About Statistics Sweden Statistics Sweden is a central government authority for official statistics and other government statistics and in this capacity also responsible for coordinating and supporting the Swedish system for official statistics. Statistics Sweden’s mission –In order to supply customers with good quality statistics to be used as the basis for decision-making, debate and research, Statistics Sweden will: –develop, produce and communicate statistics, actively contribute to statistical cooperation on an international level and coordinate and support the Swedish system for official statistics.

Organisation

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

The Lotta project

Process maintenance and process development

The MetaPlus 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

Metadata management The Research and Development department is responsible for maintaining and developing metadata systems and templates Due to the decentralised organisation groups and networks are of great importance The publishing department is responsible for presenting metadata and is also responsible for the statistical databases (SSD) and the metadata belonging to it

Overall objective (main goals) Document metadata once, metadata should be collected when “made”, reuse Standardised metadata should be used when it is possible One metadata repository for micro and macro data and other processes

Lessons learned (future challenges) Involve users at an early stage in development. Makes them feeling a part of the development Inform a lot Make some sort of prototype at an early stage, it is very difficult and abstract for users to describe use cases for a system with this complexity How and what process metadata are we going to collect?

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

Types of documentation and tools, inter-relationship

Description of the statistics According to the Swedish Statistics Act they must be produced for all statistics products. –Purpose: provide brief information on the quality of the statistics and other basic facts. The descriptions serve an important function as a quality declaration for the published statistics. Free text format, main chapter’s: –General information –Quality declaration

Statistical Metadata in the Statistical Cycle The Lotta-project –The work on describing the production process is ongoing at the moment. The SCBDOK template covers the whole production process MetaPlus primarily describes the content in the final observation registers –Can be used to describe any data matrix at any other production stage as well

Systems and Design issues The various parts of the Swedish metadata system are not fully integrated. Some parts (SCBDOK, Description of the Statistics) are simply templates to be filled out in Microsoft Word. –Presented on the web –MetaPlus, traditional client/server system, using a relational database as its core and a "fat client" application for data entry and maintenance, or web browser based "thin client" for presentation. –Metadata for aggregate data are documented in a separate system: SSD. The development tools used are all from Microsoft: SQL Server and Visual Basic.NET. The tools available to users for creating documentations are the Word templates, the MetaPlus application and the SSD application. Development of the entire Swedish Metadata system has been carried out in-house, taking international standards (ISO11179, Neuchâtel) into consideration. Revision of IT architecture –probably adopting the SOA principles

Organizational and cultural issues Subject matter statisticians –Documenting –Responsible for the content The KMI group The metadata group The documentation network –Training issues The classification network

Summing up Content org –Standardisation and harmonisation is very time consuming –Se principles for content –Work on harmonisation guidelines as early as possible Experiences –Migration of content is difficult –Make a simple prototype at an early stage Future –One repository – one tool –Metadata and process data in the production process
