Dona, I have the same questions as you do about what tools are apt. Before I comment for Jason's reply please note that I am new to ontology based systems, and I would be grateful if you can correct any errors.
Well...let me start will the fundamentals of rule-based programming in both Jess and CLIPS. Rule-based programming resembles event-based programming (like exceptions in Java). If we can program rules in Java or C++, then what is the need for Jess and Protege. What role does these tools play?
Today, I re-programmed my entire ontology in VC++ using MFC(event-based). The result is faster and highly portable ontology. So my question is - why not use C++ or any other well-established language?
If Jess aims to reduce complexity in coding, sorry to say, I dont think so.
OK ....let me compare CLIPS and Jess. Both have the same syntax...CLIPS can be portable to almost any language. Also, since it is built in C, the run-time is extremely fast comparing Jess. On the other hand, Jess depends on Java and Java programming alone for external interface.
CLIPS (developed by NASA) is well documented and been the language of AI systems for almost two decades. I learned Jess syntax from CLIPS documentation.
Maybe I am wrong about Jess, but with my current perspective, i dont see any good reasons to use Jess instead of CLIPS, C++, or even sole Java coding.
Please criticise.

Hi John, Jason,
this thread seems to go in different directions with issues that I'm
trying to sort out:
1. What is the best set of tools and languages for John. This requires
some more background information of what you are trying to achieve.

2. Combination of Jess / JessTab / Protege for John's specific example.
I'll stumbled across something when I played with John's example, so
I'll post that in a different mail.
3. Possible improvement of Jess / JessTab / Protege integration. This
is a more fundamental question, and this discussion should not be led
without Henrik Errikson, the developer of JessTab. While I'd be very
interested in learning more about the integration and its design.
However, given my current knowledge and experience, I wouldn't dare to
touch JessTab itself. I consider myself a user of Jess / JessTab /
Protege as a set of tools, and I'll gladly contribute my input from
that perspective.
Dona
