The purpose of Korean Diaspora Digital Archive System (KoDDAS) is to provide a digital data management infrastructure for aggregating, organizing, and disseminating Korean Diaspora data for research communities as well as the general public. In that regard, KoDDAS extends the conventional archival functions of collection and preservation to focus on information dissemination and data reuse. To promote data reuse, KoDDAS will implement an integrated online database system that contains not only the raw data, but also the contextual and structural metadata that can facilitate the understanding and analysis of Korean Diaspora data.
