Native JSON schema support

HCL Link supports using JSON templates, or JSON schema documents to define the schema of a card.

. A JSON template is an example document containing the JSON that defines the data for the card. A JSON Schema document is a specification complying to the JSON Schema specification.

See the JSON Schema website for schemas.

A schema defined by a JSON template of JSON Schema document is created by importing the JSON by clicking on Schemas > XSD/JSON. This function uploads the JSON file and produces a schema that can be used in an input or output card. The associated JSON Schema properties are added when you specify a native JSON schema in the Schema property on an input or output card. These are Fixed Order and Unknown Elements.
