On the 7th of June 2018, The National Archives UK held its inaugural digital lecture, delivered by Professor Luciano Floridi entitled “Semantic Capital: What it is and how to protect it”. The lecture was followed by a poster exhibition, showcasing nine cutting-edge digital research projects at The National Archives. This paper aims at giving a distinct overview of The National Archives’ digital research priorities, drawing on examples from the active and recently completed research projects, which were displayed at the exhibition (...) on the 7th of June 2018. The focus of this paper is to discuss the research challenges that we are facing as we seek to become a second-generation digital archive, that is digital by instinct and design. By placing a particular emphasis on the conceptual and epistemological challenges relating to trust and openness, the paper suggests that research is the key for us as a rapidly evolving digital archive; enabling us not only to inform but also innovate around the forthcoming digital challenges, and helping us to define future directions and lead the shaping of the future archive.
