Study Support and Integration of Cultural Information Resources with Linked Data
A museum collection search system called Linked Open Data for Academia (LODAC) Museum has been developed that uses Linked Data. The LODAC Museum identifies and associates artists, artworks, and museum information from some different museums to provide integrated data that are published as Linked Data with the SPARQL endpoint.

Up until now, lots of Japanese museums have been built Online DB and Digitized collection.
Each museum has developed separate collection management system with original metadata.
It is difficult to retrieve relevant information by searching multiple museum information.

Summary
• Organizing We tried to integrating distributed information as Linked Data. In consequence, approximately 11 million information available for common platform.
• Publishing We published an RDF data on a LODAC Museum website. These are everybody can use for free!
• UsingCurrently, the two applications use LODAC Museum’s Data. We are more consider how to use these resources. (We have a plan to use for the purpose of study)
