DARIAH’s Open Science activities explore and foster domain-specific pathways to the open research culture. This includes promoting innovation through new networks and collaborations; supporting uptake of new research and publication practices through reflection, creation and diffusion of high-quality new knowledge, skills and technologies as well as building infrastructural enablers of open research practices. The impact of these activities primarily manifest itself in changes in research culture; in changes in the EU research policy and it also enables the DARIAH member countries to collectively attract funding through European partnerships to address the gaps in the Open Science landscape together.
