In the preservation of digital art, documentation is filling the gaps in between manifestations of a piece. When an installation is set up in a gallery, digital art is migrated from one server to another, or generally, when an artwork finds itself in a technical environment that is different from the one it was made in or made for, documentation plays a vital role in guiding curators, preservation specialists, and exhibition technicians. This chapter proposes that specific types of documentation can become part of an artwork’s manifestation, and that, over time, artworks can be moved into a mixed form that is part full performance and part documentation.
