URL Shorteners Get Some Backup

URL shorteners are problematical, as everybody knows, but with the rise of Twitter and its ilk they seem to be a necessary part of the landscape. Some of the biggest questions around services such as bit.ly, TinyURL, and is.gd is what happens when they go out of business (as tr.im did last August). Now a group of such companies, organized under the auspices of the Internet Archive, has formed a non-profit entity to hold URL-shortening databases in escrow, with the intent of continuing to resolve a member company's links should it get out of the business. At announcement, the 301Works organization has 21 URL-shortener members, including the largest, bit.ly. Many others are not (yet) on board. The members have agreed to cede control of their domain names to 301Works.org should they exit the field, and to back up their URL mappings regularly to the organization.

      "You'll never get rid of "link rot", only mitigate it. "

      It would be nice if we had some kind of weblike distributed permanent publishing system which was write-once and monotonic. Like Freenet, but without the obsessive secrecy (and child porn), and based on smaller chunks than 'pages'.

      Ie, every chunk of data is given a hash and put out onto the ... permaweb. Now it's out there, it won't change. Ever. But it can be cached aggressively (think huge caching servers on every continent, big ones on every network, one per host). These chunks could represent anything: files, emails, web forum comments, Twitter updates, blog posts/edits, Wiki edits, user identities, single value assignments for a single field - anything.

      Then to close the gap and make it a full-fledged Web-2.0y system, we'd need other chunks which can be interpreted as functions which aggregate chunks and create 'views' of them, and some way of defining relative rather than absolute names for chunks (such as 'now' and 'here' and 'this process/user/host/network'). And a way of a function-chunk subscribing to those 'relative' chunks so that it gets notified (and recalculates and notifies its subscribers) when they change. That part is a little tricky since it means defining a language.

      But even just with massive caching of permanent data, I think we could remove a lot of the suckiness from the current interwebs. We sort of broke the Web way back when we allowed cgi scripts and Javascript; now a web page isn't the primary unit, nor is it necessarily cacheable, nor does a URL represent an actual resource, just 'whatever that server wants to give you at that address now'. We have time-relative links, which are useful - but we should also have time-absolute links, which can be stored forever as long as anyone cares.

      We'd still be at the mercy of whoever chooses to cache (or not) - but permanent data chunks would be a lot more cache-friendly for those who cared to do themselves. Debacles like the End of Geocities wouldn't be nearly as big a deal - it would still be cached wherever anyone had accessed it.

      (This sort of idea of a precisely identified, perma-web rather than a 'whatever the heck the server wants to give you right now' web is pretty much what Ted Nelson's Xanadu was getting at, and has never really been implemented, at least not well.)

POST doesn't show up in URLs and is not bookmarkable. With GET you can get creative. For instance, langId sounds like a preference, which can be stored in a db for an authenticated user, whom you then hand a session ID. But you need a way for regular users to access that information with some degree of persistence as well. There's nothing sensitive about that URL and so in my mind it shouldn't require logging in.
