RDS-WORM (write once, read many) resources enable storage of research data on the Research Data Storage (RDS). As a storage facility pre-funded by the DFG, there are no further costs for users as long as good research data management is ensured. RDS-WORM (write once, read many) resources can be used via S3 protocol with various tools.


Please use WinSCP, Cyberduck or MinIO Client according to the instructions on the respective subpages. We cannot provide support for the functionality of other applications (e.g. rclone, S3CMD).


RDS-WORM are object-based storage units with "write once, read many (WORM)" functionality for research data. RDS-WORM is based on the same technology as RDS-S3.

When is RDS-WORM an option for me?

  • This resource type is particularly suitable for raw data or other data that must not be modified.


Once allocated, storage space cannot be reused, not even by the project owner or system admins

What changes for me if I want to use RDS-WORM?

Since in this case no metadata can be ensured by Coscine, a request must first be made, briefly describing what data is involved and how it can be ensured that the data can actually be retrieved in the RDS. This can be local or web-based databases, but other ways to keep track are also possible.

In addition, it must be ensured that the data and metadata are stored within the WORM S3 bucket with the knowledge that they cannot be subsequently modified. If you need quota for RDS-WORM resources, you can find the application form under storage space management.

How does metadata management work for WORM resources?

Metadata that, like the associated data, should no longer be modifiable must be stored directly in the S3 bucket via additional files (e.g. README files). Metadata that is maintained via the Coscine web interface remains editable.

What happens next?

RDS-WORM is based on the same technology as RDS-S3, so you can find all further information on the related pages to the RDS-S3 resource.
