An Abstract Machine Approach to Preserving Digital Information

Preserving digital information for a very long time is difficult even when using a durable passive storage medium such as photographic film stored under the right conditions. On film one can combine analog descriptions, that is, visual and thus human-readable text and diagrams, with encoded digital...
