W3C Technical Architecture Group recommends against XRI
I've previously noted my concerns about the introduction of the XRI into the OpenID 2.0 specification.
In a message to the W3C Technical Architecture Group list yesterday Tim Berners-Lee and Stuart Williams, co-chairs of the TAG, state categorically:
We are not satisfied that XRIs provide functionality not readily available from https: URIs. Accordingly the TAG recommends against taking the XRI specifications forward, or supporting the use of XRIs as identifiers in other specifications.
This statement leaves OpenID in an uncomfortable position, or so it seems to me. Much of the value proposition of OpenID lies in its simplicity and its close fit with the Web architecture - unfortunately, the introduction of XRI into version 2.0 of the spec did damage on both counts.
The statement from the TAG could hardly be clearer - I'm intrigued as to how OpenID people are going to respond.
