Again, however, Feed Rank is not intended to compete with the

I find this explanation most unconvincing. Near as I can tell, this
spec serves an identical purpose, but it's much less flexible.
In the Atom Syndication Format [RFC4287], the order of entries as
presented in a feed is typically considered to be insignificant. This
presents a challenge when the set of entries is intended to
represent an ordered or ranked list. This document specifies an
extension...
Seems to me it's pretty darn similar.
Your observation is correct. However, this only means that we need to
revise Feed Rank's introductory section to state its use applications
clearly. The second sentence of the introduction, which you
unfortunately dropped in your quote, should definitly mention the fact
that Feed Rank allows several, independent order relations to be defined
on the set of entries.
... This document specifies an extension that allows feed publishers
to establish numeric rankings for entries within a feed to be used as
a means of organizing and sorting those entries.
IMHO, the following would be an improvement on this, highlighting the
purpose Feed Rank is meant to serve:
This document specifies an extension that allows feed publishers to
establish one or more numeric rankings for entries within a feed,
each of which can be used, independently or in conjunction with the
others, to sort those entries according to different criteria.
But does this sound like an improvement to you, too?
