Take a look at archetypes on Plone.org, and download a version from sf.net.
Look in particular at the ReferenceEngine, based on the catalog, and note that there have been implementation changes, and there's a new beta version.
Ben Saller and Kapil Thangavelu were part of the team responsible for Archetypes.
Um, this seems something more what I'm looking for. I can see that ReferenceEngine and Referenceable implements some referential at object level. I was thinking about to do it at catalog level, maintaining a paralelism with a referential model, where catalog = table. But making an implementation like Archetypes one is another good option, of course.
Thanks for the info
