Network Working Group T. Bray, Ed. Internet-Draft Textuality Services Intended status: Standards Track December 18, 2014 Expires: June 21, 2015 The I-JSON Message Format draft-ietf-json-i-json-05 Abstract I-JSON is a restricted profile of JSON designed to maximize interoperability and increase confidence that software can process it successfully with predictable results.

Introduction RFC 7159 describes the JSON data interchange format, which is widely used in Internet protocols. For historical reasons, that specification allows the use of language idioms and text encoding patterns which are likely to lead to interoperability problems and software breakage, particularly when a program receiving JSON data uses automated software to map it into native programming-language structures or database records. RFC 7159 describes practices which may be used to avoid these interoperability problems. This document specifies I-JSON, short for "Internet JSON". The unit of definition is the "I-JSON message". I-JSON messages are also "JSON texts" as defined in RFC 7159 but with certain extra constraints which enforce the good interoperability practices described in that specification. 1.1. Terminology The terms "object", "member", "array", "number", "name", and "string" in this document are to be interpreted as described in RFC 7159 [RFC7159]. 1.2. Requirements Language The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].
