MetaPlus Klas Blomqvist Statistics Sweden Research and Development – Central Methods

Agenda The VHS-project –Background MetaPlus –The concepts, the product KMI-group –Support and management for classifications, metadata and content harmonisation The Lotta project, process reengineering at Statistics Sweden –A more effective production process –MetaPlus, future development MetaPlus and the production process

Why do we need metadata?

Metadata at Statistics Sweden SCBDOK –Word template, standardised structure free text description MetaPlus (Metadok) –Formalized metadata, coded information KDB, the classification database –Statistical standards and classifications Other documentation –Description of the statistics – the quality declaration –Product database –Private production documentation

The VHS-project The VHS-project started 2004 –Compilation of requirements: Metadok, new requirements Systems design from 2005 –Use cases, modeling System development 2006 –Application, data base Production 2007 –From January 2

MetaPlus Replace Metadok Scope: –Documentation tool with improved quality –Better overview over variables and data –Tool for standardisation and harmonisation –Possibilities for reuse and coordinated use –Consecutive documentation Requirement: –That the documented material in Metadok can be migrated

Information User groups The Metadata group (reference group) The methods council The IT council The register council The board of directors The scientific council Seminars

The plus with MetaPlus Support for the production –Cooperation with other metadata systems, Archiving, the Personal Data Act, connection to data User support –Search the microdata Improved quality –Contents, accessibility and comparability More cost-effective –Increased use of collected data Reduced respondent burden –No new collection if data already exists

Easier to document Starting point in already existing metadata –Classifications and standards –Documentations made by others –Search the metadata repository Document once - reuse Input data in the form of tables –Document the table at once instead of one cell at a time Consecutive documentation Effects: –Higher metadata quality –Automatic harmonisation

Using MetaPlus New requests (commissions), new surveys –Examine if the issue can be solved with already existing data. Information for facilitating coordinated use and harmonisation Search for variables –Look at value domains Find information on populations –Shows possibilities for matching data –Highlights differences in data materials

The KMI-group Research and Development department, all units represented –Management, Central Methodology, Register coordination and microdata and Central IT units Responsibilities –Classifications –Metadata –Content harmonisation MetaPlus support –Migration, training, helpdesk

The Lotta project Standardised production and tools –Process orientation –Customer focus –Efficiency –Standardisation –Quality control New organisation after summer –Internal review during summer
