  1. Metadata Management at GESIS-ZA Reiner Mauer GESIS – Data Archive and Data Analysis CESSDA-Expert Seminar Odense, September 11th 2008

  2. Metadata Management: Requirements • Support of common metadata elements • Interoperable with existing systems • Different user roles (management of access/edit rights) • Quick and easy update of metadata for end-users • Support for parallel content in different languages • Long-term preservation

  3. Metadata Management: simplified overview schema Creation / Administration Presentation / Retrieval DBKEdit metadata on study level: “study descriptions” + internal administrative metadata Data processing (cleaning, standardizing, harmonizing, integrating, cumulating) Data holdings catalogue (DBKSearch) ZACAT (Nesstar) DDI/XML SPSS Dataset Documentation Manager (DSDM) edit or create variable documentation ZA CodebookExplorer XML (DDI) DDI/XML migration long term preservation OSIRIS codebook

  4. Metadata Management: Metadata on Study Level DBKEdit 1.2 • Web based system with backend database (MySQL) • External and internal (administrative) metadata • DDI compliant structure of standard ZA study description • User Roles for internal and external metadata fields • Parallel English/German content • Export to DDI 2.0 • Control publication options for related materials (questionnaires, reports, …) DBKSearch 1.2 (Data Holdings Catalogue) • Web based search in up to date backend database

  5. Metadata Management: Study Level, DBKEdit

  6. Metadata Management: Metadata on Variable Level DSDM 2.5 (Dataset Documentation Manager) • Stand-alone application with backend database • DDI compliant structure of metadata • English/German interface • Parallel English/original language content (unicode) • Import SPSS and/ or XML metadata • Export DDI 2.0 metadata or CodebookExplorer database with integration of study level metadata ZACAT (NESSTAR), CodebookExplorer 3.3 • Web based or offline search/browse metadata

  7. Metadata Management: Metadata on Variable Level DSDM 2.5 Special Functions • Input and edit question and answer texts, interviewer instructions, forward/backward filters, subquestions (item batteries), archival notes, variable groups • Documentation of comparative datasets by definition of specifics (regional or temporal deviations) • Documentation of original questionnaire languages • Re-use question and answer texts from existing studies • Export Nesstar specific DDI for publication • Export long-term preservation DDI with complete structure • CodebookExplorer Database Wizard

  8. Metadata Management: DSDM 2.5, Dataset Catalogue

  9. Metadata Management: DSDM 2.5, Question Catalogue

  10. Metadata Management: DSDM Special Nesstar Export Functions • Build embedded links to related documents published via data holdings catalogue • Creation of variable groups • Selection of CodebookExplorer Database to include links to comparable variables (over time or space)  supports ZACAT Nesstar Extension for: • Trend comparison • Country/Language comparison • Show Card pictures

  11. Metadata Management: Nesstar Extension for Comparison ZACAT: Identification of Trends Example: European Value Study 1999/2000 Comparison with similar questions from 1. and 2. wave

  12. Metadata Management: Nesstar Extension for Comparison ZACAT: Comparison of language versions Example: European Value Study 1999/2000 (33 Countries, 28 Languages, 39 Datasets)

  13. Metadata Management: Nesstar Extension for Comparison ZACAT: Inclusion of Show Card Pictures Example: European Value Study 1999/2000

  14. Metadata Management: ZA CodebookExplorer ZA CodebookExplorer 3.4: • original language and show card support • browse studies or trends (continuity guides etc.) • user can define own view on collections of studies • search in study or variable descriptions • simple analysis like frequencies or crosstabs • show questionnaires • access SPSS datasets

  15. Metadata Management: ZA CodebookExplorer ZA CodebookExplorer 3.4: • original language and show card support • browse studies or trends (continuity guides etc.) • user can define own view on collections of studies • search in study or variable descriptions • simple analysis like frequencies or crosstabs • show questionnaires • access SPSS datasets

  16. Metadata Management: Future Developments • DDI 3.0 Compatibility • Advanced Reporting Facilities • Integration of workflows and tools  integration of DSDM, DBKEdit, CBE reporting plus functionality to replace SPSS for metadata/data procession (implementation depends on availability of funding) Thank you!
