Intended Output

Documents on following possible areas:

• Interoperability
  • Application of DDI together with other specification(s)
    • Cross-specification and cross-discipline use cases
    • Discovery across domains
• Integration of other specifications in DDI on binding level and/or model level
• Relationship between controlled vocabularies (i.e. glossaries) and ontology-based approaches
• Provenance as part of methodology
• DDI 4 Production Framework
  • Changes and improvement
  • Design patterns
    • Review of existing DDI work
    • Determination of additional areas where patterns can make sense
    • Relationship to general existing approaches (like GRASP - General responsibility assignment software patterns and GoF - Gang of Four)
    • How can patterns support interoperability? (see interoperability above)

• Relationship of stages of the data life cycle
• Relationship of tasks in GSBPM/GLBPM
• Relationship of aggregate data to underlying microdata
• Data description
• Review in the light of other disciplines, especially CSVW, HL7, CDISC, SDMX, and GSIM
• Review in the light of the use cases of the W3C CSVW working group
• Usage of CSVW in RDF binding (see interoperability above)
• Usage of FHIR and DDI together
• Multiple bindings in other specifications
• Pros and cons of different approaches
