- Yes, most of us here use the Notes interface, which maintains such threads
- or "notes strings" as part of its database. The current NNTP news servers are
- much too dumb for this - it takes far too many messages for the client to
- work out the threads. You can do it, but it is painfully slow if your
- NNTP server is on a remote machine.

- Yes, I too have been thinking along these lines. The first step is an "agent"
- program which runs daily to get the complete list of news groups, sorts them
- alphabetically then builds them into a small group of html docs that allow
- users to browse the newsgroup names hierarchically. The next step is to
- extend the agent to build an html doc for each newsgroup's index. This
- involves getting the headers for any new articles in that newsgroup and
- can be linked to the job of tracking backward references, and updating a
- database of threads/notes strings.
-
- In the longer term, we can lobby for such support to be added into future
- releases of the NNTP daemon. Our only hope in the short term is to build
- agent processes that do the additional processing as a regular background
- activity. You can think of these as a variety of "knowbots" which carry out
- tasks that are impractical to perform on an interactive basis.
-
- I am sure NEWS is due for a shakeup what with the arrival of MIME and html as
- a registered format. The current restrictions on character sets and plain
- text is rather cramping these days. Furthermore the number of newsgroups has
- grown enormously over the last few years - the ability to carry popular
- groups locally and to get the others on request from remote servers seems
- long overdue.

-
- I have been toying with an extension to the URL syntax for just this purpose:
-
- news://news.ysu.edu/alt.culture.*
-
- This implies the list of newsgroups under alt.culture on the NNTP server
- "news.ysu.edu".
-
- news://news.ysu.edu/alt.culture.usenet
-
- This example specifies the newsgroup "alt.culture.usenet" as held on the
- nntp server "news.ysu.edu"
-
- news://news.ysu.edu/<C34u1w.7Ls@news.ysu.edu>
-
- This specifies an actual news article from that newsgroup and server.
-
- One outstanding problem is which machines archive what newsgroups? It is
- often the case that the original article has been discarded from the local
- server, and it would be really great if the browser could then try to get the
- missing article from a remote archive system. The establishment of well known
- servers for given groups would be a good start.
