Overview
This topic discusses the JSON representation of Schematic Diagram Content objects.
A Schematic Diagram Content object is returned with the following properties:
name: The diagram nameextent: The diagram extent (envelope)layers: An array of layer objects that compose the schematic diagramroot: Optional; An array of schematic feature identifiers (Long) that identify schematic root nodes in the diagram.Nodes end: Optional; An array of schematic feature identifiers (Long) that identify schematic end nodes in the diagram.Nodes

}Layer object definition
Each layer item in the layers array corresponds to a schematic feature class associated with the diagram template on which the diagram is based.
All the schematic feature classes that are associated with the diagram template are detailed in this layers array, including those for which no schematic features are contained in the diagram.
