Scott Robbin has released TinyFinder, a rev=canonical JetPack Widget:
This weekend, I started to play around with Jetpack from Mozilla Labs. [...] The widget that I created–TinyFinder–looks for rev=canonical links in a webpage, and displays them in the statusbar of the browser window. Rev=canonical links are meta tags that are used when a website wants to suggest a preferred tiny url to use. [...] Several services are starting to employ their own custom tiny urls: Dopplr, Threadless, Songza, and many more. – Scott Robin
A plugin for Ubiquity that “uses the RevCanonical API to check and see if the link provided has published a shortened version of the given page using a HTML link element with rev=”canonical”. Check it out
lnkd.in is a URL shortening services from Dave Marshall that “uses the revcanonical API to return friendly short URLs whenever possible”, or it falls back to traditional shortening techniques. And it’s open source.
Sam Pullara has an example of how to use YQL to grab rev=canonical links.
sites could use YQL to grab the #revcanonical links. we shouldn’t have any problem scaling to do this: http://bit.ly/ZHRgO #yql – Sam Pullara
Jeff Jones with a modest proposal
My suggestion for the whole #revcanonical #shortlink problem is a new HTTP method: GETSHORTY! – Jeff Jones
Mike Migurski has coded up the simplest possible self hosted URL shortener, and published it on github
One of the small tools that I think would make rev=canonical even more useful is a rapid, brainless way to create short URLs for any domain. It’s possible, in a brief PHP script that only knows how to speak HTTP, to:
- Redirect from short URLs to long URLs
- Respond with a short URL for a given long URL
- Add a new short URL for a given long URL
Jeremy rounds up a few of the recent rev=canonical implementers as a spring board for a great discussion about a “whole bunch of nice metacrapital things you can do with your visible hyperlinks”, and adoption patterns:
The rev=”canonical” convention makes a nice addition to the stable of nice semantic richness that can be added to particular flavours of hyperlinks. But it isn’t without its critics. [...] The unbelievable speed of adoption of rev=”canonical” shows that it fulfills a real need. – Jeremy Keith
