I have already created my own schema on intellij environment, and it's working good, but still have problems in auto completion which provides intellij to the schema,
for example if object "car" defined in json schema then intellij can recognize that there's such object in the schema and intellij will give it as suggestion through out coding json, the problem that I'm facing is that the suggestions are contains all the objects that defined in the schema, but the expectations are to get the objects which defined under the scoop of another object
This is some code of my own schema:

}
}
},
"required": [

}
}
So what I expected is, when the type of object determined to "setValuesComp", the auto completion will suggest the relevant properties, that's mean it will not suggest "in" property which is belong to "invokeWebServicesComp" not "setValuesComponent".this picture show the auto complete problem in my real environment
Your JSON schema seems to be invalid. The below JSON content should be present inside object type.
"properties": {
"pipes": {
"description": "section which defines the mandatory pipes object in the file",
"type": "object",
"patternProperties": {
".{1,}": {
"$ref": "#/definitions/Pipe"
}
}
}
},
"required": [
"pipes"
]
In your schema, it is present as part of the "definitions". Please make this correction and then check if you are able to get the suggestions.

I am attempting to validate the following JSON file:
{

What I am after is:
If the Workflow of "Acceptance" is selected, the fields under JOBACCEPT are required.
If the Workflow of "Rejection" is selected, the fields under JOBREJECT are required.
I have tried many different combinations of oneOf, allOf, anyOf, if-then-else but nothing seems to work correctly.
Anyone have any ideas what needs to be done?

