Cultural Property Information with Linked Data: Seminar Held by the Department of Art Research, Archives and Information Systems

Scene of the seminar

 The 3rd seminar was held by the Department of Art Research, Archives and Information Systems on June 25th, 2019. Taiki MISHIMA (Department of Art Research, Archives and Information Systems) gave a presentation titled “Aggregation of regional cultural heritage information based on Linked Data,” and Mr. Ryoji MURATA (Tokyo National Museum) was invited as a commentator.
 Linked Data is a way to realize the Semantic Web. By tracing the links between structured Linked Data, relevant information based on individual needs can be gained. Linking open data to external resources based on Linked Data will improve data discoverability and its potential uses. In recent years, the attention is being paid to the utilization of regional cultural heritage because of the amendment made to the Act on Protection of Cultural Properties, and MISHIMA has focused on the utilization of regional cultural heritage “information” in Japan and has proposed the metadata schema and pointed out the issues involved when aggregating and publishing this information as Linked Data.
 As a result of an analysis of the information regarding a designated cultural heritage, published by local public bodies in Tokyo, commonalities and differences were clarified in terms of description items such as name, category, and location of cultural properties, the vocabularies used in the description items, and the description formats. In order to aggregate this information based on Linked Data, a metadata schema was created wherein information with unified vocabulary and description format prevailed along with the original information. One of the issues be highlighted was the relationships between vocabularies, such as “tangible cultural property” and “buildings,” which are specific to cultural property categories as data, and which would need the model for constructing the thesaurus.
 At the seminar, participants exchanged opinions on a broad range of topics, such as how cultural heritage information has been created, shared, and published on the basis of their experiences in dealing with cultural heritage.
