DDI

In the efforts for the internationalization of data archive and the projects in the Joint Usage / Research Center, the CSRDA has been active promoting the implementation of the Data Documentation Initiative (DDI), one of the major international metadata standards for social science research.

The current implementation consists of the two principal projects. The first is the operation of Nesstar system, the DDI-based metadata publishing and online analysis system widely used in overseas. The second is the Easy DDI Organizer (EDO), a software development project for DDI-based metadata management and survey planning.
