Updates to the Concise Data Definition Language Grammar
RFC 9682, “Updates to the Concise Data Definition Language Grammar”, is a Proposed Standard document published in November 2024 by C. Bormann. It updates RFC 8610. The canonical text is published by the RFC Editor.
Abstract
The Concise Data Definition Language (CDDL), as defined in RFCs 8610 and 9165, provides an easy and unambiguous way to express structures for protocol messages and data formats that are represented in Concise Binary Object Representation (CBOR) or JSON.
This document updates RFC 8610 by addressing related errata reports and making other small fixes for the ABNF grammar defined for CDDL.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
