- Hello all,
-
- It is true that the nntp working group has been pushing against all
- sorts of retrieval issues. How any of the following would be
- implemented is completely an open question, right now. I should say
- that much of what follows was the result of informal brainstorming,
- and a lot of discussion at various USENIXes. I think everyone agrees
- that the NNTP people do not yet have enough information to make a
- decision, and there is a growing concern about scope of whatever
- project we would choose to take on, as one could quickly envision a
- very broad all-encompassing project that would serve everyone's needs
- but never be implemented. As we begin to discuss best ways to present
- news to the user, we immediately come up against five questions.
- Briefly described, they are the following:
-
- [1] How shall the user select and receive new information?
- Are we talking SQL or Z.39 or what?
-
- [2] Should the mechanism be a pull-update/lockstep mechanism, as
- it is now, or does the server need to have enough smarts about
- things like priorities such that the mechanism should be
- async/interrupt driven?
-
- [3] Should we be writing the protocol with some sort of RPC
- mechanism in mind, such that the application doesn't even know
- if the service is local?
-
- [4] How do we handle archives? Should a saved article be treated
- just as any other article, or do we need stronger archive
- search mechanisms in NNTP? OR, should archive support be
- placed in the netnews model, itself (e.g., sendme style
- retrieval)?
- OR, should netnews reading become a distributed model, as
- access to the Internet approaches ubiquity? Here is where
- we begin to delve into resource and information location
- issues.
-
- [5] Should whatever mechanism we design be limited to netnews, or
- should we also leave enough rope for someone to use it for
- mail?
-
- So what we have right now is a growing list of questions, and not very
- many answers - YET.
-
- I must clarify one point Tim made. News is currently stored and read
- locally mostly for historical reasons. The plain fact of the matter
- is that netnews has been and continues to be more popular than the
- Internet, simply because it costs less. Thus in past people have not
- considered reading over the Internet as ``the mechanism'' because it
- could not be used as such by a large portion of the participants.
- There is also an issue of how to find new and interesting articles
- under a distributed model. That's an area I haven't given much
- thought at all to.
-
- The statement that the current NNTP is nothing more than a file
- transfer protocol is largely correct. It's a specialized version that
- takes advantage of the netnews architecture. In fact, it would have
- been quite possible to implement NNTP *in* FTP as an extension.
