Robust Hyperlinks was even a Slashdot story, a BBC News story, and other press.

Here's the blurb from Slashdot: "URLs can be made robust so that if a Web page moves to another location anywhere on the Web, you can find it even if that page has been edited. Today's address-based URLs are augmented with a five or so word content-based lexical signature to make a Robust Hyperlink. When the URL's address-based portion breaks, the signature is fed into any Web search engine to find the new site of the page. Using our free, Open Source software (including source code), you can rewrite your Web pages and bookmarks files to make them robust, automatically. Although Web browser support is desirable for complete convenience, Robust Hyperlinks work now, as drop-in replacements of URLs in today's HTML, Web browsers, Web servers and search engines."

The technical Robust Hyperlinks paper of 4 years ago is now at archive.org.

It would be interesting to read a more technical description than just a popular news story to see if Peridot does more than just store a different signature/fingerprint. It would be erroneous if Peridot's patents claim to have invented the idea of fingerprinting web pages to help fix links to pages that have moved or changed.
