This paper briefly describes the basic concepts and current status of portal sites that National Institute of Informatics (NII) is involved in the design and operation for the Digital Silk Roads (DSR) Project. These portal sites aim at disseminating and sharing cultural heritage information related to Silk Roads. This paper introduces two portal sites, namely Toyo Bunko Portal, and Advanced Scientific Portal for International Cooperation on Digital Silk Roads (ASPICO-DSR). This paper also addresses other related sites and programs, namely Cultural Heritage Online and ECAI and concludes with a future plan.
