Open data
Openness of research data increases the reliability and reproducibility of scientific research. It is often possible to use the same data in multiple ways in different studies. However, open access to the data does not require that the data be fully open. For example, it is possible to store the data in secure data archives (repository) so that their reuse requires a research permit. However, just the terminology can be challenging – should we talk about research materials or data? And what should be included in data?
