It's the BigDeal Part I. The BigDeal Part II is the integrated editing
tool, which is much farther down the line, unfortunately.

One of the up-front requirements is that the viewing engine will support
all kinds of output, although the system that we build will initially
This is an important, up-front design requirement. The viewing engine
does have to be extensible in this way. The solution that Doug seems to
like is IBM's WBI. WBI is not open source right now, and as I mentioned
on Thursday, I'm concerned that it may be difficult to convince IBM to
make it so, although Doug disagrees with me on this. It would be helpful
if someone took a look at it and did a good evaluation on how well it fits
our needs. If it is indeed the best tool for our job, then we need to
start negotiating with Jim Spohrer about making it open source so that we
can use it.

should make sure it works in IE and Netscape. And because our viewing
engine will easily deal with any type of output, Lynx lovers like myself
will be able to easily write their own views for the system.

XHTML, which should work with existing browsers for the most part. My
thinking on stylesheets is that we should support XSLT on the server side
-- in other words, for now, let the viewing engine deal with styles rather
than rely on the clients. Getting CSS to work on both IE and Netscape can
be a real pain, especially if you're trying to do funky things. However,
I wouldn't be opposed to using CSS in our system if it helps us do what we
want to do.

Very good question. From previous discussions, people seem to like a
servlets/JSP solution, and I think there are strong arguments for doing it
this way. However, I also believe strongly that the initial rev of what
we write should be thrown away fairly quickly, which would bode well for a
Perl/mod_perl or Python/Zope-based solution. Doing it this way would
allow us to develop things quickly, and would give us the option either to
stick with a particular language or to move to a different system
entirely. Heck, maybe we'll decide that C++ is the best language for our
needs at that point. Doubt it, but maybe.

I've got some initial stuff that we worked out at previous meetings. I
promise, I'll get them up on the web before the weekend is over.

We don't have anything worked out at the level of 4a-4c; that's something
that needs to be done. I have some thoughts on these that I'll share
when we reach that point.

We've worked out some initial views, which I'm also due to post. Within
the next two days, I promise.

Very good question. Perhaps not for V1, but very soon after that; we'll
need it to support the Reply-From-Browser feature. We should probably
build it in from the ground up, because we will definitely need it, and
we'll be able to do some cool views with it, such as maintaining a
personal "e-mails read" database for each user, similar to .newsrc files.

Nope. Getting as much Augment stuff as possible available is definitely
on our To-Do list. Shinya and Grant are working with Doug on pieces of
this, and Joe has made some very good suggestions regarding this as well.

As I mentioned earlier, keeping track of e-mails viewed.
