Improvement of metadata interoperability for promoting distribution and utilization of Japanese digital cultural resources

Abstract

The National Diet Library, Japan (NDL) has contributed to promoting utilization of Japanese digital cultural resources by operating Japan Search, the national metadata platform of Japanese digital content in various fields. While Japan Search accepts metadata regardless of schema to minimize the workload of data providers and enable rapid expansion of searchable databases, it is necessary to improve metadata interoperability to enable efficient utilization of resources. This presentation covers practices to improve metadata interoperability such as an initiative in the community providing metadata to Japan Search and improvement of RDF provided by Japan Search.
