The purpose of this study is to construct an LOD model that connects and structures DA-based learning materials and related information. To this end, we develop a LOD dataset for the S×UKILAM learning materials archive by structuring the metadata using machine-readable RDF. The metadata are hierarchized by characteristics centering on the materials, and each resource is assigned a URI to enhance the searchability of the materials and related information. Following this, we develop a SPARQL endpoint to confirm the connection and structuring of the materials and related information. In addition, for users who are not familiar with the SPARQL language, we also develop an application that enables users to intuitively retrieve materials and related information by using metadata items. The result shows that the LOD model can connect DA-based learning materials and related information, and can be retrieved based on the structured metadata. We consider that the results of this study have contributed to the informatization of education and the promotion of the use of digital cultural heritage.
