[MGI27-03] Metadata mapping between disciplinary and general schemas for promotion of data use by a wider community
キーワード：メタデータ、SPASE、JPCOAR、メタデータマッピング、機関リポジトリ、IUGONET
Metadata refer to data that describe data themselves or contents of the data. In the Inter-university Upper atmosphere Global Observation NETwork (IUGONET) project, we have been creating metadata for ground observation data in space physics and populating them into the database since 2009 (http://www.iugonet.org/). The number of metadata stored in the database has reached approximately 1200. These metadata followed the IUGONET metadata schema (or data model) version 2.4.0.1, which is an extension of the SPASE (Space Physics Archive Search and Extract) metadata schema version 2.4.0.
The IUGONET metadata database is very useful for researchers to search for data that they need and to obtain detailed information about data, but the metadata search is available only through the IUGONET page or NASA Heliophysics Data Portal. To promote data usage by a wider research community or the general public, it is needed to convert the metadata database from the SPASE schema to more general one so that the metadata can be ingested into other metadata databases. For that purpose, we developed a mapping table from SPASE to the JPCOAR (Japan Consortium for Open Access Repository) schema, which has been widely used for scholarly communication and data publication in Japan. Based on the mapping table, we converted part of our metadata, which describe data created in Nagoya University, to those in the JPCOAR schema. The converted metadata were registered in the institutional repository of Nagoya University (https://nagoya.repo.nii.ac.jp/). These metadata are consequently harvested by Institutional Repositories DataBase (https://irdb.nii.ac.jp/), Data Catalog Cross-Search System (https://search.ckan.jp/), Google Dataset Search (https://datasetsearch.research.google.com/), and other metadata repositories. We plan to do the same action for the other IUGONET metadata. This will significantly enhance findability and accessibility of the IUGONET metadata and their describing data.
