Tools for microdata cataloguing
The IHSN recommends the adoption of the Data Documentation Initiative (DDI) metadata standard for the documentation, cataloguing and dissemination of survey microdata.
The IHSN and the World Bank have developed a free, open-source, DDI-compliant application for the cataloging, and dissemination of microdata. This application complements the IHSN specialized DDI metadata editor.
To access the cataloging software application (National Data Archive or NADA), see our Software section.
