After importing from JDBC, I created view models atop each of the 3 imported models. I then created another view model wihch used the first set of models.

vParts <-- vPartsO, vPartsS, vPartsM

I created a series of folder into which I began to refactor the models. Source models refactored w/o issue. I refactored vParts and then received errors that the other models couldn't be found in vParts' new folder. (Unresolved reference "file:/home/pnittel/workspace-T71M1/HotMonday/View/Relational/vPartsM.xmi – in this case, it's still in HotMonday/)

The Message Log shows other errors, at least one of which had a stack trace. I'll attach the log
