I put this on the standards track (as opposed to being experimental) primarily for the fact that it is currently being used in production environments. IBM and SixApart, for instance, have both deployed non-experimental applications that utilize the extension.
Experimental RFCs are for specifications that may be interesting, but for which it is unclear if there will be much interest in implementing them, or whether they will work once deployed. That is, a specification might solve a problem, but if it is not clear that many people think that the problem is important, or think that they will bother fixing the problem with the specification, the specification might be labeled an Experimental RFC. -- http://www.ietf.org/tao.html#anchor44 I believe that it's already clear that there is interest in implementing feed thread and that the spec will work. Regarding the bit about extensions needing be on the standards track because Atom is, I think that's wrong. There is a place for experimental RFC's, in fact, that's likely where things like the feed rank and person construct extensions are likely to initially end up. - James Julian Reschke wrote: > James M Snell schrieb: >> Just a general FYI.. >> >> The IESG has approved the Atom Threading Extensions (aka "feed thread") >> as a Proposed Standard making it the first standardized syndication >> extension.
