You have lost me here.  Even if you created a bi-directional relationship, why
would "Meg Ryan" have any more-or-less involvement?  I think you are adding
your own semantic interpretation to omni-directional vs. bi-directional links,
and that is what is creating the issue.  What you actually need to do is track
who created an assertion, so that they are responsible for managing it.  You
could do this via topic map scopes, since they can be used to define from whose
point of view an association is made.  At the moment, you are running with the
idea that the source of a omni-directional association can also be construed as
the creator.  I cannot help but wonder if that assumption might not let you
down at some stage.

	Cheers,
		Tony.
