Status of this Memo
By submitting this Internet-Draft, I certify that any applicable
patent or other IPR claims of which I am aware have been
disclosed, and any of which I become aware will be disclosed, in
accordance with RFC 3668.
Internet-Drafts are working documents of the Internet Engineering
Task Force (IETF), its areas, and its working groups. Note that
other groups may also distribute working documents as Internet-
Drafts.
Internet-Drafts are draft documents valid for a maximum of six
months and may be updated, replaced, or obsoleted by other
documents at any time. It is inappropriate to use Internet-Drafts
as reference material or to cite them other than as "work in
progress."

Abstract
This Draft, together with its companion draft [USEFOR], are
intended as standards track documents, together obsoleting RFC
1036, which itself dates from 1987.
This Standard defines the architecture of Netnews systems and
specifies the requirements to be met by software which originates,
distributes, stores and displays Netnews articles.
Since the 1980s, Usenet has grown explosively, and many Internet and
non-Internet sites now participate. In addition, the Netnews
technology is now in widespread use for other purposes.
Backward compatibility has been a major goal of this endeavour, but
where this standard and earlier documents or practices conflict, this
standard should be followed. In most such cases, current practice is
already compatible with these changes.
A companion Current Best Practice document [USEAGE], addressing
requirements which are present for Social rather than Normative
reasons is in preparation.
[The use of the words "this standard" within this document when
referring to itself does not imply that this draft yet has pretensions
to be a standard, but rather indicates what will become the case if and
when it is accepted as an RFC with the status of a proposed or draft
standard.]
[Remarks enclosed in square brackets and aligned with the left margin,
such as this one, are not part of this draft, but are editorial notes to
explain matters amongst ourselves, or to point out alternatives, or to
assist the RFC Editor.]
[In this draft, references to [NNTP] are to be replaced by references to
the RFC arising from the series of drafts draft-ietf-nntpext-base-*.txt,
which has now passed its IETF last call.]

[This draft [USEPRO] and its partner [USEFOR] are an interim stage in
the splitting into two parts of the earlier draft [ARTICLE]. There is a
certain amount of material - basic concepts, definitions, etc - which
ultimately need occur in only one of the documents, and further such
material which may not be needed at all (e.g. terms currently defined
which in the event may not get used). For the moment, all such material
has been retained in the present draft (it being, in any case, easier to
take unwanted stuff out than to put new stuff in). It has also to be
decided, for such material which is needed by both documents, which one
(the "Primary") should contain it and which one should incorporate it by
reference (essentially, this draft is written so that it could be the
Primary).]
[Again, references in this document to sections which ultimately are
expected to be in [USEFOR] are still to the old sections in [ARTICLE],
since [USEFOR] is not stabilized enough to refer to specific sections in
it yet. These references can be recognized by being prefixed with "a-".
These references can be fixed up later as we find the proper places for
them to point to. In any case, there will doubtless be more toing and
froing of texts between the two documents before we are done.]
