MISSY - Metadata for scientific research
Structure and application
Preparation process
Outlook
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
MISSY - Metadata for scientific researchMISSY 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)
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
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
xml (previous year)
xml (updated) Setups (SPSS, Stata, SAS)
Raw Data
xml (statistics)xml (matched)
