Designing an Ontology for the Data Documentation
                    Initiative
Problem
• Establish the Data Documentation Initiative (DDI) as a de facto standard for describing data from the social and
  behavioral sciences
• DDI should reach a broader audience

Purpose
•   Publish data and metadata in form of RDF
•   Link data and metadata in the web --> DDI instances participate in the LOD cloud
•   Plethora of tools to interoperate with DDI instances can be used
•   Identify use cases
•   Build ontology of the most relevant DDI elements

Research Questions and Methodology




Use Cases
• Semantic queries                                                • OWL queries
    • What kind of problems can be solved?                            • Terminological OWL queries (Global consistency, class
    • On multiple distributed and merged DDI instances                  consistency, subsumption testing, classifying the
    • Using DDI domain concepts without knowledge of                    ontology, class equivalence, class disjointness)
      DDI XML Schemas‘ structures                                     • Assertional OWL queries (Instance check, class
• Publish DDI data and metadata in form of RDF                          extension, property check, property extension)
    • DDI instances can be processed by RDF tools without         • Consistency check of DDI 3 data model
      supporting the DDI data format                              • Facilitation of study comparability
• Link DDI data and metadata with different data                  • Enabling study classification
  sources of the LOD cloud                                        • Meaning of references in the DDI data model will
• Ontologies are more expressive than XML Schemas                   be formalized
• Integration of other ontologies                                 • Storage of qualitative data
    • Reasoner can use additional semantic information for
      deductions

Designing an Ontology for the Data Documentation Initiative Problem • Establish the Data Documentation Initiative (DDI) as a de facto standard for describing data from the social and behavioral sciences • DDI should reach a broader audience Purpose • Publish data and metadata in form of RDF • Link data and metadata in the web --> DDI instances participate in the LOD cloud • Plethora of tools to interoperate with DDI instances can be used • Identify use cases • Build ontology of the most relevant DDI elements Research Questions and Methodology Use Cases • Semantic queries • OWL queries • What kind of problems can be solved? • Terminological OWL queries (Global consistency, class • On multiple distributed and merged DDI instances consistency, subsumption testing, classifying the • Using DDI domain concepts without knowledge of ontology, class equivalence, class disjointness) DDI XML Schemas‘ structures • Assertional OWL queries (Instance check, class • Publish DDI data and metadata in form of RDF extension, property check, property extension) • DDI instances can be processed by RDF tools without • Consistency check of DDI 3 data model supporting the DDI data format • Facilitation of study comparability • Link DDI data and metadata with different data • Enabling study classification sources of the LOD cloud • Meaning of references in the DDI data model will • Ontologies are more expressive than XML Schemas be formalized • Integration of other ontologies • Storage of qualitative data • Reasoner can use additional semantic information for deductions Thomas Bosch, Andias Wira-Alam and Brigitte Mathiak {Thomas.Bosch, Andias.Wira-Alam, Brigitte.Mathiak}@gesis.org GESIS - Leibniz Institute for the Social Sciences, Square B2, 1, 68159 Mannheim, Germany
