I wish we had suitable tools that meet those requirements:    (02)

I mostly agree with the comments by Leo and Pat.    (04)

CycL is the richest of all the KR languages, and it could express
anything that any of the others can support.  But the Cyc tools weren't
designed to support "context driven rule-sets and dynamic decision
making based on computational intelligence agents."    (06)

It would be possible to express any of the ontology and KR information
in Cyc, but there would be some serious questions about how the Cyc
tools could be integrated with intelligent agents.  In fact, that same
question comes up with any or all of the KR languages on the list.    (07)

OWL cannot begin to satisfy the requirements on Duane's list.  It
wasn't designed to handle agents or rules, much less "context driven
rule sets" or "dynamic decision making".    (09)

I'm sure that tools that meet the requirements listed above will be
available within the next 5 years or so, but I don't know of COTS
(Commercial Off-The-Shelf) software that can support them today.    (010)

My recommendation is to use FactGuru (open source) to manage the
English definitions of all the terminology.  FG will also store
and manage the formal definitions in any notation(s) that are
used for the implementation.  I don't believe that there is
any single ideal notation that is available as COTS today.    (011)
