They change over time, making it more complex to track down the correct version.

I'd preferr a stable loan application <=> rule set association. OTOH, it is probably *possible* to retrieve the correct snapshot version for a loan application if additional metadata is available. It's just more complicated: metadata needs to be available and sufficient to determine exactly *one* snapshot, snapshot needs to be available (not sure if Guvnor stores all snapshots forever or just a few).

For releases, there is *one* figure you need to know to reference a certain ruleset (the version number). Releases are normally kept forever. Or, at least in my environment, deleting releases is done with extra extra care -if at all-, whereas snapshots older than a week or so get removed automatically on a daily basis.

Best regards,

Ansgar
