As an example, the import of ietf-interfaces has a reference to RFC 7223. But we know that ietf-interfaces is going to updated soon by whatever RFC number gets assigned to rfc7223bis. Expect further guidance on this. Mahesh As you doubtless know, this I-D is expected to be approved on March 8th, so there is a certain urgency about this. The latest guidelines, draft-ietf-netmod-rfc6087bis-18, include For every import or include statement that appears in a module contained in the specification, which identifies a module in a separate document, a corresponding normative reference to that document MUST appear in the Normative References section. which seems clear and right to me. This also says to me that a specific version of the module is referenced via the Normative References whether or not the import has a revision clause. and it also says If an import statement is for a module from a stable source (e.g., an RFC for an IETF module), then a reference-stmt SHOULD be present within an import statement. So for me there is (almost) always a reference statement to an RFC (or I-D) even, or especially when, no particular revision is wanted. This is what has coloured my comments on YANG modules. Tom Petch > Also, I do not see normative references to RFC 6991, and RFC 7223 in the text of the document. If this is not clear, see rfc7223bis, where in Section 3.1, there is normative reference to RFC7224 for the iana-if-types module that is imported by the ietf-interfaces module. > > Cheers. > > > > > https://datatracker.ietf.org/doc/draft-ietf-i2rs-rib-data-model/ > > > > Best regards, > > Amit > > > > -----Original Message----- > > From: Ebben Aries [mailto:exa@xxxxxxxxxxx] > > Sent: Thursday, January 18, 2018 9:33 AM > > To: yang-doctors@xxxxxxxx > > Cc: i2rs@xxxxxxxx; draft-ietf-i2rs-rib-data-model.all@xxxxxxxx; ietf@xxxxxxxx > > Subject: Yangdoctors early review of draft-ietf-i2rs-rib-data-model-09 > > > > Reviewer: Ebben Aries > > Review result: On the Right Track > > > > 1 module in this draft: > > - ietf-i2rs-rib@xxxxxxxxxxxxxxx > > > > No YANG validation errors or warnings (from pyang 1.7.3 and yanglint 0.14.59) > > > > 0 examples are provided in this draft (section 3.12 of > > draft-ietf-netmod-rfc6087bis-15) > > > > Module ietf-i2rs-rib@xxxxxxxxxxxxxxx: > > - yang-version statement missing - should be 1.1 > > - prefix 'iir' is recommended for this module, would 'rib' suffice better? > > - import "ietf-inet-types" should reference RFC 6991 per (not as a comment) > > https://tools.ietf.org/html/draft-ietf-netmod-rfc6087bis-15#section-4.7 > > - import "ietf-interfaces" should reference RFC 7223 per > > https://tools.ietf.org/html/draft-ietf-netmod-rfc6087bis-15#section-4.7 > > This should reference rfc7223bis. > > > - import "ietf-yang-types" should reference RFC 6991 per > > https://tools.ietf.org/html/draft-ietf-netmod-rfc6087bis-15#section-4.7 > > - Since this module imports "ietf-interfaces", a normative references must be > > added per > > https://tools.ietf.org/html/draft-ietf-netmod-rfc6087bis-15#section-3.9 > > - prefix "if" in the import "ietf-interfaces" can remove quotes to remain > > consistent with other imports > > - Remove WG Chairs from contact information per > > https://tools.ietf.org/html/draft-ietf-netmod-rfc6087bis-15#appendix-C > > - Module description must contain most recent copyright notice per > > https://tools.ietf.org/html/draft-ietf-netmod-rfc6087bis-15#appendix-C > > - Module description should contain note to RFC Ed. and placeholder reference > > to RFC when assigned > > https://tools.ietf.org/html/draft-ietf-netmod-rfc6087bis-15#appendix-C > > - Add placeholder reference and note to RFC Ed. for RFC when assigned > > https://tools.ietf.org/html/draft-ietf-netmod-rfc6087bis-15#appendix-C > > - Security Considerations should be updated to reflect new template at > > https://trac.ietf.org/trac/ops/wiki/yang-security-guidelines > > - Section 1.2 should be replaced with reference to > > draft-ietf-netmod-yang-tree-diagrams-02 rather (as-is in other i2rs YANG > > drafts in progress) per > > https://tools.ietf.org/html/draft-ietf-netmod-rfc6087bis-15#section-2.5. 1 > > - This module contains '12' features.
