Digital Domesday Defies Doom 176

Posted by michael from the obsoletion-defeation dept.
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."

          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 [harvard.edu], 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.

The reason I keep citing beowulf (no, I don't have some computer-cluster fetish) is that it is basically the only surviving example of old-english, or so I was taught. If you listen to it, you can really see how in just 1200 years, the language has totally changed.

              • Yes, that might be true. Nowadays, for the first time in history, it's possible to record the actual speech (as opposed to symbols for speech). But, by the same token, the advent of the internet will only speed language evolution. For the first time, it's easily possible to sit down and communicate with someone half a world away. That will almost certainly encourage language homogenization, but that still means change.

    RetroBeep [retrobeep.com], a retrocomputing museum at Bletchley Park (near Milton Keynes, close to London) has the VL-reader and a BBC micro. The proprietor (John Sinclair, whose son is also active at the site) discussed the Domesday project when I was there in May 2003. I'm not sure if there's a copy of it there, but they did have the hardware, and were trying to connect one device to the other.
  • Next time use public domain file formats and document the hell out of them using Dos-CP/M text.
    (Meaning CR and LF)
    It's universal enough. Everyone uses one or the other some times both. Should continue to work well into the future.
    (After all 7 bit ASCII text is almost 50 years old.)

    Document the formats in ASCII, Englishn(psudo code), French, German, Klingonis.. and list Klingonis as the offical laguage of earth at the time. Just to mess with peoples heads.
    Then maybe we can wait a whole 50 years before havi
  • As a storage technology, LV-ROM has been superseded by CD-ROM and DVD, leaving the BBC Domesday discs perilously close to becoming unreadable

    Am I hearing this right? They make it sound like they only had 1 copy of this on LaserDisc - and since everyone's players were going to shit the content was in danger of being lost forever. ???

  • Just think of all the nasty things a terrorist could do with those disc(s). It's a threat to national security! It's a good thing we have nothing like that here in America... HA
  • Just say its pirated warez, throw it up on a torrent, kazaa, winmx, or whathave you, and it will last for years. ;P
    look at the www.textfiles.com archive. :)

    I was at school when the Domesday project was being built, in fact my school was one the schools responsible for covering part of Carlisle in Cumbria.

    Our school bough one of the Domesday kits and on the first day all the teachers were bringing us through in to the library class by class to show it off. This was until one of the teachers dropped one of the discs and it shattered, bearing that in mind I am very surprised there are still discs in woking order after all this time.

    I would hope now that they will work on some of the other discs that used the Domesday hardware. I vividly remember a disc that featured an interacitve film. Basically the topic was about wathching a group of kids mucking around and every 2-3 minutes it would freeze and various options would appear over the characters, e.g "Simon calls Peter stupid". Depending on what you chose (using the track ball) the film would take a different path, either they would all go home happy or they would end up in some sort of trouble. Never mind the brainwashing apsects of the film (i.e. don't misbehave kids), the technology was trail blazing. This was in 1987! Years before DVD and even now I've seen very few interactive DVD films.

    Aparently there was over an hour of film and 4 possible endings to a 15 minute program on one of those discs. Whats more the system was very quick and totally foolproof.

    As an 11 year old obsessed with technology I was in awe of all this fancy equipment, Domesday wasn't just a great archiving project it also introduced some fancy technology which even today seems new fangled.

    What the BBC and their partners should have done is to add new material to the Domesday archive every 5 or so years. As well as the obvious enrichment of the archive, this would also mean there was a chance to update the technology in steps in order to keep track with data storage devlopements. Instead once it was finished it was forgotten about, meaning 15 years later when people realise the value of the project you have to get university's on board to make sense of the storage medium, data and software. That would have been a much better way to preserve the data.