You had the right idea. The problem is where you've placed the allOf with your conditionals. You have it in the "JobOffer" schema, but are trying to set constraints on the "Workflow" property which is in the "Transaction-Header" schema. There is no way to reference a property that is higher up in the JSON tree structure, so you need to move the allOf up into the "Transaction-Header" schema so you can set constraints on the "Workflow" property.
Now that it's in the right place, the best way to express your conditional constraints is with if/then. The context of the if/then is now the the "Transaction-Header" schema, so the then schemas needs to not just say what properties are required, they need to declare that those properties are in the "Job-Offer" object.
{
...
"defs": {
...
"Transaction-Header": {
...
"allOf": [
{ "$ref": "#/defs/JOBACCEPT" },
{ "$ref": "#/defs/JOBREJECT" }
]
},
"JOBACCEPT": {
"if": {
"type": "object",
"properties": {
"Workflow": { "enum": ["Acceptance"] }
},
"required": ["Workflow"]
},
"then": {
"properties": {
"Job-Offer": {
"required": ["Accepted", "Datetime-Accepted"]
}
}
}
},
"JOBREJECT": { ... Similar to JOBACCEPT ... }
}
}
You're abstracting everything away into definitions *, so it's tricky to express conditionals that reference things multiple layers deep. If you inline all the definitions, it gets a little easier to see what needs to be done.
The if/then keywords need to be at the level of 'Transaction'. In pseudocode:
"if the property 'Header' exists (i.e. required) and its value is ... (const), then require property ... with value (type=object, required properties=[...], property definitions=...)", and so on.
* by the way, in version 2020-12 the definitions keyword is $defs -- it may work the way you have it, but implementations will be unable to validate the schemas undef defs as they won't recognize them there, so some errors can slip through and be harder to find.
I have the following JSON which validates against my current schema:
{
"information": [
{
"value": "closed",
"type": "power"
},
{
"value": "on",
"type": "door"
}
]
}
However, I want this validation to fail (since open/closed should relate to door, and on/off should only relate to power.
How can I tie the two together?
My current working schema:
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"definitions": {
"Type": {
"type": "string",
"enum": ["power", "door"]
},
"Power": {
"type": "string",
"enum": ["on", "off"]
},
"Door": {
"type": "string",
"enum": ["open", "closed"]
},
"InformationField": {
"type": "object",
"required": [ "type", "value" ],
"properties": {
"label": { "type": "string" },
"value": {
"anyOf": [
{ "$ref": "#/definitions/Power"},
{ "$ref": "#/definitions/Door"}
]
},
"type": { "$ref": "#/definitions/Type" }
}
},
"Information": {
"type": "array",
"items": { "$ref": "#/definitions/InformationField" }
},
},
"properties": {
"information": { "$ref": "#/definitions/Information" }
},
}
I have a lot of types, so I want to do this in the cleanest way possible.
Here is one of my attempts, which fails to validate correctly:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"definitions": {
"Type": {
"type": "string",
"enum": ["power", "door"]
},
"Power": {
"type": "string",
"enum": ["on", "off"]
},
"Door": {
"type": "string",
"enum": ["open", "closed"]
},
"InformationField": {
"type": "object",
"required": [ "label", "value" ],
"properties": {
"label": { "type": "string" },
"type": { "$ref": "#/definitions/Type" }
},
"anyOf": [
{
"if": {
"properties": { "type": { "const": "power" } }
},
"then": {
"properties": { "value": { "$ref": "#/definitions/Power" } }
}
},
{
"if": {
"properties": { "type": { "const": "door" } }
},
"then": {
"properties": { "value": { "$ref": "#/definitions/Door" } }
}
}
]
},
"Information": {
"type": "array",
"items": { "$ref": "#/definitions/InformationField" }
},
},
"properties": {
"information": { "$ref": "#/definitions/Information" }
},
}
(Validates, even though it shouldn't ...)
Changed anyOf to allOf in my attempt, which fixes validation.
My reasoning as to why this works:
From the anyOf JSON schema spec:
5.5.4.2. Conditions for successful validation
An instance validates successfully against this keyword if it validates successfully against at least one schema defined by this keyword's value.
If my first if condition is false, then it doesn't evaluate the then, and is therefore valid.
Using allOf evaluates every condition's validation (not the condition itself).
