I also refer to the manual config documentation, which gives me the details on the specific tables/feature class, along with their field models and object models etc.

I'm not 100% sure on the Gas, Water and Power model names as I'm not using them at the moment... But this looks like it may be of some use? ArcFM Desktop Configuration Guide
We have GDBREPLICATION and MULTISPEAKEAEXPORT export assigned... Multispeak export was deprecated before I got here, and replication died during our 10.2.1 upgrade. I was looking for documentation on these specifically, since they are assigned to many feature classes. Those being absent from the documentation, and probably me looking for class model names where field model names are stored may have blown this out of proportion.
