Wow! That's quite a set of criteria, and looks almost nothing at all like
my criteria, which are more like:
* over 20,000 document fragments, ranging in length from 1 to 100,000
characters, all with some metadata, which will remain on the system in
mostly stable form.
* about 5 simultaneous authors, up to maybe a thousand people reading the
* indexing and searching moving around in the background.
Given these wildly different criteria (and I'm sure others out there have
different ideas as well), the concept of a database for XML seems pretty
weird. Maybe we should focus on tools for getting information into and out
of a repository, and let vendors create different back ends created to
match our widely differing needs. That way we can still share tools, and
read each other's material, but aren't locked into a particular vendor
whose approach won't work for everyone.
