Digital Domesday Defies Doom
Hulver writes "The BBC Domesday project, originally completed in 1986 and under threat (as reported in this old slashdot story) has had its data recovered. The contents of the laserdiscs have been put on DVD, and new programs written so that PCs can access the data. Interestingly, most of the images and films were not recovered from the laserdiscs, but were instead re-digitised from the original analog films at a higher resolution than the laserdiscs contained. Full details of the recovered data are at the Public Record Office website."
Let's see how quickly it happens.
This article reminds me of something else I read - that the DOE is currently paying good money for people to help design a warning for Yucca Mountain (the giant nuclear storage facility out in Nevada). That one has to last as much as 100,000 years, albeight it has to store a lot less information (stay the F*** out). I wonder what kind of overlap there would be between the two?

.flac, so I can be laughing in the distant future when everyone has crappy mp3s just because they wanted to save some space decades ago when 700 meg was a lot.
This is why I have all my CDs stored as

Language drifts and changes. Pick up a copy Beowulf, circle AD 800. Chances are you won't understand a whole lot, it's written in old english. What with the great vowel shift, the meanings of most of those words have significantly changed. Now, instead of 1200 years, imagine what 100,000 years of language evolution would do to such a warning. That's why ANY warning they choose will probably be pictoral, not script.

michael, you font of knowledge you. I wondered what the hell 'defeation' was so I Googled it. I must say I understand what Google is suggesting.
...re-digitised from the original analog films at a higher resolution than the laserdiscs contained.
That's great as long as the film hasn't degraded to worse than the quality of the laserdisc images and the resolution is there to begin with.
The first thing that struck me when I went over was...where's my copy? This was put together as an educational tool using public money, but now there's only one copy of it in Kew Gardens, London? Why can't I just download it? All the data's public domain anyway.
As it happens, I don't live that far from Kew Gardens and so will probably go to see this. But what I'd really like to do is download the lot and use it as a referece tool at home. Or perhaps accessible online.
Incidently, no word on the formats used to rescue it. It now has a Windows interface - good news, but what about people running other things? That's not a trite statement - they already came close to losing it once in just fifteen years, and in fifteen more years' time I'll guarantee you that it won't be XP on people's desktop. Need to have the formats available so that people can write their own interfaces to it.

Domesday Book, vellum and ink, still readable after 900 years.
Domesday Book II, Laser disks and computer files, in need of rescue after 17 years.
Progress ?
I think you've hit on a really insightful idea. I'm reminded of a quote from Newsradio: "You can't take something off the Internet - it's like taking pee out of a pool."
The guarenteed way of protecting data against time is to make lots and lots of copies. The internet is the perfect medium for that. So yes, why don't they put it on the internet?

Becasue they are stupid, probably.
The ironic thing is that because they have decided to convert it to a proprietary Microsoft format, they will probably have to repeat the exercise in another 15 years. Bloody idiots.
It's clear that any specific format will last for a while and then be obsoleted within a decade or so.
Therefore transferring the information from format to format automatically as new and cheaper solutions arrive. This means a process and to simplify and reduce costs, some automatic tools to do the job.
There are hierarchical storage management[1] solutions around which can do this for you, Tivoli do quite a good one, but, because we're talking long term, the software really also needs to be cross platform and open source.