As I am new to JSON schema creation, I have learnt the basics of JSON schema and now I am trying to create JSON schema for the below mentioned set of data,
{
"Result": [
{
"ResourceName": "Appointment",
"Sequence": "1",
"Data": {
"AppointmentID": "A1234",
"PatientName": "Test Patient",
"ClinicName": "Test Clinic"
}
},
{
"ResourceName": "EpisodeofCare",
"Sequence": "2",
"Data": {
"EpisodeID": "EP1234",
"LocationId": "L1234",
"AppointmentId": "A1234",
"TransactionStatus": "2",
"OPNumber": "OP523367"
}
},
{
"ResourceName": "Encounter",
"Sequence": "3",
"Data": {
"EncounterID": "E1234",
"PatientID": "P1234"
}
}
]
}
Can anybody please help me to create JSON schema for this kind of data set.
Thanks in advance for helping me out on this.
Below is the JSON schema i have drafted
{
"$schema": "http://json-schema.org/draft-07/schema#",
"definitions": {
"ResultType": {
"type": "object",
"properties": {
"ResourceName": {
"type": "string"
},
"Sequence": {
"type": "string"
},
"Data": {
"type": "object",
"anyOf": [
{
"$ref": "#/definitions/Appointment"
},
{
"$ref": "#/definitions/EpisodeofCare"
},
{
"$ref": "#/definitions/Encounter"
}
]
}
}
},
"Appointment": {
"type": "object",
"properties": {
"AppointmentID": {
"type": "boolean"
},
"PatientName": {
"type": "string"
},
"ClinicName": {
"type": "string"
}
}
},
"EpisodeofCare": {
"type": "object",
"properties": {
"EpisodeID": {
"type": "string"
},
"LocationId": {
"type": "string"
},
"AppointmentId": {
"type": "string"
},
"TransactionStatus": {
"type": "string"
},
"OPNumber": {
"type": "string"
}
}
},
"Encounter": {
"type": "object",
"properties": {
"EncounterID": {
"type": "string"
},
"PatientID": {
"type": "string"
}
}
}
},
"type": "object",
"properties": {
"Result": {
"type": "array",
"$ref": "#/definitions/ResultType"
}
}
}
Throw it in a schema validator like this one.
You will see errors in your schemas definition and in validation.
First of all check that your schema is valid json (the validator might help):
[
{
{"$ref": "#/definitions/Appointment"} <- unnecessary and invalid braces
},
{
{"$ref": "#/definitions/EpisodeofCare"} <- unnecessary and invalid braces
},
{
{"$ref": "#/definitions/Encounter"} <- unnecessary and invalid braces
}
]
Within the Result property you want each item of the array. You should use the item property instead of ref. As taken from the specification:
The value of "items" MUST be either a valid JSON Schema or an array of valid JSON Schemas.
[...]
If "items" is a schema, validation succeeds if all elements in the array successfully validate against that schema.
Thus you should use
{
"type": "object",
"properties": {
"Result": {
"type": "array",
"items": {
"$ref": "#/definitions/ResultType"
}
}
}
}
Since the schema should be as specific as possible you should constraint the content of the ResourceName properties to the actual data layout.
Use the const property to define a constant value for the ResourceName for each type of Resource. Take for example the Appointment type, which would change to:
"Appointment": {
"type": "object",
"properties": {
"ResourceName": {
"const": "Appointment"
},
"Data": {
"type": "object",
"properties": {
"AppointmentID": {
"type": "string"
},
"PatientName": {
"type": "string"
},
"ClinicName": {
"type": "string"
}
}
}
}
I also changed the type of AppointmentID to string.
Then your ResultType needs to be adjusted. Before you used anyOf to validate the data, now you need it to validate the complete object while still maintaining the overall structure:
"ResultType": {
"allOf": [
{
"type": "object",
"properties": {
"ResourceName": {
"type": "string"
},
"Sequence": {
"type": "string"
},
"Data": true
}
},
{
"anyOf": [
{
"$ref": "#/definitions/Appointment"
},
{
"$ref": "#/definitions/EpisodeofCare"
},
{
"$ref": "#/definitions/Encounter"
}
]
}
]
}
The allOf propertiy implies a and condition. The overall structure (the object) does not care what value ResourceName has or how Data is structured. The specific implementations (the anyOf part) take care of that.
Some final improvements. Use the required property to define the names of properties that must exist in your JSON file. Also add "additionalProperties": false to ensure that only the specified properties are used. And finally constraint your sequence values to be string representations of positive intergers by adding "pattern": "[1-9]\\d*".
Final result:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"definitions": {
"ResultType": {

