- Web Linking (Common registry and the HTTP Link header):

http://tools.ietf.org/html/draft-nottingham-http-link-header-06

IETF Last-Call ended. A revision with registry clarifications is coming shortly.

- Well-Known URIs

http://tools.ietf.org/html/draft-nottingham-site-meta-03

IETF Last-Call ended. This was originally proposed as /site-meta but was replaced with the '/.well-known/' path prefix for HTTP and HTTPS URIs with a lightweight registry. A minor revision is coming shortly with adjustments to the registry structure per last-call feedback.

- Host-meta

http://tools.ietf.org/html/draft-hammer-hostmeta-04

An evolving draft. After site-meta was replaced with a common prefix for well-known URIs, host-meta was proposed as a common documents for protocols looking to avoid minting their own policy or metadata document. It is scoped for an entire host (per 3986, the entity controlling the hostname namespace across protocols). Host-meta uses the XRD schema (an OASIS XRI TC committee draft).

- LRDD

http://tools.ietf.org/html/draft-hammer-discovery-03

Complete rewrite pending. LRDD was initially proposed as a general purpose discovery mechanism for obtaining resource descriptors using links. The only new component in LRDD was the introduction of host-meta as a place to store templates for transforming resource URI into the URI of their descriptors. Since that entire section has now been moved to the host-meta specification, LRDD no longer offers any new elements other than listing useful link locations.

The next version of LRDD will move it into another direction, providing a more restrictive and specific flow using links for web protocols. Since all the building blocks are now defined elsewhere (namely host-meta and Web linking), LRDD can focus on a single simple profile that is sufficient for protocols such as WebFinger and OpenID.


Hope this helps.
