If the problem we are trying to solve is how developers decide which RFC to implement in this situation, perhaps all we need to do is make sure that the status conveys all the relevant information. The rfc-index file currently lists 821 as (Obsoletes RFC0788) (Obsoleted by RFC2821) (Also STD0010) (Status: STANDARD) while 5321 is listed as (Obsoletes RFC2821) (Updates RFC1123) (Status: DRAFT STANDARD) All the information is there, but you have to work to track it down. 821 is listed as obsoleted by 2821, which is listed as obsoleted by 5321. It's understandable if people miss the point, but the info is all there, so it's an information presentation issue. We just need to make it clearer. A simple way to do that would be to say that anything with a STANDARD or DRAFT STANDARD status should have that status clearly modified by any "Obsoleted" clause, which should point straight to the most current version. Thus, for 821, we might have: (Obsoletes RFC0788) ( (Also STD0010) (Status: STANDARD -- Obsoleted by RFC5321) I think most developers would have a hard time ignoring that phrasing, and it doesn't require any formal action to change the status of the older draft. -- Nathaniel On Jun 29, 2010, at 5:08 AM, Simon Josefsson wrote: > Phillip Hallam-Baker <hallam@xxxxxxxxx> writes: > >> The fact remains that RFC 821 has the STANDARD imprimatur and the better >> specification that was intended to replace it does not. >> >> It seems pretty basic to me that when you declare a document Obsolete it >> should lose its STANDARD status.
