This White Paper is the result of a cross-institutional collaboration between Scottish and German researchers, artists, and programmers. The volume brings together historical, theoretical, and digital research into archival practices of storing and dealing with »Live Art Data« in a comparative approach that encompasses both historical and contemporary practices. It is interested in data that is produced in theatres and other cultural venues, in theatre pedagogical projects, by performing artists, and their audiences. From an interdisciplinary perspective, the White Paper looks at archival configurations and relations of performative data in teaching and information infrastructures today, focusing on four aspects: historiography, theory, digitalization, and the international dimension.
