Curators, conservators, registrars and media technical managers from New Art Trust, MoMA, SFMOMA, Tate, have formed a consortium to establish best practice guidelines for care of time-based media works of art (for example, video, slide, film, audio and computer-based installations). Effective approaches to the stewardship of electronic art rely on the blending of traditional museum practice with new modes of operating that derive from and respond to the complex nature of these installations.
