Or just remove the constructs that have the word in it? Standards are not opinionated, they are specifications :P While Section 4 of [RFC7493] probably is not relevant to this specification Then why mention it here? |

Please find below some non-blocking COMMENT points (but replies would be appreciated even if only for my own education). Special thanks to A.J. Stein for the shepherd's detailed write-up including the WG consensus *and* the justification of the intended status. Please note that Henk Birkholz is the IoT directorate reviewer (at my request) and you may want to consider this iot-dir review as well when it will be available (no need to wait for it though): https://datatracker.ietf.org/doc/draft-ietf-cbor-cddl-more-control/reviewrequest/21141/ I hope that this review helps to improve the document, Regards, -éric ## COMMENTS (non-blocking) ### Title The title is really vague `More control operators`, suggest to use a more specific title, e.g., "Text Conversion and Processing Control Operators for CDDL". ### Section 2.1 Who is `we` in this context? The author? the WG? the whole IETF ? Please avoid using this sentence structure. Should `QR code` have an informational reference ? ### Section 3.1 I smiled a lot when reading IPv4 = legacy IP ;-) |

Please send substantive comments to the last-call@ietf.org mailing lists by 2024-11-20. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract The Concise Data Definition Language (CDDL), standardized in RFC 8610, provides "control operators" as its main language extension point. RFCs have added to this extension point both in an application-specific and a more general way. The present document defines a number of additional generally applicable control operators for text conversion (Bytes, Integers, JSON, Printf-style formatting) and for an operation on text. The file can be obtained via https://datatracker.ietf.org/doc/draft-ietf-cbor-cddl-more-control/ No IPR declarations have been submitted directly on this I-D. The document contains these normative downward references. See RFC 3967 for additional information: rfc9285: The Base45 Data Encoding (Informational - Internet Engineering Task Force (IETF) stream) |

The DT did not reflect the intended status as Proposed Standard. I believe it should be marked Proposed Standard, and have updated the DT. I am setting the substate to revised I-D needed, with the assumption that there will be at least a few changes incorporated as part of this review. ## Comments ### Is sloppy really needed? ``` 179 +--------------+-----------------------+------------------------+ 180 | .b64u-sloppy | Base64URL, no | Section 5 of [RFC4648] | 181 | | padding, sloppy | | 182 +--------------+-----------------------+------------------------+ ``` I wonder if all these productions are really necessary, or if by specifying support for them, we are encouraging them. I do not think it is generally good design to make use of multiple text encodings for binary in a single protocol, or to unnecessarily mix cbor and json encodings in protocols. Later you have: ``` 227 in not specifying a sloppy variant of base32 or base32/hex, as no 228 legacy use of sloppy base32(/hex) was known at the time of writing. ``` Why is `b64u-sloppy` worth specifying / encouraging the use of? ### Thanks for being opinionated ``` 208 Note that this specification is somewhat opinionated here: It does 209 not provide base64url, base32 or base32hex encoding with padding, or 210 base64 classic without padding. Experience indicates that these ``` Related to my comment above, I like this... and I wonder if there is room to be even stronger. ### validate the mandates of their base documents I am not sure what "validate the mandates of their base documents" means. ``` 215 These control operators are "strict" in their matching, i.e., they do 216 validate the mandates of their base documents. Note that this also 217 means that .b64u and .b64c only accept the alphabets defined for each 218 of them, respectively; this is maybe worth pointing out here 219 explicitly as CDDL's "b64" literal prefix simply accepts either 220 alphabet and this behavior is different from that of these control 221 operators. ``` This block could probably be re-written to use more traditional terminology from theory of computation related to recognizing regular languages. Perhaps even normative guidance of the form: The use of "b64" is NOT RECOMMENDED... because its alphabet is not restricted. Although I suppose this kind of normative text would lead to an update, and not an extension. Perhaps there is still a way to provide stronger guidance on the use of b64 without crossing this line. ### CBOR Unicode A reference to https://datatracker.ietf.org/doc/html/rfc8949#section-3.1-2.8 (or perhaps there is a better reference) might be worth adding here, to highlight that the space of UTF-8 is already reduced by encoding in CBOR? It would be repetition, but perhaps helpful to some readers. ``` 284 interpolate a text string in UTF-8 form. The 'c' conversion 285 specifier (paragraph 8) represents a single Unicode