  1. Microdata Information System MISSYMetadata for scientific research ESRA Conference, Lausanne 2011 Jeanette Bohr German Microdata Lab (GML) GESIS – Leibniz Institute for the Social Sciences, Mannheim

  2. Overview Service for official microdata MISSY - Metadata for scientific research Structure and application Preparation process Outlook

  3. Service for official microdata Increasing accessibility of individual data from official statistics for scientific research (Scientific Use Files) Scientific service for the use of SUFs is required German Microdata Lab (GML): offers comprehensive scientific services for the SUFs with focus on the German Microcensus* * annual population sample containing structural population and labour market data for 1 percent of all households in Germany

  4. MISSY - Metadata for scientific research MISSY is an online information system that provides metadata for official microdata in a structured design Facilitates professional and efficient use of official microdata for the social sciences Provides comprehensive and systematically integrated documentation At present MISSY contains detailed metadata for all available Microcensus Scientific Use Files (1973- 2008)

  5. Content Detailed information on variable level Comparability of variables over time Study descriptions and collection materials Concepts, classifications and definitions Setups and program routines (“microdata tools”) Literature database

  6. Structure Links between related content (e.g. from variable information level to related documents) Multiple pathways to relevant information: Lists of variables Thematic classifications Variable-Time-Matrix

  7. Raw Data xml (previous year) Scientific use files(SPSS, Stata, SAS) Setups (SPSS, Stata, SAS) xml (updated) xml (statistics) xml (matched) MISSY Web: Variable List Thematic Classification Variable-Time-Matrix Variable Information Print Version (PDF): Data Handbook Variable-& Valuelabels Thematic List xml (Editor) RDBMS DDI 3 Editor additional Metadata Preparation Process +

  8. Outlook Documentation of European microdata Multilingual information (e.g. for question texts) Information on country level (e.g. anonymisation) Further use of metadata in other systems Open Source Software
