    In their AAAI88 tutorial, Bobrow and Kiczales refer to an example they
    used which "[would] sketch how CLOS can be connected to a persistent
    object system".

    Alas, I was unable to attend, and the course notes do not mention such
    a topic.

    Although I have a couple of ideas on the subject, I'm new to CLOS and
    would prefer to benefit from the experiences of those who have gone
    before. Does anyone have any ideas, papers, ongoing research, and/or
    code implementing any such mechanisms? If so, would they be so kind as
    to share them?

    I know of only one commercial implementation of such an idea (Mercury, AI
    Technology), although various ES shells (KeeConnection, Nexpert, ART "real
    soon now") have similar (albeit crude) mechanisms for mirroring "objects"
    in their proprietary representation language into SQL DBMS tables.

    Thank you.

Another view showing how to connect an object model to a persistent
store using CLOS is described is in the paper:

 Andreas Paepcke, "PCLOS:  A Critical Review", ACM OOPSLA Conference,
1989 p221-237. 

 You will also find other CLOS papers of interest in that
conference.
