Internet Object 1.0

Internet Object is a text-based, schema-first, document-oriented data interchange format — JSON's readability without its repeated keys, missing schema, absent comments, or lack of streaming. This site is the official specification and serves as the format's reference documentation.

Status. This is the 1.0 Draft of the specification, published alongside the public beta of the reference implementation. The specification and the implementation are still converging, so some pages note behavior that is ahead of the current implementation. Implementations version independently and declare the specification version they conform to.
