FOAF [1] stands for friend-of-a-friend. It’s a semantic-web format for describing people and the relationships between them.
Putting FOAF on your site is easy:
1.Generate a FOAF description. You can quickly generate a basic FOAF file by using the FOAF generator at FOAF-a-matic [2].
2.Put the FOAF description on your web server. Save it in your root web directory in a file called foaf.rdf
3.Add an auto-discover link to your website template. Put the following in the <head> of you template.
<link rel="meta" type="application/rdf+xml" title="FOAF" href="/foaf.rdf" />4.Install the Semantic Radar [3] plugin for firefox. This will tell you when you are at another site that has FOAF data and let you view it.
