[x3d-public] ChatGPT —run this prompt

[John Carlson]

Produce Java code that creates a mapping from the input X3D unified object
model ConcreteNodes to JSON subschema objects, using Java to generate JSON.
Put “@“ in front of SF-prefixed field type property name and “-“ in front
of MF-prefixed field type property name. Don’t forget to use a XML StAX
parser and a loop to go through all ConcreteNodes.
