In this paper I am discussing the repositioning of traditional
conservation concepts of historicity, authenticity and versioning
in relation to born digital artworks, upon findings from my
research on preservation of computer-based artifacts. Challenges
for digital art preservation and previous work in this area are
described, followed by an analysis of digital art as a process of
components interaction, as performance and in terms of
instantiations. The concept of dynamic authenticity is proposed,
and it is argued that our approach to digital artworks preservation
should be variable and digital object responsive, with a level of
variability tolerance to match digital art intrinsic variability and
dynamic authenticity
