The IoS-OP Data Catalog summarizes the specifications of data items required for practical data utilization.
It plays an important role not only in selecting applications that use the data, but also in ensuring data quality by aligning with the intended use.
IoS-OP continues to expand and update these data catalogs on an ongoing basis and makes them available as needed.
