The Digitising Contemporary Art project has released Guidelines for a Long-Term Preservation Strategy for Digital Reproductions and Metadata.
Here's an excerpt:
These Guidelines for a long-term preservation strategy for digital reproductions and metadata explains how to preserve digital materials such as text, images and video. It gives a theoretical introduction to the subject as well as practical examples of how to manage a collection of digitised and born-digital artworks. . . .
These Guidelines are intended to be used by participants of the DCA project, but can also be used by other institutions in the process of digitising their collections. The different elements of digital preservation are explained in a basic and accessible way that is not too technical. Together with some examples from real life situations and recommendations for practical tools, this approach should give the basics needed for collection managers to create a suitable preservation policy and plan. It is important to keep in mind that digital preservation is a continuous process that has to be regularly re-evaluated by the collecting institution.
