Hey Alan,
Just to keep you updated, it appears from the beta notes that OCUM 6.1 will fix the snapshot issue in 6.0. Am trying to get a hold of it to test this out now.
From the 5.2 point of view, I've included a dictionary entry and cache query that should work for OCUM 5.2. They are based on the 7-mode snapshot model, database format appears the same. Let me know if it works, unfortunately I can't seem to get any storage controllers registering to my OCUM 5.2 instance to test it out.
You'd also need to add a finder but that should be simpler if the object type and cache query is there.
cheers,
- Michael.
