[protege-owl] Rules to modify/create ontologies from ontologies?

Since I got no answer yet I will broaden my question:
what ways exist to systematically change or merge
the knowledge in one or more ontologies into
a new ontology?
Is the only way to do this to hand-code it or
do tool or more formal, e.g. rule-based, approaches
I'd highly apreciate any feedback about this, even
if it is not a solution -- I'd also apreciate hearing
from people who face similar problems.
