Universität Bremen TZI CBOR (STD 94, RFC 8949) defines "Deterministically Encoded CBOR" in its Section 4.2, providing some flexibility for application specific decisions. To facilitate Deterministic Encoding to be offered as a selectable feature of generic encoders, the present document defines a CBOR Common Deterministic Encoding (CDE) Profile that can be shared by a large set of applications with potentially diverging detailed requirements. This document also introduces the concept of Application Profiles, which are layered on top of the CBOR CDE Profile and can address more application specific requirements. To demonstrate how Application Profiles can be built on the CDE, a companion document defines the application profile "dCBOR".
