G'day.

The RFC labeling model is to assign a unique serial number to a static
document.  A new version of a spec gets a new serial number. This basic
model has the benefit of both simplicity and predictability.

To this we've added an overlay model, using Obsoletes/ObsoletedBy. This
makes it dramatically easier to see that something has been obsoleted and
to find its replacement.

However the seeing and the finding are an essentially manual process. One
must go to the online older document, then notice the Obsoleted By tag and
then click to follow it.

Sometimes it would be helpful for the requester to be able to say 'give me
the latest' more easily.

So I'm wondering whether the IETF should consider adding a citation feature
for this.

Something like:

     https://tools.ietf.org/html/rfc822/latest

would display the contents of:

     https://tools.ietf.org/html/rfc5322

by having the fetching system automatically traversing the Obsoleted By
links in RFC 822 and then RFC 2822.

Some sort of display banner would flag this, to help the user see that they
are getting a different version than they cited.


Thoughts?

It sounds good, for the most part, as a quick and dirty tool (though a 30x
redirect would probably be better than displaying the ultimate RFC
in-place.)

Out of malign curiosity, what would you expect from:
https://tools.ietf.org/html/rfc1738/latest
<https://tools.ietf.org/html/rfc822/latest> ?

Cheers
