This FAIRsharing record describes: 1.Since 2019, the repository has accumulated 56,308 registered users and hosted 4,096 datasets over the same period, providing open data services for 7 years. If included in the repository list, it falls under the category of "Earth, Environmental and Space Sciences".
2.The repository accepts submissions from the global scientific community, supporting a maximum single file size of 4GB and an individual cumulative upload limit of no more than 3TB, with the entire process free of charge.
3.Data users must register and provide information such as email address, institution, and name to access data; data depositors can independently CC BY 4.0 to license their datasets.
4.For sensitive data, the repository offers two types of controlled access: online access requires submitting an application to obtain data directly, while offline access requires filling out an application form, which will be sent to the data provider for review and approval before data is granted.
5.Confidential peer review of hosted datasets is supported. After users complete metadata and submit data entities, administrators review the metadata. For metadata that meets formatting requirements, the dataset is sent to the "Datasets Pending Review" section in the reviewers' user space, allowing reviewers to log into the platform to download and review the data.
6.After a dataset is published, a DOI (Digital Object Identifier) is assigned to it. Users can link this DOI in their papers to achieve the binding between the dataset and the paper.
7.Datasets cannot be deleted after publication but can be modified; modifications will generate a new version of the dataset, and the repository has established a version management system.
8.DOIs are assigned as unique identifiers for datasets. Regarding data upload support: files smaller than 500MB are recommended to be uploaded online, while files larger than 500MB are recommended to be uploaded via FTP. Metadata management adheres to the ISO 19115 standard and supports submission in XML format.
