Data Documentation Initiative (DDI)

The Data Documentation Initiative (DDI) is a standard for documenting data from social science research. It helps researchers and data users understand data sets by providing detailed information about the data's content, structure, collection methods, and context. This ensures that data can be effectively shared, reused, and analyzed by others. Think of DDI as a thorough guide or instruction manual that accompanies data, making it easier to interpret and use for research purposes, ultimately enhancing the quality and transparency of social science data analysis.
