Hi MindSet, I'm sorry but I'm not already familiar with OLE DB and so it would take too much time to research it and figure out how to work with it.

Each object in MoI is already assigned a unique UUID though, and it is accessible to script by the .id property which returns it as a string.

Maybe the OpenNURBS library would be useful to you, it's available from https://www.rhino3d.com/opennurbs , using that library you could open .3dm files saved by MoI and access the objects with their UUIDs from your own program.
