Lockheed Chosen For Electronic Records Archives
TrentL writes "How will we be able to read 1990's email messages in the year 2090? Will GIF files still be accessible in 2105? The US National Archives - tasked with preserving records "for the life of the republic" - has chosen Lockheed Martin to solve exactly this problem. Lockheed was awarded the $308M Electronic Records Archives contract after a year-long design competition. Full Disclosure: I worked on Lockheed's demo team."
The specs could easily be lost over a long period of time, and it's very hard to reverse engineer algorithms from scratch (given that in 100 years, newer and more optimal algorithms than, LZW will be used). It's predicted that the only image format that will still be around in 100 years is ppm, simply because it only takes about half an hour to implement from scratch!

This example of format obsolescence just popped into my head. Back when Commodore-Amiga was a going concern, the IFF-ILBM graphics format was pretty widely used. It was a nearly universal standard on Amiga.
A fair number of artists and video producers used Amigas. One of Amiga's advantages was that practically all the graphics programs used ILBM format, which meant you could easily feed the output from one application into another, and then into another. It was good, and it wasn't all that many years ago.
Just trying finding a program on Mac OS X or Windows today that can read IFF-ILBM files! Go on, try it! Photoshop, for one, doesn't have a clue about them. The best you can hope is to find some obscure freeware IFF-to-PNG converter that someone has hacked together.
Another example: It's getting harder to find apps that play "tracker module" music, and the programs that are available tend to be awkward and unreliable. Everything went to MP3, and mod music was quickly forgotten.
So if the idea of today's commonplace formats becoming unknown in the future sounds far-fetched at all. . . It's not.
Even that's pretty generous IMHO. In my experience, recent blank CDs (and DVDs) are lucky to make out 18 months, and many of mine are delaminating or corroding after only 12. I've now gotten into the habit of burning two copies of everything I "archive", and re-burning them every 12 months. Thus far I've had errors, but never errors in the same place on each copy.
Contrast this to the good old "Kodak Gold" CDs I was burning onto back in 1996, almost all of which are still readable with 0% errors...
