Will we need cyber archaeologists.
Looking at it, its the oddesd of things. This flimsy plastic box with two round holes in it, seems to come from another age. A brown warn little plastic tape worms itsself from one side of the container to the other. Only 20 some years old , the cassette is as obsolete as the dinosaurs. Yet a few weeks ago my dear aunt called me up in a panic, telling the tale how the evil old cassette player she had owned for so many years had 'eaten' a cassete with a recording on it of my late grandmother singing. I of course offered to go ahead and fix it. After half an hour of poking and prodding with a pair of tweezers and some sticky tape I managed to get the cassette back together. Now I just had to find a cassette player to play it on… It was at that moment i realised .. I did not have one anymore. The thought propped up to me that we store so much information these days on so many carriers, but yet all these media are futile and soon we won't be able to recover anything we stored 10 years ago because technology moves so fast. Will we need cyber archeologists in the future ?
Media are futile.
There are few media that survive the test of time. Even paper turns to dust after so many hundred years, depending on how it is stored. And so are the media we store stuff on today. The average lifespan of a cassette tape, a cd-recordable, a dat tape or even a floppy disk does not even come close to the lifespan of paper. Yet while a single peace of paper can hold out for a hundred years, a DVD rom with all the collected works of Plato won't last a hundred years at all. The loss off information that can occur when our media turn sour is only multiplied by the enormous amounts of data they can carry. To loose a single sheet of paper over the course of a thousand years might be a loss, To loose a thousand documents on a single cd-rom after 10 years is even worse. So what is there to do but to transfer information from medium to medium in order to let it stand the test of time ? Or what if we find the carrier that will last us to infinity.. What format must we use to write our data ?
Formats are fleeting
If your average DLT tape will turn brittle and break in a hundred years you might just have been lucky. Think not of the medium the information is written on , think of the format the information is stored in. Format types like .doc , .xls and so on are even more fleeting then their carriers. You can make your programs backward compatible into the extreme , supporting exotic fileformats of days long gone is a painfull task. Some, like .html, .txt .pdf and .rdf, might be supported for years to come, but what about other, exotic and propriatary standards, formats of backup programs and so on. One might hold a treasured box of data in ones hand but if the fileformat is no longer supported .. How can we ever access it ? Perhaps we will find the key to the format .. but what about the system it was written for ?
Systems are fleeting
It can be even worse. Say we have salvaged the medium and have somewhere found the original application to read it with. What if it only runs on specific hardware ? An evolution that is even faster then the formats and the media , must be the hardware ! What if the information we need only runs on some ancient system like say for example a commodore 64 ? Where to find one ? and even more importantly : where to find the parts if something breaks. Even to this day some "legacy' programs that are still being used in production, run on hardware that is no longer supported by the manufacturer. So what do we have to do ? Store both the information, the media, the original application AND the hardware it runs on in our archives ? What can be so important that we need to go through all this hassle ?
what is important
"So what .." I hear you say ? What if we loose that excell file thats 8 years old ? Who cares ? … But that is just it. We might know what information is important today, but we will never be able to tell what information is pivotal or trivial in the future. The first posting by Linus Torvalds on usenet might have been unimportant, Yett only history will tell wether this one event might be something for the historybooks. The fact is we store more and more information these days on systems, media and in formats that might not stand the test of time. Wether or not something will be important in the future is impossible to tell at this time, thus we risk turning the digital era we live in today, into tomorrows informational dark ages , from which nothing will be remembered in the future.
Cyber archaeologists
I see a new profession emerging. Perhaps starting out as a niche market, later to evolve in something that will turn into an exact science. People who spend their time looking through old digital archives. Who have the skills to work with old legacy hardware, know which side is up on a floppy disk , and God forbid, even speak the language of the old commodore 64. Cyber-archeologists digging through our digital past, being able to unlock and uncover the secrets of the past and bring them back in the light of whatever modern civilisation there might be. A proffesion that holds both the keys to FINDING information and being able to ACCESS it aswell. A trait of archeologists not speaking of the jurrasic but of the "basic" or the "x86" period of the past …
Epîlogue
As evolution speeds up .. so does the regression of the past into oblivion.
I for one do think we will have them in the future. Experts in finding what was stored but yet was lost. Keepers of keys that can unlock the files from our past and bring them back. With the amount of information we produce, the digital legacy we leave behind… its unthinkable that these things would be lost forever in a period of only a few decenia. Prove me wrong .. Digg into your past and find the first digital document you ever made ? Perhaps you"ll need a cyber-archaeologists to complete the task.
