<br>
<o:p></o:p></p>
<p class="MsoNormal">"We're going to have to build into our thinking the concept of preservation writ large," Cerf added.
<o:p></o:p></p>
<p>One possible solution was what he called "digital vellum", a concept now being explored by computer scientists at Carnegie Mellon University in Pittsburgh.<o:p></o:p></p>
<p>This involved taking a digital "snapshot" at the time an item is stored of all the processes needed to reproduce it at a later date, including the software and operating system.<o:p></o:p></p>
<p>The snapshot could then be used to reproduce the game, picture file or spread sheet, on a "modern" computer, perhaps centuries from now.<o:p></o:p></p>
<p>"Some people make the argument that the important stuff will be copied and put into new media and so why should we worry," said Cerf. "But ... historians will tell you that sometimes documents and transactions images and so on may turn out to have an importance
which is not understood for hundreds of years. So failure to preserve them will cause us to lose our perspective."<o:p></o:p></p>
