Re: JSON schema does not validate against valid data (validictory)

[Geraint]

I'm afraid yes - that schema is wrong.

The JSON Schema Generator is slightly buggy - it only accepts "object"s as top-level data.  You, however, want the top-level type to be "array":

schema = {

    "$schema": "http://json-schema.org/draft-03/schema",

    "type": "array" ,

    "items": {

        "type": "object" ,

        "properties": {
            ...

        }

    }

}

The following data + JSON schema (generated from using JSON Schema Generator with the same data) is supposed to validate correctly. However instead I receive a valdation error here.

The validation is based on the validictory module.

data = [{u'text': 

         u'<h1>The quick brown fox</h1>', 

         u'title': u'hello world', 

         u'location': u'Berlin',

                },

                "text" : {

                    "required": False,

                    "type": "string"

                },

                "title" : {

                    "id": "http://jsonschema.net/0/title",

                    "required": False,

                    "type": "string"

                }

            }

        }

    }

}

print validictory.validate(data,schema)

validictory.validator.FieldValidationError: Value [{u'text': u'<h1>The quick brown fox</h1>', u'created': u'2013-03-12T12:13:14', u'location': u'Berlin', u'title': u'hello world'}] for field '_data' is not of type objec

So is the schema for this data wrong?

I contacted the author of the jsonschema.net tool about this bug, actually, and they said it would be fixed, but that was a little while ago...
