Properties in Model.json - node.js

Question

What are the properties that can be mentioned in the Model.json file of a model in loopback(Strongloop) ?
I was trying to figure out what extra properties can be added to the model.json file but in the documentation very less is given.

Answer 1

Certain new fields like – hidden, hiddenProperties, hiddenAPIProperties can be added to the model.json file which are not mentioned in the Loopback documentation……take a look at these
