Open Access to Research Data
The University Library offers guidance on various aspects of research data handling and data management planning.
Research data is a core part of the value creation at universities. Promoting open access to research data is a strategy to make full use of their potential and thereby maximise the impact of research activities in a digital society.
The University Libary provides guidance on various aspects of research data handling and data management planning, please do not hesitate to contact us.
WHY should you make your research data open?
Open Access to research data increases the impact and transparency of research activities. It ensures that the full potential of a research project is utilized and can lay basis for further research, with appropriate crediting of the data creators. Therefore, practices to support good data handling and open access to research data have been made a requirement by funding bodies, such as the Norwegian Research Council and Horizon2020/Horizon Europe. In alignment with the National strategy on access and sharing of research data, open access to research data is part of The University of Bergen Policy for Open Science. Furthermore, many publishers require authors to make the datasets underlying the findings described in their publications available and thereby ensure reproducible research.
"More open access to, and wider reuse of, research data promotes scientific advancement in that it equips individual researchers with a larger pool of data, facilitates replication and quality assurance of previous research findings, and prevents re-funding of the same type of data collection multiple times."

Open access to research data increases the impact
Open access to research data comes with advantages for both researchers and policy makers:
- Articles that link to research data are cited more often
- Interlinking data and publications increases the visiblity of researchers
- Data publications can make data available and citable that is not linked with a publication
- Data or analysis tools can inspire new research and create opportunities for collaborations
- Transparency supports research integrity and reproducibility
- Available results allow involvment of citizens and society
- Fewer resources spent on result duplication, thus greater efficiancy for funding bodies
- Building on results can lead to acceleration of the research process, faster innovation

Open access to research data is a requirement
A collection of relevant policies, guidelines, documents, and links.
- Research data must be as open as possible, as closed as necessary
- Research data should be managed and curated to take full advantage of their potential
- Decisions concerning archiving and data management must be taken within the research community
- Research data should be managed and curated to take full advantage of their potential
- All research projects lead by researchers at UiB will have a data management plan
- Students and PhD candidates are encouraged to make their research data available when submitting their master or PhD theses
Norwegian Research Council (2017)
- Research data must be stored/archived in a safe and secure manner
- Research data must be made accesible for reuse
- Reserach data should be made accessible at an early stage [latest at publication]
- Research data must be accompanied by standardized metadata
- Research dataprovided with a license for access, reuse, and redistribution
- Research data should be made accessible at the lowest possible cost [preferable at no charge]
- The management of research data must be described in a data management plan [DMP must be delivered in connection with the revised grant application]
- DMP should comply with Science Europe Guidelines
Horizon 2020 (2016)
- "Data Management Plans (DMPs) are a key element of good data management. A DMP describes the data management life cycle for the data to be collected, processed and/or generated by a Horizon 2020 project."
- The proposal is not expected to contain a fully developed DMP. However,good research data management as such should be addressed under the impact criterion, as relevant to the project.
- Once a project has had its funding approved and has started, you must submit a first version of your DMP (as a deliverable) within the first 6 months of the project. The Commission provides a DMP template in annex, the use of which is recommended but voluntary.
- The DMP should be updated as a minimum in time with the periodic evaluation/assessment of the project.

WHAT is research data - should everything be open?
In the National strategy on access and sharing of research data, publicly funded research data is defined as "all data collected or generated for use for or as a result of publicly funded research activities and data underpinning publications that are the result of publicly funded research activities". This includes both entirely new data and data generated through analysis of existing data (secondary data). In order to take full advantage of their potential, research data should be managed and curated.
To accelerate the research process and to make research results reproducible, also research protocols and analysis software/program code created in the research process should be made accessible.
The main principle of open access ot research data is that data should be as open as possible but as closed as necessary. For example, personal or sensitive personal data as well as data that would conflict with intellectual property rights and commercialization can not be made fully openly accessible. However, it might be possible make some sensitive personal data available in anonymized form or to specific users by defined access criteria and ensuring technical access control.
HOW can you make your research data open?
Data management plans (DMP) are an instrument to support good data handling practice throughout the whole research data life cycle, from project planning over the active phase of research to project conclusion. Archiving data, accompanied by their metadata and a suitable data license, is a strategy to increase the impact of research results and promote reproducible research. The FAIR-principles describe a set of guidelines that ensure that research data can be reused. Importantly, FAIR data does not equal unrestricted access to data. In a project with personal or sensitive personal data, measures to secure the data will be an important part of the data management plan.
