The JSON built-in filter doesnt have enough documentation about JSON Path. Is JSON Path a well defined standard? How much of it is implemented in Studio? Could you please give typical examples on how to do things. The video at https://www.sdltrados.com/video/how-to-json-files/148866/ is a start, but it really doesn't go very far. Can I translate everything except XYZ? Can I translate if something is the child of something else. Etc...
I think JSON Path is less well known than XPath and a good explanation from SDL would be very useful.
