A JSON Pointer is a specific property syntax used to reference the location of other JSON files. The property key for a JSON pointer is $ref and the value is a path relative to the base location which was specified by the id key.

Here’s an example of how the pointers destination is resolved:

1. The schema declares an id property:
2. “id”: “http://foo.bar/schemas/address.json”
3. There is a property defined with a JSON pointer as its value.
4. “some_property_name” : { "$ref": "person.json" }
5. When the pointers destination is resolved, it will be:
6. http://foo.bar/schemas/person.json
