I searched and didn't find much. Feel free to redirect me if I have missed something.

btw, From my office, eclipsezone hangs indefinitely and has done so for the past many weeks. Go figure.

I am interested in the prospects of persisting EMF models into stores other that those provided thus far. Specifically, I am interested in RDF and Accumulo.

Is there any documentation on how one might begin with this?

I have seen persistence implementations done by the good people at eclipselabs for both mongo and rdf and following their approach, I did my own for accumulo. I would however like to spin up on the CDO way of doing things. It seems more robust and better suited to my upcoming needs.

Thanks

No, just examples of what other people have done.

Yes, CDO takes a completely different approach where the EObject's are
just facades for a communication link with a server and you use a
transactional approach to create and commit transaction.

Thanks Ed for the response. You mention examples of what others have done. Where might I find these? They were not apparent on the CDO pages.

Found the examples. They're in the source code.
