等效于 XML 模式 keyref 的 JSON 模式

Question

I am trying to create a JSON schema for data that looks like this:

{
  "equipments": {
    "A": {},
    "B": {}
  },
  "work": [
    {
      "equipment": "A"
    }
  ]
}

The schema I currently have is this:

{
  "$id": "example",
  "$schema": "https://json-schema.org/draft/2020-12/schema",
  "type": "object",
  "properties": {
    "equipments":{
      "type": "object",
      "additionalProperties": true
    },
    "work": {
      "type": "array",
      "items": {
        "type": "object",
        "properties": {
          "equipment": {
            "type": "string",
          }
        }
      }
    }
  }
}

In the equipments object different pieces of equipment are configured. These should then be referenced from items in the work array. In an XML schema I would do this with a keyref but I cannot find any equivalent for JSON schemas. Is there an equivalent or is this just not possible with JSON schemas?

It's not currently possible to validate relational data in JSON Schema.

There is a JSON Schema Vocabulary created to reference instance data , but I don't think that would do what you're looking for either.

There was an effort to define a Vocabulary for databases , but that has stalled.
