It is no different, the intent is exactly the same as if the reply
were made in the "comments" of the hosted entry (presuming it hosted
comments). An entry with a "parent" or "in-reply-to" should be
threaded among other siblings of the replied-to entry or comment.
"parent" or "in-reply-to" is not merely a dc:relation, dc:references,
html:cite, or annotea-ns:annotation, it is a response directed
specifically to a previous entry or comment, as if in a conversation
The "single hosted" use case allows comment feeds to be collapsed to
one main comments feed, or even one single main feed. The distributed
use case strictly parallels the single hosted case.
The In-Reply-To of email and References of email and UseNet are the
semantics being modeled. Variously, In-Reply-To and References have
been used (abused) as an M:N relation, but practically have only
interoperated as a 1:N relation.
Annotea has a similar model. Annotea distinguishes an annotation
as being an open annotation or comment on a resource (an "annotation",
similar to dc:references or html:cite, even if it is a principle
citation) and a "Reply", in reply to a resource or another Reply.
"atom:parent" and "atom:in-reply-to" have the same semantic as
It is only *because* the relation is the same as from single-hosted
comment thread that the relation is useful. A single-hosted comment
thread, in current practice, can either be flat (all comments reply to
the "main post") or threaded (comments can reply to other comments).
Distributed comments are the latter, by their nature.
