This can be passed from parent to child operator at design-time.
It is part of the input and output objects of OperatorGUINode#getOperatorStatus.
It is used to contain metadata about the IOBase objects that will be passed at runtime.
e.g.
For a dataset: what the TabularSchema will be, what data-source it will be stored on.
For a RowModel: what the input and output features will be, what the string identifier will be.
