So you’ve learned how to backup your del.icio.us data with something like this:
curl -o delicious.xml -u username:password "http://del.icio.us/api/posts/recent?count=10000"
(Well, the 10000 most recent entries anyway!)
Obviously you run some sick and twisted Perl code on it and you get an HTML page that lists all your posts, by tag, with posts displaying under each tag they belong to…
Anyway, that’s what dir.licio.us does…
(It ignores the timestamp and extended field, but you could hack those in if so inclined…)