Data management plans (DMP)
Data management plans (DMP) are an instrument to support good data handling practice throughout the whole research data life cycle. It describes how data will be collected, processed and made available during the lifetime of the project and after the project has ended. A DMP should also describe how ethical aspects and sensitive data are managed. A DMP is a living document and can be adjusted in the course of the research project. The University of Bergen as well as funding bodies require that research projects have a DMP. You can find more practical information on our page on DMPs. In addition, the University library regularly provides courses on data management planning.
"All research projects lead by researchers at UiB will have a data management plan."
From University of Bergen Policy for Open Science
The research data life cycle
Research data life cycle describes the process from project and data management planning over creating novel data or creating new knowledge based on existing data to publication and long-term preservation of high-quality research data which again can lay basis for new research projects.
FAIR data: Findable, Accessible, Interoperable, Reusable
The FAIR-principles were published in 2016 (Wilkinson et al.) as a detailed set of guidelines to ensure that archived research data is of sufficient quality.
"UiB will promote open access to research data and the FAIR principles in national and international networks and collaborations."
From University of Bergen Policy for Open Science
The FAIR-principles in brief:
- Findable: Finding datasets is the first step of (re)using datasets. This requires metadata ("data about data"), readable for humans and machines, and persistent identifiers.
- Accessible: Criteria to ensure access to a found dataset. Metadata must be retrievable by a standardized protocol, that allows for authorization procedures were necessary. Importantly, metadata must remain accessible even if the data itself are no longer available.
- Interoperable: Prerequisites to integrate datasets with other data and applications. Metadata should use ontologies/controlled vocabularies and include qualified references to other (meta)data.
- Reusable: FAIR should allow for reuse of data. Metadata must be rich, must contain provenance, and follow community standards. A data usage license ensures legal interoperability.
Obtaining all necessary metadata records in the active phase of research, eases the archiving of FAIR data at project conclusion. It is therefore advised to make yourself familiar with the metadata standards and data archives in your research community already during data management planning.
Data management in the active phase of research
Good data management in the active phase of a research project facilitates your future research, eases collaborations, enables advanced analysis methods, and is a prerequesite for archiving high-quality data. Some aspects to consider:
Data storage and backup
- Information about local data storage at UiB can you find here. For additional storage quotas, active storage or cold storage on Billy, see the price list from the IT-department. If you need personal guidance, please contact UiBhjelp.
- Sensitive data from UiB can be stored in SAFE. Please see also the information about personal data and personal sensitive data.
- Active storage of large amounts of data (TB range) is provided by Sigma2, applications run twice per year. The NIRD service platform allows on-site analysis.
- Information about high-performance computing (HPC) at UiB can you find here.
- Use descriptive and informative file names.
- Choose file formats that will ensure long-term access.
- Track different versions of your documents.
- Create metadata for every experiment or analysis you run. Make sure to document e.g. experimental conditions or origin of the data. See the Deposit Guide of UiB Open Research Data or DataONE Best Practices Primer for more information.
- Organize/index your data in a way that allows you and others to easily search for certain files, also after an extended period of time. See the CESSDA Data Management expert guide for more information.
- Consider the annotation in your data files and their machine-readability. For example, save tidy data with each variable as a column, each observation as a row, and each observational unit as a table.
- If you write software code, consider version control with Git. The University of Bergen has its own Gitlab instance.
- Make yourself familiar with the metadata standards in your research community/ in the archive you want to publish your data in already early in the process and make sure to obtain the necessary records. Please see data archiving for more information.
- Data provenance or data lineage describes the historical record of data from their origin over transformations (such as analysis workflows, integration with other datasets) to their publication. Each data point in an article figure should be tracable to its original aquisition.
- Electronic lab notebooks (ELN) can aid data provenance records in some disciplines.
- Analysis workflows should be reproducible, e.g. by using software code for data analysis and controlled computational environments.
Projects with personal data & personal sensitive data
If projects contain personal data or personal sensitive data, specific measures need to taken to secure the data. Describing these measures are an important part of the data management plan.
Personal sensitive data describes a category of personal data that contains information about racial or ethnic origin, political beliefs, religion, philosophical beliefs, trade union memberships, genetic and biometric information, health information, or sexual information.
The University of Bergen Personal Data and Privacy Gateway (Personvernportalen, the Norwegian page is more comprehensive) collects guidelines and legal information that have to be considered when working with personal (sensitive) research data.
