When the Department of Media and Performance Art collects and exhibits time-based media or performance, caring for and properly installing such work is a collaboration between the artist and the Museum. Time-based media commonly uses video, film, audio, and computer programs as platforms for creativity. Often such artwork is digitally based, and it depends upon technology that may become obsolete. In the case of performance art, the ability to re-perform the work mainly relies on the artist’s memory, with the aid of documentation. Both time-based media and performance are therefore mediums in which individual works are often replicated, migrated, or emulated in order to ensure their continued existence.
