The Videntity.org social network combines three recent web technologies: OpenID, XFN, and FOAF. OpenID allows people to login to a website using an identity from another website. FOAF provides an RDF/XML format for downloading profile and relationship data. XFN describes a standard set of relationships and a mechanism for embedding them into links in a web page.
