LinkML JSON Schema Generator

[mahdanoura]

LinkML support composition terms like anyOf, allOf, etc.
The following snippet is how I model the security term as a class.

security:
       description: >-
         A Thing may define abstract security schemes, used to configure the secure access of (a set of) affordance(s).
       from_schema: td:definesSecurityScheme
       required: true
       exactly_one_of:
         - range: string
           multivalued: true
         - range: string

The following JSON Schema is generated from compositions:

"security": {
                    "description": "A Thing may define abstract security schemes, used to configure the secure access of (a set of) affordance(s).",
                    "oneOf": [
                        {
                            "items": {
                                "type": "string"
                            },
                            "type": "array"
                        },
                        {
                            "type": "string"
                        }
                    ],
                    "type": "string"
                }

The outer type in compositions are always translated to the type: "string". Sometimes we want a type Object in there. LinkML support the keyword: Any. But this will allow any object, which is not what we want in the json schema.

Btw combing oneOf with type is actually allowed but JSON Schema is used to factor out similar properties. I hope it helps.
