APML allows you to share your own personal Attention Profile in much the same way that OPML allows the exchange of reading lists between News Readers. The idea is to compress all forms of Attention Data into a portable file format containing a description of your ranked interests.

Attention profile sources
Though not an exhaustive list, your attention profile could be based on:

• pages you bookmark and tags you assign
• your favorite videos, music and TV shows
• hyperlinks you follow and share with your friends
• things you write about and topics you keep track of
• items you click on in your feed reader
• things you buy from a web store
• places you visit and events you attend
