Not too long ago Dan Connolly made a post called “FOAF and OpenID: two great tastes that taste great together“.
and I agree that FOAF and OpenID work well together. OpenID is technically a URI, an Identity of someone who is in a certain space.
Last week the OpenID people released the next version (2.0) of their specifications “OpenID Finally“.
OpenID 2.0 sees a few additions (made up of two components OpenID Authentication 2.0 and OpenID Attribute Exchange 1.0).
James Henstridge gives an in depth account of the differences in his blog post titled “OpenID 2.0“, with some additional information in his more recent post titled “OpenID 2.0 Specification Approved“.

For your knowledge OpenLink Software supports OpenID sign-up/login. With ODS you get a personal URI and an OpenID, same address
