Im using org.everit.json.schema for json schema validation in a spring boot application.
I have the following schema, that references a json schema on the same directory. The directory is the resources directory.. and am using everit to load it.
When i do this i get the following exception
java.net.MalformedURLException: no protocol: dataset.json
it seems everit cannot find the other document.. how can i get the validator to pull in other documents..
example of what im doing..
main.json
{
"$schema": "http://json-schema.org/draft-04/schema#",
"id": "test.json",
"title": "test",
"type": "object",
"description": "test.",
"properties": {
"data": {"$ref": "dataset.json"}
}
}
dataset.json
{
"type": "string",
"description": "The data ",
"enum": ["string", "integer"]
}
self referencing documents can be done by using ref: '[hash]'
also newtonSoft uses recursion well.'

Using MarkLogic version 10.0-4.2, I am trying to validate a simple JSON record against a simple JSON schema.
JSON Schema:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"properties": {
"SourceSystemName": {
"type": "string"
},
"BatchDtTm": {
"type": "string"
},
"SubjectArea": {
"type": "string"
},
"DocumentType": {
"type": "string"
},
"LastUpdatedDt": {
"type": "string"
},
"required": [
"SourceSystemName",
"BatchDtTm",
"SubjectArea",
"DocumentType",
"LastUpdatedDt",
]
}
}
Code being run in Query Console:
let jsonRecord = {"SourceSystemName":"ODH","BatchDtTm":"09/17/21 08:51:48:472723","SubjectArea":"Customer","DocumentType":"Preference","LastUpdatedDt":"09/17/21 03:59:53:629707"};
xdmp.jsonValidate(jsonRecord, cts.doc('/schemas/NewSchema.json').toString());
When I run the above code, I get error
XDMP-JSVALIDATEBADSCHEMA: Invalid schema "": ""
I'm not really sure what is 'invalid' about my schema. Can someone offer some insight into what MarkLogic is viewing as 'invalid'?
The second parameter for $schema is supposed to be the URI of the schema document.
$schema URI of the JSON schema to use for validation.
You are attempting to pass in the stringified content.
Try:
xdmp.jsonValidate(jsonRecord, '/schemas/NewSchema.json');
And ensure that the schema document is inserted into the Schemas database, not the content database.
I am looking for a way to generate random payloads in JSON based on the provided schema. Looking around I found something useful but with not a lot of github stars. LINK
Objective
To be able to validate multiple possible values for a field in the payload based on the schema provided.
Example
For schema -
{
"$schema": "http://json-schema.org/draft-04/schema#",
"type": "object",
"properties": {
"name": {
"type": "string"
}
},
"required": [
"name"
]
}
Possible payloads -
{
"name": "ABCDEFGHIJKLMNOPQRSTUVWXYZA"
}
{
"name": "ERTERER"
}
I hope my request for suggestion was clear.
I need to validate several JSON files against a schema in Golang.
I have been able to achieve it by using gojsonschema, that is really a straight forward library.
However, the problem I'm facing right now is that I have been given with schemas that have dependencies to another schemas and haven't found the way to load all the schemas that I need. Therefore, my validations always fail.
This is my main schema:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"$ref": "#/definitions/List",
"definitions": {
"List": {
"type": "array",
"items": {
"$ref": "#/definitions/Item"
}
},
"Item": {
"description": "An item ....",
"type": "object",
"additionalProperties": false,
"properties": {
"property01": {
"description": "The property01 code.",
"$ref": "./CommonTypes.json#/definitions/Type01Definition"
}
},
"required": [
"property01"
]
}
}
}
And, I have another one with common types:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"definitions": {
"Type01Definition": {
"description": "The definition for the type 01",
"type": "string",
"pattern": "^[A-Z0-9]{3}$"
}
}
}
Is there a way to load several schemas using that library? Or is there any other Golang library that allows to achieve that?
The way to refer to a file using $ref is to specify the absolute path of the file using a URL scheme. If you change the $ref to look like "$ref" : "file:///home/user/directory/CommonTypes.json#/definitions/Type01Definition, your example will work as expected.
If you need a bit more flexibility you can either try gojsonschema's NewReferenceLoaderFilesystem or switch to a different Golang library https://github.com/santhosh-tekuri/jsonschema. That library allows you to add custom resources so you can load several schemas at once.
I need a help regarding schema extraction by property.
For example i have a JSON schema:
{
"$schema": "http://json-schema.org/draft-04/schema#",
"description": "A simple address format",
"type": "object",
"properties": {
"street-name": { "type": "string" },
"locality":{ "type": "string" },
"region": { "type": "string" },
"postal-code": { "type": "int" },
"country-name": { "type": "string"}
},
"required": ["locality", "region", "country-name"]
}
I have an use case, where i need to extract the schema corresponding to each property and send to another service, where it will do validation against the value and save in database. Here is the sample object i need to send to another service.
{
"propertyName": "street-name",
"value": "19, Canton street",
**"schema": { "type": "string" }**
}
The questions is,
how we extract the schema for a particular property from a give JSON schema??
Given the property path, Is there any nodejs module exists to do this schema extraction? or if there is any other solutions exists ?
Because this is very simple scenario, but if we have array, anyOf, OneOf type its getting complicated;
Thanks in advance ! Please let me know if the question is not clear !

I have searched SO and JSON schema documentation for a few days now, but I'm struggling to get my JSON Schema references to work across multiple files in the same directory.
My root schema would be an oneOf object:
{
"$schema": "http://json-schema.org/draft-04/schema",
"id": "http://localhost/json-editor/schema/function.json",
"title": "Function",
"oneOf": [
{
"$ref": "./fn_md5.json"
},
{
"$ref": "fn_sha1.json"
}
]
}
Now after reading the docs and most questions here, I'd assume both ./fn_md5.json and fn_sha1.json would be resolved to http://localhost/json-editor/schema/fn_....json (where the ... represents their respective name, of course). However, the resolver keeps looking into http://localhost/json-editor/fn_....json, which appears to be relative to the application's url (JDorn's JSON Editor running at my http://localhost/json-editor/).
Am I understanding the schema and id wrong, or could it be an error with the editor's URL resolver?
Thanks!
for find the relative references you need use $id like this:
{
"$schema": "http://json-schema.org/draft-04/schema",
"id": "http://localhost/json-editor/schema/function.json",
"$id":"https://www.baseurl.com/"
"title": "Function",
"oneOf": [
{
"$id": "./fn_md5.json"
},
{
"$id": "fn_sha1.json"
}
]
}
