Cannot find classification schema reference in JSON Schema - jsonschema

Question

I have a product schema which tries to reference an id in my document. It is a common reference to multiple objects. Unfortunately, my ide claims classification reference cannot be found. I am very new to json schemas and find only snippets which don't quite show how the references are supposed to work. Here is my schema.
{
"$schema": "https://json-schema.org/draft-07/schema#",
"$id": "https://digital.com/schemas/products",
"description": "Schema for Product Data",
"title": "Products",
"type": "object",
"required": ["products"],
"properties": {
"products": {
"type": "array"
},
"options": {
"type": "array",
"items": {
"type": "object",
"properties": {
"productId": {
"type": "string"
},
"productName": {
"type": "string"
},
"categories": {
"type": "object",
"additionalProperties": false,
"allOf": [
{ "$ref":"/products/classification" }
]
},
"productType": {
"type": "string",
"enum": ["electronic", "digital", "internet", "video"]
}
},
"required": ["productId"]
}
},
"classification": {
"$id": "/products/classification",
"type":"object",
"properties": {
"relevance-score": {
"type":"integer",
"minimum": 1,
"maximum": 5
},
"group":{
"enum":["adult","teen","seniors"]
}
}
},
"definitions": {
"mp4": {
"type": "object",
"properties": {
"mediaType": {
"type": "string",
"enum": ["video"]
},
"playlength": {
"type": "integer"
}
}
}
},
"mp3": {
"type": "object",
"properties": {
"mediaType": {
"enum": ["audio"]
}
}
}
}
}
I have defined a classification object to use in the class property of categories object like this
"$id":"/products/classification".
I tried setting it relative to the $id at the top of the document which is "https://digital.com/schemas/products" but I'm sure I haven't set it correctly. I want to use the classification object in the allOf property of the categories object.

Answer 1

Your reference is "$ref": "/products/classification". Where is this supposed to point?
Odds are the validator you're using is looking for a schema with the $id of "https://digital.com/products/classification". If the validator doesn't know about this schema (or perhaps is searching for that file), it can't get to it.
The other possibility is that you intend this to be a JSON Pointer. If that's the case, it needs to be URI-formatted: "#/products/classification"
However, this location doesn't existin within your schema, so it'll need to be updated.