scalar value as a 286 UTF-8 character. The 'p' and 'n' conversion specifiers (paragraph 8) 287 are not used and MUST NOT be included in the format string. ``` ### Which JSON? ``` 305 Some applications store complete JSON texts into text strings, the 306 JSON value for which can easily be defined in CDDL. This is ``` - https://datatracker.ietf.org/doc/html/rfc7159 - https://datatracker.ietf.org/doc/html/rfc7493 ### Canonical JSON ``` 326 There is no way to constrain the use of blank space in data items to 327 be validated; variants (e.g, not providing for any blank space) could 328 be defined. ``` This basically means there is no way to distinguish JCS JSON from other flavors of JSON correct? https://datatracker.ietf.org/doc/html/rfc8785#name-whitespace Perhaps this is yet another opportunity to be opinionated, and recommend that protocols using CDDL to specify JSON... SHOULD omit whitespace tokens, and that this needs to be described in text, as it cannot be recognized by CDDL? ... or that JCS cannot be expressed in CDDL? Perhaps frame this "limitation" as a feature, and provide stronger guidance. ### Valid UTF-8 ``` 366 the strings. If the result of the concatenation is a text string, 367 the resulting sequence of bytes MUST be valid UTF-8. ``` I believe it is possible to be more precise than this, perhaps a reference to https://datatracker.ietf.org/doc/html/rfc8949#section-3.2.3 could also be useful here?... I would not want folks to think of this as a way to specify valid UTF-8, that might otherwise not be acceptable in the CBOR ecosystem, but perhaps this would be useful for CDDL? Is constructing examples of "bad" UTF-8 a use case for these controls, so that these bad examples can be recognized? ### Implementation Status ``` 440 5. Implementation Status 442 This section is to be removed before publishing as an RFC. 444 In the CDDL tool described in Appendix F of [RFC8610], the control 445 operators defined in the present revision of this specification are 446 implemented as of version 0.10.4. ``` As this section will be removed, but the reference to Appendix F of [RFC8610] will remain correct (?). I wonder if it is worth repeating something like Appendix F in this specification, and to provide new examples using the controls defined in this draft. ### Security Considerations ``` 448 6. Security considerations 450 The security considerations of [RFC8610] apply. ``` Are there no new security considerations introduced by this document? For example, maximum depth exceeded, nesting .json, .cbor, .b64 to create resource exhaustion attacks? Is there some CDDL equivalent of the ReDoS attack? The ability to produce troublesome unicode using these controls, or to produce or consume unicode in the context of JSON that could be harmful? Do the security considerations for JSON/I-JSON and Base64 also apply here? - https://datatracker.ietf.org/doc/html/rfc4648#section-12 - https://datatracker.ietf.org/doc/html/rfc7493#section-5 Is there a relationship between these controls and the use of CDDL for sanitizing untrusted user input? Is there a risk of deserialization of untrusted data (CWE-502) in implementations of these controls? Note the comment about buffer overflow in security considerations of RFC4648. ## Nits ### Order of CDDL This is a nit, but when I read CDDL like this, I always feel as if there should be some use before defined error. All the examples in this draft take the opposite approach, is this a convention which is documented or recommended somewhere? Encouraging a consistent style for CDDL could help reduce learning curve. ``` 167 signature-for-json = text .b64u signature 168 signature = bytes .cbor COSE_Sign1 ``` |

Among the … # Document Shepherd Write-Up for Group Documents *This version is dated 4 July 2022.* Thank you for your service as a document shepherd. Among the responsibilities is answering the questions in this write-up to give helpful context to Last Call and Internet Engineering Steering Group ([IESG][1]) reviewers, and your diligence in completing it is appreciated. The full role of the shepherd is further described in [RFC 4858][2]. You will need the cooperation of the authors and editors to complete these checks. Note that some numbered items contain multiple related questions; please be sure to answer all of them. ## Document History 1. Does the working group (WG) consensus represent the strong concurrence of a few individuals, with others being silent, or did it reach broad agreement? The document has strong concurrence of a few individuals (active in the CBOR Working Group and others with applications of CDDL). 2. Was there controversy about particular points, or were there decisions where the consensus was particularly rough? Having reviewed the mailing list and meeting notes, I have determined no controversy about particular points of the document. 