warning: format attribute "date" not supported

[hminds-ritesh]

Hi,

I have a JSON schema which has a property "BIRTH_DATE" with format as "date".

"BIRTH_DATE" : {
"description" : "BIRTH DATE",
"format" : "date",
"type" : "string"
},

Whenever I try to validate a json payload after this schema, the validator succeeds but shows up a warning:

warning: format attribute "date" not supported
level: "warning"
schema: {"loadingURI":"#","pointer":"/definitions/MemberDemographicJsSchema/properties/BIRTH_DATE"}
domain: "validation"
keyword: "format"
attribute: "date"

Am I doing anything wrong here? Or json validator does not support date format? If later, then how do I validate the date?

Regards,
Ritesh

Hello,

This is a poor choice on my part when writing draft v4; of all the date/time attributes, only date-time is supported; date and time were pulled out. They will be back in draft v5 however.

So, this message is normal. However, you can add them back programmatically:

final Library library = DraftV4Library.get().thaw()
    .addFormatAttribute("date", DateAttribute.getInstance())
    .freeze();

final ValidationConfiguration cfg = ValidationConfiguration.newBuilder()
    .setDefaultLibrary("http://some.site/myschema#", library).freeze();

final JsonSchemaFactory factory = JsonSchemaFactory.newBuilder()
    .setValidationConfiguration(cfg).freeze();

You can then build schemas from this factory: they will support this format attribute.

Hi,

I still see the same warning after adding the code that you mentioned.
Not sure if I am doing anything wrong.

Can you post your full code?

Apologizes for the late response.

Here is my code and I think there is something wrong with the way I am adding the default library. I copied draft4 schema in my local drive and referring the same (in the below code)

public static void main (String[] args) throws IOException {
    final Library library = DraftV4Library.get().thaw()
        .addFormatAttribute("date", DateAttribute.getInstance())
        .freeze();

    final ValidationConfiguration cfg = ValidationConfiguration
        .newBuilder()
        .setDefaultLibrary("file:///D:/work/ZeOmega/zeomega_wso2/schema.json", library)
        .freeze();

    final JsonSchemaFactory factory = JsonSchemaFactory.newBuilder()
        .setValidationConfiguration(cfg).freeze();

    try {
        JsonNode json = Utils.loadResource("D:/work/ZeOmega/zeomega_wso2/jiva_member.json");
        JsonNode jsonSchema = Utils.loadResource("D:/work/ZeOmega/zeomega_wso2/jiva_member_post_schema.json");
        JsonSchema schema = factory.getJsonSchema(jsonSchema);
        ProcessingReport report = schema.validate(json);
        System.out.println(report);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

Hi,

Any update on this?

[jeegarmaru]

I got this to work. I needed to change the value of the $schema field in the JSON schema file to not be "http://json-schema.org/draft-04/schema#" or any of the supported schemas.

Change it to the same value as what you use in the setDefaultLibrary (I used "http://mycompany.com/myschema#").

Thanks Jeegar. I shall try this.

Regards,

Ritesh

(sorry for the long delay)

What @jeegarmaru said; see also the examples as to how to modify your library to add a format attribute.

Hi @fge this is still giving me the same error even after changing the $schema.Please help.
