Methodology and processing
Data-access
– Data Files Description
(Meta) data 1999—GESIS ZACAT
• Comparative questions (master questionnaire)
with 1981 and 1990
• Original question wordings for all languages:
question texts, answer categories, and show cards
of the questionnaires
• Explanatory notes concerning differences between
national and master questionnaire, difficulties
arising from translation, and additional questions
used in the national questionnaires were added.

Harmonising different waves
• In 2006 a harmonised data set was released after
(post hoc) harmonisation of all Value Surveys
since 1981 (ASEP/JDS, EVS-Tilburg, GESIS)
• Goals:
– Make all Value Surveys available on line
– Facilitate simple analyses
– Disseminate all documentation
• Web sites where data are available:
– EVS www.europeanvaluesstudy.eu
– ASEP/JDS www.jdsurvey.net
– WVS (Enter from WVS )
• ALSO HARMONISING META DATA
Meta data 2008
• Improved presentation on ZACAT
– Including more notes from the translation
process
• DatapluS: Repositories for Enhanced
Survey Publications
DatapluS
Funded by Surf Foundation
Create 2 subject repositories with enriched publications
• Besides European Values Study (EVS), also Dutch
Parliamentary Election Study
• Enriched with:
– Syntax codes of constructs, concepts
– Links to (meta) data (at the variable level)—persistent
identifier issue
Work Packages
• 1,2: INPUT: Enhanced Publications (EVS, DPES)
• 3: A Sustainable Library Infrastructure for
Enhanced Publications: LIS (Tilburg University)
Library Twente (presentation Thomas Place)
• 4: DDI 3.0 Enhanced Publication Editor:
CentERdata (Tilburg University); presentation
Bart van Nieuwburg
• 5: Linking to (Meta) Data Stored in Data Archives
(GESIS, DANS)
Deliverables
• 2 subject repositories with enriched
publications
• Enhanced Publication Editor
• Infrastructure compatible with existing
repository systems
Future issues
Make more meta data available in a more
coordinated way
 Use version control of (meta)data—also cross
linking data releases
 Further integration of publications and data
 Integration of data from different sources (macro
indicators)

