DDI Recognized as an ISO Standard
I’m pleased to announce that the DDI Alliance suite of products is now codified by an ISO standard. On 6 March 2026, the International Organization for Standardization released ISO/PAS 25955 , formally recognizing the Data Documentation Initiative (DDI) within the ISO standards framework. This milestone reflects many years of collaborative work by the international DDI community to support consistent documentation and interoperability of research and statistical data. The IASSIST community has played an especially important role in the development, implementation, and advancement of DDI metadata standards from their earliest stages.
