I suspected ZSCENEIDENTIFIER was a foreign key into one of these psi.sqlite tables. But looks like you're on to something connecting groups to assets. As for the UUID, I think there's two ints because each is 64-bits but UUIDs are 128-bits. Thus they need to be combined to get the 128 bit UUID. You might be able to use Apple's [NSUUID](https://developer.apple.com/documentation/foundation/nsuuid?language=objc), for example, by wrapping with pyObjC. Here's one [example](https://github.com/ronaldoussoren/pyobjc/blob/881c82a7ba90f193934b52b44143360c80dce5e5/pyobjc-framework-Cocoa/PyObjCTest/test_nsuuid.py) of using this in PyObjC's test suite. Interesting it's stored this way instead of a UUIDString as in Photos.sqlite. Perhaps it for faster indexing.
