In this presentation, we introduce and discuss “Mingu Web,” an application for collecting information on historical and cultural materials such as mingu. To solve the problem of preservation, succession, and utilization of regional mingu materials, the Academic Repository Network (Re*poN) is developing the “Mingu Web” application as a platform for collecting and sharing information on mingu materials. This application allows anyone to share and browse information on catalogs, bibliographies, and events, including exhibitions. The information to be shared can be incomplete; sharing only images or incomplete catalog information is acceptable. By lowering the hurdles to information sharing in this way, we aim to make more mingu materials discoverable and utilizable. We also envision that the application will contribute to the formation of a community for the collection and utilization of information on mingu by linking with existing public databases and by being used to collect information on materials and exhibitions at museums and other institutions.
