DANS's activities are centred around 3 core services: data archiving, data reusing and training & consultancy.
Sharing and reusing research data promotes science. Datasets collected for a certain research purpose can also contain answers to research questions from very different research in the same or in another research discipline. This is certainly the case for historical data. Furthermore, new insights are gained by combining datasets, which is impossible if the data are not sufficiently described and available. The availability of research data finally facilitates the reproduction of research, which is an important condition for science.
