Introduction [RFC6020] defines a registry for YANG module and submodule names, called "YANG Module Names" [IANA-MOD-NAMES]. Specifically, IANA considerations to register YANG module and submodule names are specified in Section 14 of [RFC6020]. These considerations require that all module and submodule names in the registry must be unique. However, the practice followed by IANA is not consistent with that guidance. This document amends the guidance on the uniqueness of names (Section 14 of [RFC6020]) to comply with the IANA practices for registering modules and their revisions. 2. Requirements Notation 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. Bierman, et al. Expires 27 November 2025 [Page 2] Internet-Draft YANG Module Names May 2025 3. IANA Considerations 3.1. Update YANG Parameters Registry This document requests IANA to update the reference for the "YANG Module Names" registry under the "YANG Parameters" registry group [IANA-MOD-NAMES] to also list to the RFC number that will be assigned to this document. This update is needed because the procedure in this document is authoritative for assigning names in that registry. 3.2. Revisions of Published Modules This document amends the guidance on the uniqueness of names, initially defined in Section 14 of [RFC6020], as follows: OLD: All module and submodule names in the registry MUST be unique. All XML namespaces in the registry MUST be unique. NEW: Modules and their revisions are maintained in the registry. All initial version module and submodule names in the registry MUST be unique. All XML namespaces of initial version modules in the registry MUST be unique. All modules and submodules revisions MUST have the same name as the one in the initial version of the module and submodule. All module revisions MUST have the same XML namespace as the initial version of the module. 4. Operations and Manageability Considerations This document aligns an IANA policy with the practice for handling YANG module names (Section 3.2). As such, there are no new operations or manageability requirements introduced by this document. Bierman, et al. Expires 27 November 2025 [Page 3] Internet-Draft YANG Module Names May 2025 5. Security Considerations This document defines a new IANA action (Section 3.1) and defines an update (Section 3.2) to an IANA registration procedure defined in [RFC6020]. It does not introduce any new or increased security risks that need to be discussed. 6. References 6.1.
