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: 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: 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 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 Trends

Example: European Value Study 1999/2000

Comparison with similar questions from 1. and 2. wave

Metadata Management: Nesstar Extension for Comparison

ZACAT: Comparison of language versions

Example: 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)
