Resource Primary Key

Is there a way to define the row which is used as primary key on any given resource? In some cases, we aren't using

id

id

id

id as primary key and based on the API calls that the simple REST data source + AntDInferencer are firing off, the logic seems to assume that:

1)

name

name

name

name (the actual pk) is a related entity
2) A resource's pk will always be

id

id

id

id

What if for example, I have something like

placement.name

placement.name

placement.name

placement.name as the pk? Is this something that's currently supported? Any suggestions on how to approach this scenario?