Importantly, all student and research projects at UiB that contain personal (sensitive) data must be registered and followed up in RETTE. RETTE collects self-completed project information from researchers and students, research projects evaluated by NSD, and health research projects that have research ethics approval from REK.
Storage of personal (sensitive) data in the active phase of research
The IT-department at UiB has a service for secure storage and access to sensitive data, SAFE.
Other secure storage options in Norway are TSD and HUNT Cloud.
Archiving personal (sensitive) data
Long-term preservation of personal (sensitive) data can be appropriate in certain cases. Some sensitive data may be archived in repositories with technical access control to allow data access only for specific users by defined access criteria. In other cases anonymization of sensitive data could allow their deposition in an open repository. Importantly, if research data is collected with informed consent, data archiving plans need to be included already in the consent forms.
The CESSDA Data Management Expert Guide contains a section on legal and ethical considerations in creating shareable personal data.
The ELIXIR RDMkit has a section on planning, collection, processing, analysing, preservation, and reuse of human research data and contains a collection of relevant tools and resources.
PhD on Track about personal data and sensitive data.
Although the basic principles apply to all sorts of research data, many aspects of research data management are discipline-specific. Some infrastructures provide specific support services for research data and data management-related questions:
- ELIXIR for life sciences. See also the ELIXIR RDMkit.
- CLARINO Bergen Center for language research
- Bjerknes Climate Data Centre for climate research
- NSD for social science research. NSD is the national service provider for the Consortium of European Social Science Data Archives (CESSDA). See also the CESSDA data management expert guide.
- NMDC for marine research

WHERE can you make your research data open?
Publishing research data and their accompanying metadata in a research repository ensures their long-term preservation, findability, and accessibility. Research data should be made accessible latest at publication of the scientific article
Choose a data archive
Community repositories, that are optimized for the needs in a given field of research, are often the first choice to archive your data and make your research data visible and findable. re3data.org is the largest and most comprehensive registry of data repositories available on the web. The registry is curated and all listed data repositories meet defined quality criteria. fairsharing.org is an another, curated registry of research data repositories. Furthermore, the Norwegian Research Council has published a road map of research infrastructures (in Norwegian) that links to many relevant repositories.
Institutional repositories are a good alternative to subject-specific repositories. Researchers at UiB can archive data in UiB Open Research Data and get support in the deposition process.
If neither a community repository nor an institutional repository appears suitable, general-purpose repositories can be used. For example, Zenodo is a general-purpose open-access repository developed under the European OpenAIRE program and operated by CERN.
Although it is requested that data is made accessible as early as possible, embargos on the data release can be appropriate sometimes. Embargo periods and reviewer access are supported by most repositories.
Archiving personal (sensitive) data
Long-term preservation of personal sensitive data can be appropriate in certain cases. Some personal sensitive data may be archived in repositories with technical access control to allow data access only for specific users by defined access criteria. In other cases anonymization of sensitive data could allow their deposition in an open repository. Importantly, if research data is collected with informed consent, data archiving plans need to be included already in the consent forms. You can find more information about human data in the research data life cycle and archiving options here.
Persistent file formats: Ensure long-term access
Research data should be archived in open, non-proprietary formats to ensure long term access to the files. For example, TXT rather than Microsoft Word, CSV rather than Microsoft Excel, TIFF or PNG rather than Adobe Photoshop files. For more examples, see here.
Metadata: Describe your data
Metadata is structured information that describes, explains, locates, and makes it easier to retrieve and use an information resource.
In order to help make your data reusable and accessible to you and others in the future, you need to create and archive accurate metadata along with your data. If you archive your data in a community repository or institutional repository, most often the repository will define the metadata standard. The Digital Curation Centre allows to browse examples of metadata standards by discipline. Furthermore, fairsharing.org holds a curated registry of metadata standards.
Data licenses: Allow reuse of your data
Reuse of data with appropriate crediting of the data creators requires a license. For research data, mostly Creative Commons licenses are used. Licenses on research data should set as few restrictions as possible on the access, reuse and redistribution of the data. Be aware, that attribution requirements might result in attribution stacking.
For open software licenses, choosealicense.com and the Open Source Initiative provide useful resources.
To ensure long-term preservation and allow citation, it is recommended to publish program code that was generated during a research project. Many researchers use Git, a system for distributed version control, to manage their program code. The online development platforms Github and Gitlab (beta) have implemented comfortable release functions to publish code on the general-purpose repository Zenodo, supporting versioning.
Good code documentation is crucial to make program code reusable. You can find more information and a checklist here.
