===== Tools =====

==== Online ====

  * [[http://jslint.com/|JsLint]] - a well known/used //code quality tool// for validating JSON.
  * [[http://braincast.nl/samples/jsoneditor/|JSON Editor]] - (I haven't used this one yet, but it purports to provide a GUI-ish interface for editing JSON.)

==== Visual Studio ====

(See [[.NET Development]] -> [[.NET Development#Visual Studio]] -> [[.NET Development#JSON & JSON Schema]])

==== Other ====

  * [[http://sourceforge.net/projects/jslintnpp/|JSLint plugin for Notepad++]] - should also be available via the [[http://npppluginmgr.sourceforge.net/|Plugin Manager]], which is typically installed by default.
  * ''[[https://stedolan.github.io/jq/|jq]]'' //is a lightweight and flexible command-line JSON processor.// It can be used to query and transform JSON.
  * [[http://jwt.io/|JSON Web Token (JWT)]] - //a compact URL-safe means of representing claims to be transferred between two parties.//

===== JSON Schema =====

  * http://json-schema.org/ is the official home of JSON Schema.
  * //[[https://spacetelescope.github.io/understanding-json-schema/index.html|Understanding JSON Schema]]// is a very useful online book for getting started.
  * The Jasonary project also has some [[http://jsonary.com/documentation/json-schema/|useful documentation]].

==== Tools ====

  * [[http://json-schema-validator.herokuapp.com/|JsonSchema validation]] - Draft 4 is assumed. Provides:
    * Validation of data against your own schema
    * Schema syntax validation
    * Java <=> Json Schema
    * etc.
  * [[http://jsonvalidate.com/|JSON Validate]] - can provide schema, content and/or references for input.
  * [[http://jsonschema.net/|JSON Schema.net]] - validates JSON or JSON Schema, with form-based editing for blocks of JSON. Will also generate a Schema from JSON data.

==== Datetime values ====

JSON Schema does not support a ''datetime'' type directly. Instead, specify a ''string'' type with the ''format'' attribute:

<code javascript>
{
    "type": "object",
    "properties": {
        "StartDate": {
            "type": "string",
            "format": "date-time"
        }
    }
}
