Abstract
The National Institutes for the Humanities (NIHU) have been developing an integrated retrieval system (nihuINT) using existing research databases and the sharing of resources for application purposes since 2005. However, 10 years have elapsed since nihuINT was constructed, and some problems have been identified. To solve these problems, we began to construct a database as a prototype for a new nihuINT. We focused on two databases for our experiment. One deals with “rare Japanese classical books,” and the other deals with “Shoen” (a field or manor in Medieval Japan). We took these databases and rebuilt them as RDF (Resource Description Framework)Store/RDF databases.
