Digital Domesday Rescued By Emulation 395
eefsee writes "The BBC announced that the Digital Domesday project which had become unusable has now been revived thanks to the successful emulation of a 1980's era Acorn computer. Folks at Leeds University and University of Michigan did the emulation work. This is just one early indication of how difficult it will be to maintain our digital heritage. Note that the printed Domesday Book, on which the digital project was modeled, is still quite accessible after almost 1000 years."

See? This is why we need DRM. If there were proper DRM going on then of course it would have been recoverable! We would just need the exact system(nope, can't change the processor, or the video card, or the hard driver) in order to recover it!
See, doesn't DRM help us all?

'The software and hardware needed to access the Domesday discs is to be deposited at the Public Record Office once the project is completed.'
This is all fine and good, but it has already introduced the problem we'll face in approximately 2015:
We're going to have to create an emulator for the emulator.
And so on, ad infinitum. What we really need is some universally acceptable method to store digital data that isn't likely to decay or fall out of favor in the next ten years. That, I'm afraid, is a difficult proposition.
I just hope the emulator's emulator works.

The BBC wanted a micro which they could use in their educational stuff. They went to Acorn, who was a successful manufacturer of the Atom [planet.nl], and basically they agreed that the next generation computer, which was to be called the Proton could be called the BBC Micro. This gave Acorn exposure and extra sales, and the BBC the machine they were looking for. For about a decade, you saw BBC micro's popping up in BBC shows including Dr Who. Acorn later made the Electron, and then the Archimedies, before going bankrupt.
Therefore the BBC do not own the copyright on the ROM's in the BBC micro.

Original Domesday is not quite accessible (Score:5, Insightful)
Not really. I saw one volume of the Domesday book at the White Tower back in 2000. It was sealed under a sealed glass box, and you could only look at the two pages it was turned to. I would have tried to get access to it under the box, but there were these guards that looked quite intimidating and they kept saying "Move along..."
Even then, I could barely make out the cryptic scribbles. Sure didn't look like English to me.
At least with a digital version they can make infinite copies of it and distribute it to anybody interested, unlike the paper version locked up under a glass box.

Oh, that's right, it didn't, and before WINE the term 'emulation' was more generic and didn't create ridiculous non-dictionary distinctions.

The real problem is that people don't look any further than right here, right now. All that's required to preserve digital data for future generations to revere or vilify is an effort to keep migrating it onto future media and to publish the method of reading the data along with it. Software formats come and go, there are probably software packages that can't even reliably read data using older versions of that software package.
The specification for the format in which the data is stored is the Rosetta Stone of the 21st century. Make this open and data can live in perpetuity.

You mean linux natively supports DLL (Dynamic Linking Library) and PE (Portable Executable) binary formats?
WINE emulates the Windows environment. It doesn't emulate an x86 or any other hardware directly, which is why it won't work under PPC linux, and why they don't want to consider it an emulator.
It is, however, in the logical and literal senses, an emulator. It's just not a hardware emulator.

To be kept available future data archives will need to be copied over and over. They will have to be copied in bulk, there will not be the man power to do specials on anything.
What am I trying to say: this problem will get worse, worse than you can imagine. Well defined, simple Open standards for data is a must for the basics. Well defined, simple Open standards for Open Source applications to implement anything richer - these applications growing gradually over time, but maintaining backwards compatability. I still use troff and can still maintain/print documents that are over 15 years old.
A proprietary future will be much poorer than an Open one. A future that overly controls copying will be much poorer than an open one.
All of the numbers above are probably an underestimate.

For example, we don't miss any of the treasures of the Roman empire lost under Constantine, Justinian and his successors when the newly ascendant Christians went on a Taliban style orgy of destruction, smashing up anything they considered "pagan" or "unacceptable".
And scholars of Rome *certainly* don't miss any of the works held in the libraries of Rome that were destroyed by the Gothic invaders before the so-called dark ages.
Nor does anyone regret that poverty striken Icelanders took to using ancient manuscripts for dress patterns and firelighters in the 19th century. Nope, didn't lose much there at all.
Hell, we don't even miss all those Egyptian writings destoryed in the 19th century. Or by the Aswan Dam project.
And of course, accidents never happen. Just forget about that little fire in the Library of Alexandra.

Yet another reason to use open source (Score:3, Insightful)
As the GNU project says, "source code" is the preferred form for modification of a work. For this project, the source code for the display program might be BASIC or assembler, but that's not important. What's important is the text/image/video/audio content, and the source form for that content might be XML PNM (no lossy compression), uncompressed AVI and WAV files.
Converting the original, BBC-Micro specific program into a modern source format will eliminate the need for a special or unique system to access that content.
Furthermore, distribution costs on the Internet approach zero, so that work can be made widely available to everybody, not just a few schools or visitors to a museum.
Over time our popular formats such as JPEG and AVI files will become obsolete, so the work must be converted into that newer form in future, possibly ad-infinitum. At least those future conversions will occur from one well-known and popular format into another.
They haven't really learned from their efforts, have they?
So here's the new reason to use open source: It is important to preserve our digital heritage, and using source code is the best means we have of making works accessable and compatible with the computers of the future.
