FOAF as part of a reputation system

I learned about FOAF some time ago. An XML-based personal profile that you host on your own site, it sounded kinda neat, but there didn't seem to be any cool applications for it (none that I found, at least). Until now. Enter David Sifry and Technorati. Technorati has implemented a Profile feature that utilizes FOAF. This profile information is intergrated into Cosmos listings, displaying the bloggers photo next to the person's blog, with a link to the Technorati profile. Cool. So this morning I set up my FOAF, using the FOAF-A-Matic, and my Technorati profile can be found here. The profiles don't display much information yet, but I have a feeling more blog and blogger information will be added in the future.

This got me thinking about a potential role of FOAF in online reputation systems. I had thought about this before, but I dismissed it because self-hosting your own reputation statistics would not result in enough trust (because it could be easily altered). But the Technorati implementation takes basic profile information from the FOAF file and combines it with linking information from many other sources (blogs). The result is a trusted authority (Technorati) combining profile (FOAF) and reputation (links) information from a wide array of sources to form a picture of person's reputation. All of the data used to create the reputation measurement is stored in a distributed manner, on many different web servers, controlled by many different people. I think this reputation system model has potential.

By the way, I learned about this new Technorati feature via Marc Canter. For more FOAF information, read Marc's recent posts on the subject: Here we go!, Easy FOAF Notes, Friends of FOAF, and Getting FOAFy wit it.
