2. Terminology

The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.

This document reuses terminology from JWT [RFC7519] and COSE [RFC8152].

StringOrURI

The "StringOrURI" term in this specification has the same meaning and processing rules as the JWT "StringOrURI" term defined in Section 2 of [RFC7519], except that it is represented as a CBOR text string instead of a JSON text string.

NumericDate

The "NumericDate" term in this specification has the same meaning and processing rules as the JWT "NumericDate" term defined in Section 2 of [RFC7519], except that it is represented as a CBOR numeric date (from Section 2.4.1 of [RFC7049]) instead of a JSON number. The encoding is modified so that the leading tag 1 (epoch-based date/time) MUST be omitted.

Claim Key

The CBOR map key used to identify a claim.
