Research Data Archive
Research data are gems for the scientific community and society as a whole. Data should thus be accessible after the project is completed, not only for the reproducibility of the results but also for further re-use. Therefore, funders and policymakers are supporting Open Science policies, requiring data to be preserved and Made accessible once the project is completed. Similarly, research institutions are adopting more and more Open Access policies.
To ensure data are reusable, data must be archived. Archiving is not like data storing. Archived data must be persistent (i.e., should not change, should have Persistent Identifiers) and discoverable (through metadata). As required by the FAIR principles, archived data should be accessible by humans and machines to allow the actual reusability of the data.
The Research Data Archive is an archive service that provides long-term storage for research data and is compliant with the Open Archival Information System (OAIS) reference model.
The information about the stored data (metadata) is publicly accessible and some of the metadata is distributed and harvested by other services.
Data in the Research Data Archive are self-uploaded and self-curated.
Open Science and Open Access
The Research Data Archive has a mandate for Open Science and Open Access, and we strongly recommend giving public access to your archived datasets. However, the Research Data Archive also supports restricted access in specific cases, subject to yearly revision. The download of the open-access datasets is anonymous, and the default access license applied to publicly accessible data is CC By 4.0.
Sigma2 provides published datasets with persistent identifiers (PIDs) using the DataCite DOI service.
You can get a DOI for your dataset before your article is published by selecting the "paper in preparation" option when creating a dataset. We guarantee the persistence of the data up to 10 years after the publishing date.
Metadata for searching and discovery are based on the Dublin Core metadata standard.
Next-Generation Research Data Archive
We are now designing and developing the next-generation Research Data Archive. The new version will support data with different access and security requirements, in addition to better support for metadata, DOI minting, scalability, downloading/uploading workflows and FAIR features in general.
Approved academically funded researchers will be allowed to deposit published research data in the archive. Everyone can download data anonymously.
What’s in it for me?
Research Data Archive is specifically suited for:
- Archival of large datasets
- Archival of data stored on NIRD Active Storage
- Publishing and reusing
- Machine actionable data and FAIR data
- Long term preservation
Data can be downloaded and uploaded free of charge, regardless the size of the dataset.
Download is anonymous and through the searching web-interface.
For depositing data, you must submit a request for access through the web user-interface.
By depositing data you do it under the condition defined under the Depositor agreement. In summary the agreement is divided into two parts:
Research Data Archive Responsibilities
- To ensure the dataset is managed according to the license agreement.
- To ensure users of the dataset are aware of the access license. The archive encourages data to be made as free from restriction as possible and suggests data follow the CC By 4.0 license.
- To ensure approved users can access the dataset for the duration of the agreement (10 years from the date of submission).
- To ensure the dataset does not contain illegal content and that the data collection does not breach privacy or data protection laws
- To ensure that the dataset abides by copyright and publication restrictions
- To ensure permission from all stakeholders has been obtained to deposit the dataset
- To ensure sufficient metadata is supplied with the dataset to enable discovery and reuse of the dataset
- To have read and signed the depositor license agreement
The Research Data Archive going forward
Below you find the roadmap for the development of the Research Data Archive. The roadmap is continuously updated, and tasks may move forward and backwards if priorities change.
NIRD - an eco-system of storage services
NIRD – the National Infrastructure for Research Data is an eco-system of storage services designed to support scientific research in every step of the Research Data Life Cycle. You find services for:
- Data planning: EasyDMP
- Data collection and storage: NIRD Data Storage
- Data analysis: NIRD Service Platform
- Data preservation, archiving and re-use: Research Data Archive
About the national e-infrastructure services
Sigma2 works closely with the universities of Bergen, Oslo, Tromsø and NTNU to operate the national e-infrastructure services. The collaboration is called NRIS (Norwegian research infrastructure services). It is the NRIS staff who ensures that all researchers who use the national e-infrastructure services get quick and easy access to domain-specific support and related activities.
Together we work to fulfil our vision We enhance excellent research for a better world.
