DDI Implementation Projects at SSJDA: Ongoing Projects and a Future Task

Social Science Japan Data Archive (SSJDA) has developed DDI implementation projects. We present two ongoing projects and a future task in SSJDA. The first implementation project is the Nesstar system operation since 2012. Some datasets which are provided from SSJDA are available in the Nesstar system and the number of access and users are increasing. Since mutual link with SSJDA's website is also started, cooperation between services is working more effectively. The second project is development of the software Easy DDI Organizer (EDO). EDO is an open source tool for editing and managing a metadata along with data lifecycle. Our future task is to provide users with tools to encourage users to understand and use social research. Panel surveys usually have complex structures that impede analysis. At the same time, I would like to integrate these multiple projects and improve the process of data archiving work. Discussion of these projects and future issues.
