      Step back, though, and think for a minute about the "house of cards" upon which that Word document rests.

      It rests on
      1) Physical storage medium -- whether this is Flash, Hard Drive, Optical Medium, [NV]RAM, etc., all these technologies may be very difficult to retrieve data from, especially if the level of technology happens to go down in the future (say, global thermonuclear war). Even if data is retrieved, there's no guarantee that it's intact after 1000 years (the dyes in CDs will have decomposed by that time; the Flash drives will have leaked all charge; the hard drives will have randomly demagnetized over that period of time, etc.).
      2) 8 bits per byte, 32 bits for most integers in the file, IEEE specification for floating point numbers, ASCII, Unicode, GB2312, etc. -- encodings for our numbers, letters and even bit-packing of binary data will affect retrievability. It would be difficult, I imagine, for some futuristic person to wander along (with possibly a different language) and attempt to interpret all of that.
      3) File format -- the MSOffice OLE2 format is incredibly complex, perhaps overly so. An OLE2 file takes the form of a miniature filesystem, with a Fragment Allocation Table, 512-4096 (variable) sized blocks, a master Double-Indirection FAT, sub-block allocation, etc. Fragments within the OLE2 container are assembled into "files" or streams in this file system and then parsed. Sure, it makes for wickedly fast saving times (since you can write to changed portions only and add fragments as needed, like a real file system), but it also makes it damn hard to parse, compared to plain text formats like XML or RTF.

      There are many more layers to this system, but that's a basic overview of what a researcher (or someone else) 1000 years from now will have to contend with.

      Sure, if you're looking at just extracting text, you can skip the last layer by simply going in the file and pulling as much out as possible, much like I used to do with corrupted Word documents. However, if you're looking to retrieve images, videos, archival audio, etc. then your job is much harder.

      You don't understand the format then. Office Open XML is the ultimate in 'open' because they define it so you can embed any other document, in whatever format, within it. Obviously, the UK National Archive must use this 'master' format for storing all their existing documents in.

    It seems to me that this is really a nonproblem--OOo is compatible with lots of "dead" formats (or, can read them at least), as well as many other open source office programs. I can't imagine they're going to begin throwing away this compatability--it isn't like it takes extra coding (as far as I know). Also, I have found Microsoft Word's "Extract text from any file" to work pretty well (I had a roommate with a corrupted Mac-formatted disk that had his deceased grandmother's journal on it in some old Mac Word file (a format still readable in Word, but the disk was corrupted so I couldn't just open the file). I popped it in my parents' now deceased iMac and the only program I found that opened it was Word, using the "Extract text from any file" function. I emailed him the journal and he thanked me profusely).

    Also--as noted, the OOXML format is a nonsolution for this nonproblem. It seems like it would be a waste of effort--why convert a bunch of files to a format that may die just as quickly as any other format, when you can just leave the file as is and open it in OOo (assuming I'm correct that they won't stop read support for dead formats)?

    Also, it seems to me that no current format or any future format will ever solve this nonproblem because formats will always change as new functionality is continually added. The better solution is to keep this a nonproblem by having open source software that can read old file formats.

I know MS bashing is fun, but come on, we do it on just about every other thread... lets have a day off.

    To kick things off here's one:

    Keep EVERYTHING in the simplest possible format. ASCII would seem sensible, since its the content we care about, not the formatting. (although that wouldn't help our Asiatic brethren much). Then Keep decent records of HOW you can read that format. With examples of the software and hardware. do this bit on PAPER. V. Tough Paper (or rock, or plastic or whatever). Update the explanations every other year, to put it in language the next gen will understand. Maybe also have instructions on how to translate the simple format to less simple things.

    The idea that an institution like the British Library, which is run by people bright enough to make you look like a dead match, would accept such a preposterous idea is insulting.

    Unfortunately, those bright people don't get to make technical decisions.

    The British Library recently introduced SED, an electronic document delivery system. With SED, you can order electronic copies of journal papers and articles from their archives. Great idea! Previously, you had to wait for the documents to come through the post, and that would take a week or so. Now you get them by email in a couple of working days.

    Except that the documents are crippled by Adobe DRM, which imposes the following restrictions:
    • You can only view them using certain specific versions of Acrobat Reader (6 or 7) - the latest version is not recommended.
    • The software only works on Windows 2000 or XP. No Linux support, no Mac support. Vista might work, but again, it's not recommended.
    • You can only look at each document for a limited time, and you can only print it once.
    So, if you want to use the service, you'd better hope that you have (a) the right version of Windows, (b) the right version of Acrobat Reader, (c) a reliable net connection, and, most importantly, (d) a very reliable printer that won't chew up the document. Unless you're a filthy dirty pirate, of course.

    If Adobe managed to convince the British Library to put up with this ridiculous system, I am sure that Microsoft will have no difficulty convincing them about their archive "solution". If SED is anything to go by, it'll be another awful implementation of a great idea.

    No, they shouldn't. You usually want 3 formats:
    - the original format of the document. Whatever whichever idiot happened to write (or record, or video) it in, you absolutely want the original in your records.
    - a searchable format (eg OCR'd text from scanned image docs)
    - a rendered format. (eg an image or pdf, or svg - something open enough that you can continue to show how the doc would have looked). The appropriate rendered format varies. Paper is not an appropriate format for storing CCTV footage, for example ;)

    If you're very, very lucky the original is both searchable and viewable; like, say, HTML. It gets more complicated too, because you often want to store a redacted copy of the document (think of the Onion story 'CIA realise they've been using black highlighter pen all these years') and you want that searchable too, so you have to keep a redacted searchable format too... and of course, some of the records are on actual paper. Have you started worrying about the fading inks in the originals yet?
