1. Preparations

Circle icon symbolising data material. Before you begin, you should go over your research material and think about which parts of it that need to be included so that someone else can understand and reuse the data.

Prepare the data

SND’s services allow you to share digital data from various research disciplines. This means that the research data can be anything from survey data to biological sample data, as long as the material is used for scientific analysis.

It’s important that the data you choose to share are structured and documented in a way that is intuitive to understand for others. The data should also have a file format that is either open and/or commonly used in your field of research. You can read more about how to organize and document data on our pages about data management. We have also compiled a guide for choosing a file format.

Datasets containing personal information may only be documented and shared through SND’s research data catalogue if your organization and SND have an agreement for this. Here you can read more about which organizations offer their researchers this possibility and how it works in practice. If your organization does not have an option for sharing datasets with personal information through SND, you need to ensure that data are anonymized before you describe and share them. You can read more about anonymization here.

If you’re going to make data from a research project accessible elsewhere, you can still describe them with SND so that they become visible and searchable in the SND catalogue. These data will need a PID, or persistent identifier, a long-lasting reference to a landing page where the data are described and where there is information about how to access the data. Here you can read more about choosing a level of accessibility.

Prepare documentation files

In order to make it possible for other people to understand and reuse research data, it’s important to add the documentation that belongs with the data. Reports, variable lists, and README files are some examples of documentation that is of great help if someone wants to do further research on the data you share. You don’t have to share everything, but think about which documentation files that contain information that others need to be able to analyze the data correctly.

Examples of what may need to be explained in documentation:

  • what different codes, abbreviations, variable names etc. mean
  • which definitions that have been used for coding and markup of the material
  • which methods that have been used to collect and process the data
  • which legal, ethical, and other restrictions that limit how the data may be reused.


Here you can read some useful recommendations before you make your data accessible.
