Hi Bill, Cory, Leo, Azmat & all:    (01)

I support Leo's goal statement. A pretty good rule of thumb I frequently 
use and picked up from Robert Kent's Information Flow Framework is 
Languages, Logics, Models and Theories. IFF calls this an environment, 
but we could call these dimensions.    (03)

Anyway, most folks here know I'm a fan and I've added the following 
comment in the appropriate place on the wiki:    (04)

The draft above looks like a good start, but there's been some great 
framework work available that we can leverage. Some folks here are 
already familiar with the Information Flow Framework. For those who are 
not, IFF is a descriptive category meta theory that uses category 
theory, information flow and formal concept analysis. Highlights include 
Goguen's Theory of Institutions as well as Sowa's Lattice of Theories. 
See below for reference to the ongoing work on IFF. 
http://suo.ieee.org/IFF/    (05)

For those who haven't had the opportunity, there's a lot of great work 
there and I highly recommend it !    (06)
