September 24–25, 2015. A conference with experts from Europe and the USA on the current challenges posed by documenting, caring for, and presenting time-based media art. The interest museums and other institutions responsible for cultural heritage have shown in time-based art over recent decades is paralleled by technical changes and technological obsolescence, factors confronting collections with fundamental questions. Digital archiving strongly influences how we deal with video and other media. How threatened works can best be preserved is the subject of controversy, along with which presentation forms are most suitable, the spectrum ranging from reconstruction through to a completely new reenactment. The conference wraps up the first phase of the research project by putting up for discussion the main questions for research and project work. A documentation of the individual talks given can be found on this website.
