CDE is deterministic encoding for the whole CBOR data model. It works only at the serialization level. It’s important to have a standard for determinism that covers the whole data model.

dCBOR layers over CDE and additionally works at the data model level. The main use case is deterministically serializing complex data directly from a database so that hashes of it can be exchanged without exchanging the data.

One of the reasons I like dCBOR as a standard is that its data model is similar to JSON (and JSON is very popular). A lot of (JSON) people that are confused by things like 65-bit integers and NaN payloads will find it much easier to understand and implement.
