Parsing composite schema object definition

[gauamg]

Thank you very much for making this library available as open source. This is extremely useful and I am glad I chanced upon it before giving up. I am using this library to build a quality check tool that scans JSON schemas for compliance with certain design standards. There is one particular design pattern (composition) that seems to be slipping through the parser. Here is the schema snippet: "BaseAddress": { "type": "object", "properties": { "addressLineText": { "$ref": "#/definitions/String50" }, "addressUnitIdentifier": { "$ref": "#/definitions/String11" }, "cityName": { "$ref": "#/definitions/String35" }, "postalCode": { "$ref": "#/definitions/PostalCodeType" } } }, "ResidenceAddress": { "allOf": [ { "$ref": "#/definitions/BaseAddress" }, { "properties": { "stateCode": { "$ref": "#/definitions/ResidenceStateCodeType" } } } ], "required": [ "addressLineText", "cityName", "postalCode", "stateCode" ] }, While the BaseAddress object is being correctly read, the ResidenceAddress object is not being recognized. What am I missing?

It's hard to say with that snippet; I'd need to know what you think should fail validation that isn't (or vice versa). Could I see the complete schema (paricularly as $ref works differently between different schema versions) and some example data?

Thanks for responding so promptly. I guess, I did not explain my problem clearly enough. I am not trying to validate an instance JSON document - I am trying to parse a schema to look for certain features. Here is a more complete version of the schema:

So, I am loading the sub schemas and trying to iterate through them -

Map<URI, Schema> subSchemas = schema.getSubSchemas(); Set uris = subSchemas.keySet(); Iterator itr1 = uris.iterator(); while (itr1.hasNext()) { ...... Schema s = subSchemas.get(key); .. s.getExplicitTypes()....... }

What I am seeing is that for all the sub schemas below, barring the composite ones - "ResidenceAddress" and "SubjectPropertyAddress" - the getExplicitTypes() call is returning "object" - which is correct, but for the two composite objects the value being returned is null. Am I not using the library correctly? What am I missing?

{ "$schema": "https://json-schema.org/draft-07/schema#", "title": "", "description": "", "type": "object", "properties": { "Application": { "type": "object", "description": "Application", "properties": { "Borrowers": { "$ref": "#/definitions/Borrowers" } } } }, "definitions": { "Borrower": { "type": "object", "properties": { "ResidenceAddress": { "$ref": "#/definitions/ResidenceAddress" } } }, "Borrowers": { "type": "array", "items": { "$ref": "#/definitions/Borrower" }, "minItems": 1, "maxItems": 2 }, "BaseAddress": { "type": "object", "properties": { "addressLineText": { "$ref": "#/definitions/String50" }, "addressUnitIdentifier": { "$ref": "#/definitions/String50" }, "cityName": { "$ref": "#/definitions/String50" }, "postalCode": { "$ref": "#/definitions/String50" } } }, "ResidenceAddress": { "allOf": [ { "$ref": "#/definitions/BaseAddress" }, { "properties": { "stateCode": { "$ref": "#/definitions/ResidenceStateCodeType" } } } ], "required": [ "addressLineText", "cityName", "postalCode", "stateCode" ] }, "SubjectPropertyAddress": { "allOf": [ { "$ref": "#/definitions/BaseAddress" }, { "properties": { "countyName": { "$ref": "#/definitions/String50" }, "stateCode": { "$ref": "#/definitions/SubjectPropertyStateCodeType" } } } ], "required": [ "stateCode" ] }, "String50": { "type": "string", "maxLength": 50 }, "ResidenceStateCodeType": { "type": "string", "enum": [ "AA", "BB" ] }, "SubjectPropertyStateCodeType": { "type": "string", "enum": [ "CC", "DD" ] } } } Thanks again for building this very useful library. Regards.

Hi sorry I haven't had time to investigate this yet.

No problem. Appreciate you getting back.

You miss the "type": "object" definition in schema.
