Saving Digital History

Gavinsblog writes "The Washington Post is reporting that the Library of Congress in the U.S. plans to initiate the $100 million National Digital Information Infrastructure and Preservation Program (NDIIPP). It is hoped that the project will lead to the preservation of data that is constantly changing on the Internet. But I wonder who will choose what is worth saving?" This may remind you of the LOC's effort to preserve and digitize the audio collection in the National Recording Registry.

      My suspicion is that punch cards will make a return at some point. ;) No, really. Not only does it resolve the longevity issue, but it could also solve the issue of obsolete reading hardware (seems to me it'd be easier for a distant generation to rig up a punch card reader than a cd-rom drive). Punch cards are in a rather obvious format as well, if worst came to worst and humanity nuked itself back to the stone age.. in ten thousand years a disc that looks like a mirror is probably harder to translate than a piece of paper with regularily spaced holes.

      The difference being that this archiving is _digital_, though...

      Didn't you pay attention in that IT class when they were explaining the difference between Digital and Analogue? Digital's main advantage is its reproductability. So if, say, the CIC Lib^H^H^H^H^H^H^HLibrary of Congress were to refresh the information once every five years or something like that, then you've got an indefinate storage period. The problem with it is that it needs constant maintenance. The reason this is better than analogue archives is pretty simple... when analogue decays, it's pretty much never going to achieve its original quality. You can do things to try and make it similar, but you're never going to get it as pure as the original.

      With digital archives, you can avoid the decay simply by transferring. This isn't an option really with analogue because once you transfer, you tend to lose quality. But bits are simply 1s or 0s, and digital transfer can be perfect. Throw some md5 checksums in there to make sure that you don't corrupt the data, and boom... you've got perfect digital copy.

      Sorry, but this idea will not fly on a number of grounds. Consider how many punch cards would be needed to save even 4.7GB of data (contents of one DVD). It would take over 50,000,000 cards (even if they did not contain sequence numbers). The creation and storage costs would be astronomical and reading them back in to find any data you wanted would take weeks -- just for a single DVDs worth of data. Further, much of the most useful data (images and sound recordings) are more difficult to store on punch cards than almost any other alternative medium.

      An indefinite storage period is only part of the problem. Even if you keep the 1s and 0s by copying them every five years, file formats go out of scope, and even if you keep the software the file was saved in, the OS that ran it may well be dead (most are, after all) and even if you save a copy of the data _and_ the application that can read it _and_ the OS, what hardware are you going to run it on?

      So its a nested set of problems, with no one solution -- copying, conversion and emulation will all be required.

      There are two major advantages of analog over digital: the first is that inaction over a period of years does not destroy analog material. If you put a stack of paper in a box in the early 90s, it's probably fine. That degree of inaction, however, can be the death knell for digital material. If you put a stack of CD-ROMs or disks away in the early 90s, chances are at least some of that material is gone.

      The second is that while analog degrades slowly, bit-sensitive digital data (encrypted, compressed or executable files) degrades extremely quickly. If you make a mistake handling a book, say, you may end up with one torn page, but if you lose even a small piece of a bit-sensitive file, the entire thing vanishes forever.

We have lots of old backup media (reel to reel tape, 8mm tapes) at work that are probably still readable, but no one knows how the data was encoded on that media (or more importantly,) what information is on which tape.

      Most commercial tape backup solutions have proprietary encoding solutions, and who knows if that company is going to be in business/supported in 50 years. In fact, for true(r) long-term storage, it's recommended to copy the data from the commercial tape backup solution copy to plain old tar.

    Historians of the future will have more information than historians of any other generation. Their problem will be that the miriad of views reflected via this information doesn't mean an increase in the spectrum of political opinion, but the ability of everyone to be opinionated.

    Their worst problem is that the leaders of the day (Bush, Blair et al ) don't stand out like the leaders of previous years. Will anyone rate the speach of Powell or Bush against, Churchill or Kennedy ? Nope. So how to judge politics of today, how to judge what should be stored, we have no leaders of merit, we have only retoric.
