Logical Model for the HCERT

​The full data structure and encoding mechanisms for HCERT are defined here: Electronic Health Certificate Specification

An HCERT is claim -260 within the CBOR Web Token (CWT) Claim.

Note for subclaims:

- subclaims 0 and above are reserved by WHO to be assigned, a new sub claim can be requested for by requesting to create a new trust domain
- subclaims for negative integer values are for development purposes and are free to use
- While this logical model mentions assigned subclaims (below), the ones listed in the Electronic Health Certificate Specification are considered authoritative

Usage:

- Use this Logical Model Profile: CBOR Web Token (CWT) Payload (Common)
