What is DDI?

For developers, adopting DDI facilitates smoother integration, interoperability, and automation.

How DDI Helps Developers

  • Facilitates Integration: DDI's standardized metadata format ensures data can be integrated across different data repositories and discovery platforms.
  • Supports Interoperability: DDI ensures data are compatible with other systems through common formats.  
  • Automates Data Processing: Structured metadata enables automation in data pipelines.

How to Get Started

  1. Choose the Relevant DDI Schema -- Learn about DDI products.
  2. Use Tools -- Leverage DDI tools to import, integrate, and export DDI-compliant metadata to your data system or repository.
  3. Integrate with Existing Systems -- Implement DDI metadata in repositories or research applications.
