Videntity is an interesting web based social network that is open and combines OpenID, XFN, and FOAF. Users maintain an identity with personal information on the site, and they can invite friends to join. It is an open network because you can add information about people you know who are not in the network.

It outputs the social network data in FOAF and XFN, but does not yet read that in. The site is clearly a work in progress, but the creators seem to be on the right track with their future work described on the wiki. You can read more about that at
http://wiki.www.videntity.org/wiki/Social_Networking_Unlimited

You can find the actual network at http://videntity.org/.
