| Fields | Space Physics | Environmental Sciences | Social Sciences | Materials Science | Humanities |
| Characteristics | Mostly numerical data | Image data, numerical data, etc.. | Survey data | Measurement data, calculation data, Material Informatics data, software | Image data, bibliographic data |
| Data holder (Representative) | The person(s) who is/are acquired the data | The funder(s) | The data provider | Institution of the data holder (with exception) | uncertain |
| Request for users | None | # Request for user name and purpose of use for searching metadata # Primary data are negotiated on an individual basis | # Only available by the researchers who belongs in the social sciences discipline # Submission of a research proposal is mandatory # Submit usage reports every year/Inclusion in the acknowledgments for using the data | Provide a provenance information of the data as well as literature citations | # The metadata should be CC0 # The conditions of use of the data should be clearly stated by data holder |
| Penal regulations | There are no publishing constraints from a scientific point of view | Under consideration | If the data is passed on to a third party without permission, the use of the data may be suspended | None | Considering the use of rightsstatements in case of publishing data |
| Rights protection | No rights protection is provided for the data to be published | There are two levels of access restrictions on data in the repository, depending on the contents | One-year and indefinite licenses are available according to the wishes of the data holder | Data marked as private will have restricted access | Non-public data will be considered for protection on an individual basis by contract. Among the public data, those with copyright properties will be subject to government of Japan standard terms of use and CC licenses |
| Issues | # There are few explanation for national security related data (especially the description of disclosure period) | # There are no institution to consult about research data rights in Japan | # In addition to an organization that supports data management, data management personnel and personnel who can handle the technical aspects of metadata are needed # The criteria for determining sensitive data change over time, so it cannot provide past data as it is | # A point of contact is needed to receive inquiries about published data | # Licensing standards for publishing non-copyrighted or obscure data # How to develop a culture of data protection, who will bear the cost, and how to spread it The future discussion points are whether or not to do so |
| Aspiration related to conditions of use | Development of data utilization laws | Enhancement of the university’s intellectual property department function |
