Google announced today that it has begun indexing attribution of content to particular authors, not just to the websites they appear on. Links associated with the author of a page can now have the code rel=”author” added to them and Google will understand that to mean that the linked name is the linking page’s author. That’s a potentially significant change to the balance of power between sites and the individuals that create for them. Widespread adoption of rel=”author” in a web of open data could create a wide variety of other possibilities as well. There’s no reason to believe that Google will be the only company indexing this structured markup. That which is marked-up in a standardized, publicly and programmatically accessible way can be measured, monitored, optimized and more. Now the work, and the success, of particular authors will be trackable across publishing platforms and websites. There are a lot of future scenarios that could become real as a result of this. Imagine a famous author, for example, able to leave one of the great publications of the previous era and take their PageRank (or a future AuthorRank) with them. That could shake things up and that’s just one of many things that could be possible with the instrumentation of authorship.
