Museum information in Japan is maintained distributedly and nonuniformly. This leads to difficulty in crossover searching for museum information. The LODAC (Linked Open Data for ACademia) project is building a prototype system (LODAC-Museum) to aggregate information across multiple sources. We identify and associate artists and works from different museum collections to provide integrated views for them. The key technology is Linked Data. All the aggregated data is transformed to the standard metadata schema and linked to each other via generated ID resources.
