Robust Hyperlinks: The End of 404s?
Tom Phelps writes, "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."
