Algorithms may well get lost, so I'd advocate zero compression - straight text or some lossless image format (bmp, tiff etc); but I would be more worried about the longevity of the actual storage medium itself... I seem to remember reading an article about a US-built 'time capsule' wherein straight text had been etched into some sort of corrosion-free metal along with a codex (maybe someone else may have heard of this). Not too practical for us little people, I know :-)

Does anyone know how long a recordable CD/DVD will actually last if well kept? At least it should be EMP-proof
