RECODE will leverage existing networks, communities and projects to address challenges within the open access and data dissemination and preservation sector, and produce policy recommendations foropen access to research data based on existing good practice. The open access to research data sector includes several different networks, initiatives, projects and communities that are fragmented by discipline, geography, stakeholder category (publishers, academics, repositories, etc.) as well as other boundaries. Many of these organisations are already addressing key barriers to open access to research data, such as stakeholder fragmentation, technical and infrastructural issues, ethical and legal issues, and state and institutional policy fragmentation. However, these organisations are often working in isolation or with limited contact with one another. RECODE will provide a space for European stakeholders interested in open access to research data to work together to provide common solutions for these issues. RECODE will culminate in a series of over-arching policy recommendations for a policy framework tosupport open access to European research data targeted at different stakeholders and policy-makers.
