BTW, the monkey annoys me too.

I have updated the temp web site http://objectrepository.homepage.com/ with
1) a list of business requirements, and 2) placed the usecase.zip file with
the html pages showing what TMWG had started.  See appropriate links.

Business Requirements Note:
These are high level statements that a business person expects.  It is quite
often that the us technical people get confused with functional and
non-functional requirements.  Remember that the business seldomly
understands what we are talking about (scaleability, etc.) but just want
things to work NOW.

Some of these items are similar to the eCo Framework use of a registry,
which I believe is one of the most important architectures to date.  I
intend to lobby heavily in its favor.

Use Cases Note:
There are many users of the repository, people and application systems.  The
use cases depicts one and many different types of people that would use the
system.  This needs work.

Regards,

Scott

The output from Rose is converted into HTML and gif files.  It has a Java
applet for navigation.

We may want to start out with prose to begin with.  Unfortunately, I don't
think
we will find a common tool for us to all use (unless someone can pull some
strings
with Rational).  I have tried to read XMI, it is probably not the best
communication mechanism for humans.