you can create json schema by online tools which generates json schema from the json
like: https://www.liquid-technologies.com/online-json-to-schema-converter , it also checks if json is valid or not.
Json Schema that you need:
{

"type": "string"
},

}
},

I have a json file with nested objects.
{
"apiVersion":"0.0.9b",
"apiDate":"18.01.19",
"general":{
"documentType": "invoice",
"references":{
"invoiceId":"123",
"invoiceDate":"01.01.1970",
"creditNoteId":"123",
"creditNoteDate":"01.01.1970"
}
}
}
Now I would like to define that invoiceId and invoiceDate should be required if documentType is invoice, and also the other way arraound (creditNoteId and Date are required if documentType is creditNote).
All other Properties should be optional.
Pseudo-Code:
documentType = invoice
- required: invoiceId, invoiceDate
- optional: creditNoteId, creditNoteDate
documentType = creditNote
- required: creditNoteId, creditNoteDate
- optional: invoiceId, invoiceDate
If i store all properties in the same object I found this working solution:
{

Is there a way to display this dependency with nested objects used in the above json?
What I tried already was:
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"required": [
"apiVersion",
"apiDate"
],
"properties": {
"apiVersion": {
"type": "string",
"description": "The version of the json file"
},
"apiDate": {
"type": "string",
"description": "The date when the json version was published"
},
"general": {
"$ref": "#/definitions/general_identifiers"
},
"references": {
"type": "object",
"properties": {
"invoiceId": {
"type": "string"
},
"invoiceDate": {
"type": "string"
},
"creditNoteId": {
"type": "string"
},
"creditNoteDate": {
"type": "string"
}
},
"oneOf": [
{
"$comment": "Invoice",
"properties": {
"documentType": { "enum": ["invoice"] }
},
"required": ["invoiceId", "invoiceDate"]
},
{
"$comment": "CreditNote",
"properties": {
"documentType": { "enum": ["creditNote"] }
},
"required": ["creditNoteId", "creditNoteDate"]
}
]
}
},
"definitions" : {
"general_identifiers" : {
"type": "object",
"required": [
"documentType"
],
"properties": {
"documentType": {
"enum": [
"invoice",
"creditNote"
]
}
}
}
}
}
But with this i get an Error from https://www.jsonschemavalidator.net
Message: JSON is valid against more than one schema from 'oneOf'. Valid schema indexes: 0, 1.
What have I missed?
You're very close. You just need to pull your oneOf up to the top level so you can reference #/properties/general and #/properties/references from the same schema.
Also, you almost always want to use anyOf instead of oneOf. oneOf enforces that one and only one schema in the list validates. When the schemas are mutually exclusive, oneOf is just asking the validator to do unnecessary work.
"anyOf": [
{
"properties": {
"general": {
"properties": {
"documentType": { "enum": ["invoice"] }
}
},
"references": {
"required": ["invoiceId", "invoiceDate"]
}
}
},
{
"properties": {
"general": {
"properties": {
"documentType": { "enum": ["creditNote"] }
}
},
"references": {
"required": ["creditNoteId", "creditNoteDate"]
}
}
}
]
With the help of Jason Desrosiers I finaly found a solution also for my nested json.
{
"$schema": "http://json-schema.org/draft-07/schema#",
"type": "object",
"required": [
"apiVersion",
"apiDate"
],
"anyOf": [
{
"properties": {
"general": {
"properties": {
"documentType": { "enum": ["invoice"] },
"references": {
"required": ["invoiceId", "invoiceDate"]
}
}
}
}
},
{
"properties": {
"general": {
"properties": {
"documentType": { "enum": ["creditNote"] },
"references": {
"required": ["creditNoteId", "creditNoteDate"]
}
}
}
}
}
],
"properties": {
"apiVersion": {
"type": "string",
"description": "The version of the json file"
},
"apiDate": {
"type": "string",
"description": "The date when the json version was published"
},
"general": {
"$ref": "#/definitions/general_identifiers",
"references": {
"type": "object",
"properties": {
"invoiceId": {
"type": "string"
},
"invoiceDate": {
"type": "string"
},
"creditNoteId": {
"type": "string"
},
"creditNoteDate": {
"type": "string"
}
}
}
}
},
"definitions" : {
"general_identifiers" : {
"type": "object",
"required": [
"documentType"
],
"properties": {
"documentType": {
"enum": [
"invoice",
"creditNote"
]
}
}
}
}
}
I have the input json like below,
{"contents":[{"type":"field"},{"type":"field","itemId":"594b9980e52b5b0768afc4e8"}]}
the condition is,
if the type is 'field', then 'itemId' should be the required field
and if the type is 'fieldGroup' or 'subSection', then 'itemId' is optional
This is the Json Schema I tried and its not working as expected,
"type": "object",
"additionalProperties": false,
"properties" : {
"contents" : {
"type" : "array",
"items": {"$ref": "#displayItem" }
}
},
"definitions": {
"displayItem" : {
"id": "#displayItem",
"type": "object",
"items": {
"anyOf": [
{"$ref": "#fieldType"},
{"$ref": "#fieldGroupSubSectionType"}
]
}
},
"fieldType" : {
"id": "#fieldType",
"type": "object",
"additionalProperties": false,
"properties": {
"itemId": {
"type": "string"
},
"type": {
"type": "string",
"enum": ["field"]
}
}
},
"fieldGroupSubSectionType" : {
"id": "#fieldGroupSubSectionType",
"type": "object",
"additionalProperties": false,
"properties": {
"itemId": {
"type": [ "string", "null" ]
},
"type": {
"type": "string",
"enum": [
"fieldGroup",
"subSection"
]
}
}
}
}
Any help / workaround with Sample Json Schema to achieve the above use case is appreciated.
If I understand the description of what you want correctly, then the json example you provide is not valid since it has a type: "field" but does not have an "itemId" property.
Assuming that is true. Instead of using
type: ["string", null]
use the required property.
I changed your schema a bit, instead of having separate definitions I inlined them, but other than that (and the use of required) is the same:
{
"type": "object",
"additionalProperties": false,
"properties": {
"contents": {
"type": "array",
"items": {
"anyOf": [
{
"type": "object",
"additionalProperties": false,
"properties": {
"itemId": {
"type": "string"
},
"type": {
"type": "string",
"enum": [
"field"
]
}
},
"required": [
"itemId"
]
},
{
"type": "object",
"additionalProperties": false,
"properties": {
"itemId": {
"type": "string"
},
"type": {
"type": "string",
"enum": [
"fieldGroup",
"subSection"
]
}
}
}
]
}
}
}
}
Here is your answer with a little cleanup for best practices and style. The trick is that you need to use implication "a implies b <=> (not a) or b". In this case you have "type = field implies itemId is required <=> type is not field or itemId is required".
{
"type": "object",
"properties": {
"contents": {
"type": "array",
"items": { "$ref": "#/definitions/displayItem" }
}
},
"definitions": {
"displayItem": {
"type": "object",
"properties": {
"itemId": { "type": "string" },
"type": { "enum": ["field", "fieldGroup", "subSection"] }
},
"anyOf": [
{ "not": { "$ref": "#/definitions/fieldType" } },
{ "required": ["itemId"] }
]
},
"fieldType": {
"properties": {
"type": { "enum": ["field"] }
}
}
}
}
