Schemas

• RFC 8785 JCS: JSON Canonicalization Scheme

• CoverageJSON is a data format for describing “coverage” data in JavaScript Object Notation (JSON), and provides an overview of its design and capabilities.
• NetJSON is a data interchange format based on JavaScript Object Notation (JSON) designed to describe the basic building blocks of layer2 and layer3 networking.
• OpenAPI defines a standard, programming language-agnostic interface description for REST APIs
• JSON Feed a format similar to RSS and Atom but in JSON.
• JSON Canvas an open file format for infinite canvas data.

Encryption

• JOSE
• objecthash A way to cryptographically hash objects (in the JSON-ish sense) that works cross-language. And, therefore, cross-encoding.

Variant Format

Formats Similar to JSON.

• Hjson is a syntax extension to JSON. It’s NOT a proposal to replace JSON or to incorporate it into the JSON spec itself. It’s intended to be used like a user interface for humans, to read and edit before passing the JSON data to the machine.
• RSON file format is easy to edit, diff, and version control, that is a superset of JSON and smaller than YAML.
• rsonlite is the easiest way to create custom indented data file formats in Python. It is a single small module that can be shipped with your application, or it can be easy-installed or pipped from PyPI.
• LJSON JSON extended with pure functions.
• LJSON(Loose JSON) a superset of JSON with a loose format requirement.
• JSON Lines also called newline-delimited JSON. JSON Lines is a convenient format for storing structured data that may be processed one record at a time.
• Jsonnet A data templating language for app and tool developers.
• JSON5 The JSON5 Data Interchange Format (JSON5) is a superset of JSON that aims to alleviate some of the limitations of JSON by expanding its syntax to include some productions from ECMAScript 5.1.
• HOCON(Human-Optimized Config Object Notation) is a format for human-readable data, and a superset of JSON and .properties.
• Rison is a data format focus on URL friendly and compact. The structure is like JSON, but use different character for notation.
• JSONC JSON with Comments. parser

Related Format

Not Similar to JSON, but related to it.

• Mark is a new unified notation for both object and markup data. The notation is a superset of what can be represented by JSON, HTML and XML, but overcomes many limitations these popular data formats, yet still having a very clean syntax and simple data model.

Binary

• RFC 8949 CBOR: Concise Binary Object Representation
  • RFC 8152 COSE: CBOR Object Signing and Encryption
  • RFC 8392 CWT: CBOR Web Token
  • RFC 8610 CDDL: Concise Data Definition Language
• MessagePack is an efficient binary serialization format. It lets you exchange data among multiple languages like JSON.
• BSON short for Bin­ary JSON, is a bin­ary-en­coded seri­al­iz­a­tion of JSON-like doc­u­ments.
• BJSON is binary form of JSON.
• UBJSON(Universal Binary JSON) The universally compatible format specification for binary JSON.

XML

• JXON (lossless JavaScript XML Object Notation) is a generic name by which is defined the representation of JavaScript Objects using XML.
• JSONx is an IBM® standard format to represent JSON as XML.

Markdown

• MSON is a plain-text, human and machine readable, description format for describing data structures in common markup formats such as JSON, XML or YAML.

General

• YAML is a human-readable data serialization language.
• TOML aims to be a minimal configuration file format that’s easy to read due to obvious semantics.

Protocol

• JSON API
• JSON-RPC is a stateless, light-weight remote procedure call (RPC) protocol.

• Collection+JSON is a JSON-based read/write hypermedia-type designed to support management and querying of simple collections.
• OData JSON Format
• JSON Graph is a convention for modeling graph information as a JSON object. Applications that use Falcor represent all their domain data as a single JSON Graph object.

Tool

• JSONiq is a query and processing language specifically designed for the popular JSON data model.
• JSONDiffPatch
• JSONLint
• JSON Formatter was created to help with debugging. As JSON data is often output without line breaks to save space, it is extremely difficult to actually read and make sense of it.
• jq is like sed for JSON data - you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text.
• gron transforms JSON into discrete assignments to make it easier to grep for what you want and see the absolute ‘path’ to it.
• JSON Generator tool for generate random JSON data.
• fx is another command-line JSON processing tool.
• Ajv JSON validation tool supports JSON Schema and JSON Typedef
• JSON Typedef tools
• jless

History

• Comments in JSON exists at first

  Comments in JSON

  I removed comments from JSON because I saw people were using them to hold parsing directives, a practice which would have destroyed interoperability. I know that the lack of comments makes some people sad, but it shouldn’t.

  Suppose you are using JSON to keep configuration files, which you would like to annotate. Go ahead and insert all the comments you like. Then pipe it through JSMin before handing it to your JSON parser.

Blue?

Its hard to find a good domain available. And I love the color blue. Also, I am a fan of Dragon Ball. Super Saiyan Blue is very powerful. So I take the name.
