAINFRAME: IBM 9672 R31 EMC2 SYMETRICS STORAGE Windows XP, Office 2003, XP… OS/390 CICS, PLI, Universe etc. IBM IFP + ACTR

  5. Metadata and the CMF Generic Survey Business Process

  6. Metadata Model and Methodology CROMETA: • extension of Reference Model TMwith additionalconcepts and/orcharacteristics

  7. Metadata Model and Methodology (cont.) CROMETA sections: Studies and questionnaires Variables and measurements Classifications Publications Organisational structure History and version handling General metadata Processing and validation rules Access and authorization rules

  8. Metadata Model and Methodology (cont.) • Meta-metadata • Organisation level – institution, statistical division, statistical department • User group type – administrators, experts • Privileges – add, edit, delete • Variable type - alpha variable, beta variable, gamma variable, time variable • Cube availability - official, internal, private, etc. • Compatibility – compatible with Eurostat definition, not compatible with Eurostat definition, etc.

  9. CROMETA Model > 170 concepts > 230 tables

  10. System Architecture a) metadata server:

  11. System Architecture (cont.) CROMETA Metadata Server: • Crometa Metadata Notion • Crometa Metadata Storage Central • Crometa Metadata Business • Crometa Metadata Manager • Crometa Metadata Consumer Services

  12. System Architecture (cont.) b) metadata management tool: • a user- friendly interface to the central metadata repository • lots of descriptions • further development expected

  13. System Architecture (cont.) c) version management:

  14. System Architecture (cont.) Versions: • Under development • Released • Authorised • Archived • Frozen • Deleted

  15. The team Development: • Methodology development • mapping different metadata consumer’s models to Reference Model TM • collection of metadata in CBS • specifications and support for technical implementation • Technical implementation • conceptual design of metadata model • physical implementation • development of maintenance tool

  16. The team (cont.) Partners to CBS: • Sida    • SCB    • consciousTM   

  17. Summary • CBS survey business process fits to the CMF generic statistical survey business process • CROMETA contains metadata on all elements of survey business process with emphasis on the processing phase • system architecture • metadata management tool • in-house development with significant Swedish assistance • finalization delayed due to shortage of IT developers
