How to validate against a definition within a schema? about jsonschema HOT 3 CLOSED

Hi Chris,

Do you have an example of these messages, that would probably help in me answering the question.
Nonetheless jsonschema, like xmlschema, is about enforcing a strict format on your json.

So, it could be that different schemas are needed, but lets wait with that conclusion until I see some examples :)

Thanks for taking the time to reply.

I had wrongly given you the impression that I wanted to be lax about validation, whereas what I want is all the schemas to be in one file, with the appropriate schemas to be used by the appropriate parts of the application.

There are 3 types of JSON document in my application, each of which needs to validate against a different schema.

These three schemas share 90% of their definitions.

I would like to put these three schemas (and the definitions) in one .json file and validate each type of document against a specific schema from the file. I'm under the impression that a file can contain only one schema, so I wrote "definition from a schema" instead.

Currently I am trying three separate schema .json files and one .json file containing all the definitions, but this seems like an ugly solution.

Is this the only way to achieve the sharing of definition between schemas?

P.S. I'm not sure that "definitions" is a special word in JSON Schema, I'm just using it as per: "The entry schema - adding constraints" http://json-schema.org/example2.html

{
    "id": "http://some.site.somewhere/entry-schema#",
    "$schema": "http://json-schema.org/draft-04/schema#",
    "description": "schema for an fstab entry",
    "type": "object",
    "required": [ "storage" ],
    "properties": {
        "storage": {
            "type": "object",
            "oneOf": [
                { "$ref": "#/definitions/diskDevice" },
                { "$ref": "#/definitions/diskUUID" },
                { "$ref": "#/definitions/nfs" },
                { "$ref": "#/definitions/tmpfs" }
            ]
        }
    },
    "definitions": {
        "diskDevice": {},
        "diskUUID": {},
        "nfs": {},
        "tmpfs": {}
    }
}

I found what I needed in the API section for tv4 - does jsonschema do a similar thing?

tv4.addSchema() and tv4.getSchema(...#subschemas_id')
