    • General Information About Missy• Missy (Microdata Information System)• Provides detailed information about individual datasets• Contains metadata of microdata relevant for the social sciences• Facilitates data usage for research• Currently consists of microcensus survey • Largest household survey in Europe • statistics about • general population in Germany • situation about employment market (occupation, professional education, income, legal insurance, …) 5
    • General Information About Missy• May be split in two parts • Missy Web (end-user front-end part) • Missy Editor for documentation (back-end part)• Consists of approx. 500 Variables & Questions per year• Captures 25 years, since 1973 6
    • Missy 3• That’s what it’s all about! The “next generation Missy”• Integration of further surveys, e.g. EU-SILC, EU-LFS, …• Implementation of Missy Editor as a Web-Application 7
    • Use-Cases in Missy• General Information about survey microcensus• Variables by thematic classification and year• List of variables by year• List of generated variables by year• Show details of a variable with statistics• Variable-Time Matrix • List of variables by thematic classification and year (selectable)• Questionnaire Catalogue• In future: browse by survey and country! 8

    • Group (study and variable information) --> variables in this group are comparable --> inheritlabel = variable age --> overwrite variable information label = age + easy to understand - Implementation - changes --> reorganize groups 46
