DDI metadata standard
The Data Documentation Initiative (DDI) is an international metadata standard designed to describe socioeconomic surveys, censuses, and other microdata collection activities. The DDI standard is developed and maintained by the DDI Alliance, and the IHSN is an active partner in its development. Based on feedback from agencies in low- and middle-income countries who are using DDI-based IHSN tools, and from regional and international agencies such as the World Bank, the IHSN requested an upgrade of the DDI specification, which led to the release of version 2.5 of the DDI Codebook standard. The IHSN also works with the DDI Alliance on the certification of the DDI Codebook as an ISO standard. In addition, the IHSN commissioned the production of a paper describing various metadata standards relevant for microdata management.
