  1. A. Götzfried Head of Unit B6 Eurostat Integration of the Eurostat and ESS Metadata Systems

  2. Outline The Eurostat Metadata-Handler and two of its main components Euro SDMX Registry National Reference Metadata Editor (National RME) The standard structures for metadata reporting Euro SDMX Metadata Structure (ESMS) ESS Standard for Quality Reports structure (ESQRS) The Generic Statistical Business Process Model (GSBPM) Impacts on the statistical business processes 2

  3. The Eurostat Metadata-Handler is the backbone of a metadata-driven harmonised statistical business process at Eurostat and in the European Statistical System; provides one central interface for accessing different types of metadata by Eurostat staff or by ESS members; provides services to other IT applications within the ESS; is the primary source for different types of harmonised metadata to be used within Eurostat and the ESS. 3

  5. The Euro SDMX Registry as part of the Eurostat-MH The Euro SDMX Registry currently contains : • the Eurostat and ECB Data Structure Definitions in use for GESMES-based data transmission; • the code lists currently used in the different GESMES-based Data Structure Definitions; • the list of data and metadata flows (from countries to Eurostat); • the list of statistical concepts used in the abovementioned data structure definitions; • some additional information such as provision agreements, etc. The Euro SDMX Registry will contain in the future: • the agreed SDMX data and metadata structure definitions used in different statistical domains for data and metadata exchange; • the harmonized code lists used in SDMX data structure definitions; • national data structure definitions and code lists used in the ESS countries (if uploaded by countries).

  6. The use of the Euro SDMX Registry for National Statistical Authorities The National Statistical Authorities will have access to the Euro SDMX Registry : for storing the data and metadata structure definitions they are using at national level; for storing the code lists they are using at national level; for retrieving the SDMX data and metadata structure definitions used within the ESS or beyond; for retrieving the harmonised structural metadata (code lists) used within the ESS or beyond; for retrieving information related to data and metadata flows and other standards (the concepts used, the provision agreements, etc… )

  7. The National Reference Metadata Editoras part of the Eurostat-MH The National Reference Metadata Editor : • is the component dealing with national reference metadata; • will accommodate the current ESS standards for reference metadata such as the ESMS or the upcoming ESQRS; • is addressed to the national producers of reference metadata, who will be able to compile their domain-specific metadata on-line and transmit them to Eurostat; • is the IT tool stimulating the harmonization of reference metadata within the ESS; • will be made available to the ESS later in 2010.

  9. The standard structures for Metadata reporting Progress made since 2008 : 2008: introduction of the Euro SDMX Metadata Structure (ESMS) at Eurostat and the ESS for the production and dissemination of reference metadata (Commission Recommendation 498/2009) 01/2009: release of the new version of the ESS quality reporting documents: ESS Standard for Quality Reports (ESQR) ESS Handbook for Quality Reports (EHQR)  Detailed requirements following the European Statistics Code of Practice ESS Quality and Performance Indicators (QPI’s) defined 03/09: EP/Council Regulation 223/2009  Article 12 defining the quality criteria to be reported 9

  10. The Euro SDMX Metadata Structure (ESMS) The 21 concepts and sub-concepts of the ESMS : 10

  11. The Euro SDMX Metadata Structure (ESMS) The ESMS is more oriented to the USERS of statistics: helps to understand the statistical data released does not include too detailed information on data quality uses 21 SDMX cross domain concepts now attached at upper level on Eurostat’s website 11

  12. The new ESQRS • Based on the ESQR (ESS Standard for Quality Report), a new report structure - the ESS Standard for Quality Reports Structure: ESQRS - was created for harmonising the reporting on statistical data quality within the ESS. • The ESQRS is using the main statistical data quality criteria as listed in EP/Council Regulation 223/2009 and as being part of the ESMS and details them further : • Relevance • Accuracy • Timeliness and Punctuality • Accessibility and Clarity • Comparability • Coherence • A subset of the Quality Performance Indicators (QPI’s) is covered in the new ESQRS

  13. From ESQR to ESQRS

  14. ESMS and ESQRS • ESQRS is more oriented to the PRODUCERS of statistics • to monitor the quality of the statistics produced in detail • concentrating on the main quality concepts (being also part of the ESS Statistics Regulation No 223/2009) • The information in the ESQRS is more detailed than the information on quality criteria in the ESMS but there is consistency and information common to both ESMS and ESQRS  ESQRS goes deeper than ESMS in terms of quality criteria

  15. ESMS and ESQRS

  16. The Generic Statistical Business Process Model (GSBPM)

  17. The GSBPM in Eurostat : the Eurostat CVD

  18. Impacts on the statistical business processes • The Eurostat Metadata Handler is SDMX compliant and impacts the statistical business process at Eurostat and within the ESS: • The Euro SDMX Registry will make available all SDMX harmonised artefacts (Code lists, DSD’s, MSD’s, etc.) to Eurostat and the ESS • The National RME will offer a way to harmonise the collection, structure, content and format of national reference metadata and national quality reports • Development of ESS common building blocks • Eurostat works on a standardised process metadata structure

  19. All over Good progress of the Eurostat Metadata Handler since 2008 but work has to be pursued in harmonisation and integration of the statistical business processes Implementation of the ESS metadata standards is essential to: enable a more automatic production, exchange and dissemination of metadata minimise the reporting burden for statistics producers improve availability and clarity for statistics users promote for international exchange of information reduce the costs and burden in Eurostat reinforce the reporting according to EP/Council Regulation 223/2009 The harmonisation work also considerably contributes to the improvement and integration of the statistical business processes as defined in the Commission Communication 404/2009. 19
