Hi Stephen,
I have the feeling that you are using a 1.0.x version of CDO, right?
What you are describing sounds like what we call "external references" and
support for them has only been added to the 2.0 stream of CDO after
Ganymede:
213402: Support external references
https://bugs.eclipse.org/bugs/show_bug.cgi?id=213402
Btw. this feature was neither proposed nor developed by me.
For respective questions I really hope that Simon's new computer
will work wonders soon again ;-)
Simon, at some convenient occasion I need to know how this feature
impacts the existing IStores (if at all) and what I need to do in the
DBStore!
Cheers

Hello Eike,
Thank you for your quick reply. Yes, I am using 1.0 of CDO and I am talking about "external
references". For now, we are working without external references, but if we decide we really do
need them (and I expect we will), we'll move to 2.x.
Thanks again for your help!
Sincerely,
Stephen McCants
