There is now a new open standard called APML (Attention Profiling Markup Langauge) for storing your personal Attention Profile – effectively a list of your ranked interests. Think of it as a Tagcloud in XML.

We are starting to see early adopters like Emily Chang and Ian Forrester creating a living APML file from their Lifestream and promoting it on their blog sidebar like they would their RSS feed. You can see Emily’s linked from the right side of her About page here: http://emilychang.com/go/about (this one happens to be created by our Profiler service at http://www.engagd.com).

APML has all sorts of implications for creating an open Attention Economy where users are in control and can move from one ‘Attention Aware’ application to another – taking with them a personalized internet experience.
