How to open research data

There are several reliable national and international data repositories that researchers can use to deposit their research data for free. In case you choose foreign data repository remember to take care that the metadata is produced also to Etsin the Finnish research data finder.

UEF eRepository (UEF eRepo), the open access materials repository of the University of Eastern Finland, contains self-archived versions of academic articles and metadata of research data made available by our researchers. UEF eRepo harvests the metadata of research data from several different data services. Automatic transfer into UEF eRepo is possible from EtsinZenodo and EUDAT. In order that the automatic information transfer succeeds, it is important that the university is mentioned in the metadata correctly. It is recommended to use “University of Eastern Finland” for affiliation. 

When making research data openly accessible, the data needs to be in a form that an outsider can understand and utilise. A thoroughly devised data management plan is instructive already in its data-gathering phase and makes it easier to open. Data to be opened requires being a simple and explicit unity. You would do good to publish your research data in such a data archive that potential users would locate easily.

Opening data step by step:

  1. Choose the data or the part of it that you planned to open.
  2. Find out, if there are any ethical, juridical or contractual limitations to open the data.
  3. Describe opening the data in your data management plan in order acknowledge the requirements to open it when gathering your data. Define the phase of the research project in which you wish to open your data.
  4. If needed, anonymise your data.
  5. For your data, it recommended to choose an open file format which requires no commercial software and which is compatible with as many operating systems as possible.
  6. Make sure that metadata is available to locate your data. Describe the data produced and obtain persistent identifiers (URN, DOI) for your data items. You can obtain a permanent identifier through the Etsin service or data repositories or archives.
  7. Define the rights to use your data by licensing your research data. For open data, the machine-readable standard format license CC BY 4.0 is recommended. Metadata for describing the research data is recommended to be licensed with the CC0 consent. For computer software, the MIT License is recommended.
  8. Make your data openly accessible by storing it into an open data repository or archive (data archives of universities, research institutes, national or international discipline-based or general information archives) or by publishing it in open data journals.
  9. Advertise your open data in social media (e.g. ResearchGate,, Mendeley) and add the open data information into your CV, publication list and your website.

Ethical and juridical matters may limit opening research data in full extent:
