The grand vision for DARIAH is to facilitate long-term access to, and use of, all European Arts and Humanities (A+H) digital research data. The DARIAH infrastructure will be a connected network of people, information, tools, and methodologies for investigating, exploring and supporting work across the broad spectrum of the digital humanities. The core strategy of DARIAH is to bring together national, regional, and local endeavours to form a cooperative infrastructure where complementarities and new challenges are clearly identified and acted upon.
