[Feature request] Add option to examine the nested objects in the Schema Editor

[flaneuse]

Describe the solution you'd like
In the Schema Editor, I can inherit properties from a pre-existing schema like the NIAID:Dataset. The interface is great for visualizing what properties to pull along from this schema; however, for properties that are objects themselves, those properties are hidden. For instance, creator has a bunch of properties associated with it, but I can't see what those are or edit them. I know things get complicated when you get to nearly infinite levels of nesting which are possible...
