Evaluating Interactive Archives

The concept of reproducibility has been the keystone of both ancient and modern scientific methods. In spite of this, digital science has recently been put to task to improve its failing record of repeatable experimentation. A plethora of digital archives have appeared in response, yet the community has not defined the end goal. There exists no means of comparing or evaluating digital archives nor the quality of preserved software, and thus no means of knowing if the tools are valid toward that goal. A metric for evaluating software sustainability is provided and used to define a metric for evaluating and comparing interactive software archives.
