Research data are generated through significant investment and long-term commitment. Since collecting and cleaning up data require a considerable amount of effort, not to mention money, it is important to keep such data for future use.
The University of Helsinki has two services for preserving research data: a Databank for retention periods ranging between 5 and 15 years, and a Data archive for long-term preservation (25 years or more). Both services are curated, which means that they include a data selection process.
Research data are stored in the Databank and Data archive in frozen form, which means that their content cannot be edited in neither service. If you need a service where data can be edited, check out the Helpdesk website for solutions provided by the University.
The metadata of data stored in the Databank and the Data archive are published in a data catalogue.
