Query: Transparent Format Migration of Preserved Web Content   The LOCKSS digital preservation system collects content by crawling the web
and preserves it in the format supplied by the publisher. Eventually, browsers
will no longer understand that format. A process called format migration
converts it to a newer format that the browsers do understand. The LOCKSS
program has designed and tested an initial implementation of format migration
for Web content that is transparent to readers, building on the content
negotiation capabilities of HTTP.
