Metadata Management at GESIS-ZA
Reiner MauerGESIS – Data Archive and Data Analysis
CESSDA-Expert Seminar Odense, September 11th 2008
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
Metadata Management: simplified overview schema

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
Metadata Management: Study Level, DBKEdit
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
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
Metadata Management: DSDM 2.5, Dataset Catalogue
Metadata Management: DSDM 2.5, Question Catalogue
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
Metadata Management: Nesstar Extension for Comparison
ZACAT: Identification of TrendsExample: European Value Study 1999/2000
Comparison with similar questions from 1. and 2. wave
Metadata Management: Nesstar Extension for Comparison
ZACAT: Comparison of language versionsExample: European Value Study 1999/2000
(33 Countries, 28 Languages, 39 Datasets)

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

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)
