<div class="moz-cite-prefix">An update to my problem:<br>
<br>
As per Davide's instructions, I tried with the 5.5.1-SNAPSHOT and
the problem went away. So I guess the strange behavior was due to
some unfixed bug in 5.5.0.<br>
<br>
Thanks Davide for the kind help.<br>

<div class="moz-cite-prefix">Correct me if I'm wrong, I would
summarize your requirements as follows:<br>
- you need some "A-box" reasoning, but you are fine with a
rule-based approach<br>
- the object-oriented integration Drools provides is quite
convenient<br>
- you have large data sets for which an opportunistic,
"query-oriented" approach<br>
would work better rather than a fully generative "forward
chaining" approach<br>
<br>
Drools "hybrid-chaining" approach could be very useful here -
I'm not sure how<br>
well documented it is, and how you are planning to use it, but
it would be interesting<br>
to see one of your rules - even "stripped" of the details you
don't want to show -<br>
to discuss the behaviour of the engine and its implications.<br>
<br>
I had a use case apparently very similar to yours some time
ago.. I'm working even<br>
now on some experimental forms of rule/object/ontology
integration. The "trait"<br>
feature might be an alternative to the explicit addition of
classes to objects .. it was<br>
enhanced a few days ago to support updates and modifications. <br>
If you have an ontology to begin with, you might also be
interested in the ontology -> class<br>
conversion tool I'm working on even now<br>
