This report presents the metadata information infrastructure project funded by the Ministry of Internal Affairs and Communications, Japan. The goal of this project is to build a metadata schema registry to support sharing of metadata schemas on the Internet and promote reuse of metadata schemas and metadata interoperability. The registry is designed based on the Singapore Framework. Partners in this project include several major memory organizations, research institutions, and private sector entities in Japan. This project has collected several metadata schemas from the partners and converted them into the formal project schema based on RDF. This report first presents the background and goal of the project, and then the requirements and design of the registry system named Meta-Bridge.
