It&#x27;s pretty shameful that so little effort was apparently put into preserving these. Why bother doing this if they&#x27;re going to just put them on a disk and let them rot for 30 years. As data become more sophisticated it seems to be harder and harder to archive them in formats that aren&#x27;t obsolete within a few years. I can go to The National Archives and look at a document that&#x27;s nearly 1000 years old (or visit <a href="http:&#x2F;&#x2F;opendomesday.org&#x2F;" rel="nofollow">http:&#x2F;&#x2F;opendomesday.org&#x2F;</a> ), but the &quot;new&quot; version is unreadable less than 30 years later. What can be done about this? I&#x27;m assuming people must be investigating future-proof archival formats.
