[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.¶
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 requests IANA to update the reference for the "YANG Module Names" registry under the "YANG Parameters" registry group [IANA-MOD-NAMES] to point to the RFC number that will be assigned to this document.¶
This document amends the guidance on the uniqueness of names, initially defined in Section 14 of [RFC6020], as follows:¶
All module and submodule names in the registry MUST be unique.¶
All XML namespaces in the registry MUST be unique.¶
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.¶
This document defines an update to an IANA registration procedure defined in [RFC6020]. It does not introduce any new or increased security risks that need to be discussed.¶
