I agree that query should be addressed separately from rules (and
I'm not convinced that we're ready to begin the standardization
process for rules just yet, but that's another discussion entirely...)

I consider this far too coarse grained to be efficient and generally 
useful
(note the important qualification 'generally').

A given model might be *huge*. GETting and PUTting entire models seems
to me to be a corner case, and not what most folks really need/want to 
do.

Let's please separate issues relating to knowledge management from
those relating to knowledge discovery. What the SW needs acutely, IMO,
is a lightweight, efficient, intuitive and easy to implement solution
for knowledge discovery.
