- The document discusses connecting museums through linked open data (LOD). It outlines the LODAC Museum project which aims to aggregate and associate over 1.4 billion collection objects from over 1,000 Japanese museums and cultural organizations. - The project gathers data from various sources, standardizes the data, integrates it by identifying and associating the same data points, and publishes the integrated museum data as LOD. - By connecting museum data to other types of data through LOD, it can provide new value like connecting works to local information, events, and enabling user-generated contributions about cultural collections.
