The way AdaptableStorage currently deals with OIDs is convoluted. 
Explaining it would be hard.  The problem itself isn't complex, but 
AdaptableStorage's solution is.  It's often harder to write a simple 
solution than a complicated one.

Hopefully, it will make it easy to write serialization components and 
the components will be useful enough that many kinds of applications can 
use them.