3. Has anyone threatened an appeal or otherwise indicated extreme discontent? If so, please summarize the areas of conflict in separate email messages to the responsible Area Director. (It should be in a separate email because this questionnaire is publicly available.) No. 4. For protocol documents, are there existing implementations of the contents of the document? Have a significant number of potential implementers indicated plans to implement? Are any existing implementations reported somewhere, either in the document itself (as [RFC 7942][3] recommends) or elsewhere (where)? The author has already completed an initial implementation. Two WG contributors have written on the mailing list they plan to use the operators and/or make an additional implementation to process use of the operators. ## Additional Reviews 5. Do the contents of this document closely interact with technologies in other IETF working groups or external organizations, and would it therefore benefit from their review? Have those reviews occurred? If yes, describe which reviews took place. This draft extends control operators in CDDL as a data definition language for CBOR and JSON data. The document's contents are in use by downstream applications. One such application is members of the RATS Working Group, particularly using CDDL to define CBOR and JSON structures for the Entity Attestation Token in [draft-ietf-rats-eat](https://datatracker.ietf.org/doc/draft-ietf-rats-eat/29/). In particular, Laurence Lundblade and Jeremy O'Donoghue reviewed and provided precise feedback. Additionally, Rohan Mahy from the Message Layer Security Working Group has evaluated the operators and a reference implementation, providing feedback on the draft's specification on base64 and base64url decoding, and JSON-only content processing. 6. Describe how the document meets any required formal expert review criteria, such as the MIB Doctor, YANG Doctor, media type, and URI type reviews. This document does not require such IETF expert reviews, but does require IANA review and is appropriately prepared. See below for details. 7. If the document contains a YANG module, has the final version of the module been checked with any of the [recommended validation tools][4] for syntax and formatting validation? If there are any resulting errors or warnings, what is the justification for not fixing them at this time? Does the YANG module comply with the Network Management Datastore Architecture (NMDA) as specified in [RFC 8342][5]? This document does not contain a YANG module. 8. Describe reviews and automated checks performed to validate sections of the final version of the document written in a formal language, such as XML code, BNF rules, MIB definitions, CBOR's CDDL, etc. This draft contains six CDDL definition examples and they have been validated with the `cddl` tool [as documented in RFC 8610 Appendix F](https://datatracker.ietf.org/doc/html/rfc8610#autoid-54). ## Document Shepherd Checks 9. Based on the shepherd's review of the document, is it their opinion that this document is needed, clearly written, complete, correctly designed, and ready to be handed off to the responsible Area Director? Yes, I have reviewed the document and my assessment is that the document is necessary, written clearly, complete, correct and ready for handoff to the Area Director. 10. Several IETF Areas have assembled [lists of common issues that their reviewers encounter][6]. For which areas have such issues been identified and addressed? For which does this still need to happen in subsequent reviews? The [typical ART area issues](https://wiki.ietf.org/group/art/TypicalARTAreaIssues) are applicable to this work. Specifically, the base64 issues are applicable. The others have already taken care to properly address the different variations of base64 specified in Sections 4 and 5 in RFC4648 already. 11. What type of RFC publication is being requested on the IETF stream ([Best Current Practice][12], [Proposed Standard, Internet Standard][13], [Informational, Experimental or Historic][14])? Why is this the proper type of RFC? Do all Datatracker state attributes correctly reflect this intent? The RFC type of this publication is Proposed Standard. This follows from the other dependent RFCs that this document extends. The state attributes appear to be correct and reflect this intent. 12. Have reasonable efforts been made to remind all authors of the intellectual property rights (IPR) disclosure obligations described in [BCP 79][7]? To the best of your knowledge, have all required disclosures been filed? If not, explain why. If yes, summarize any relevant discussion, including links to publicly-available messages when applicable. The author confirmed [in a recent thread on the cbor mailing list](https://mailarchive.ietf.org/arch/msg/cbor/rdy2BWEiFH8aYR-TXndPoMx3K8Q/) that he is not aware of any patent claims. The author is very familiar with the process, stating in the thread: > (There was no need during the WG proceedings to remind me of the procedures we use to handle patent claims; I’m rather painfully aware of them.) 13. Has each author, editor, and contributor shown their willingness to be listed as such? If the total number of authors and editors on the front page is greater than five, please provide a justification. There is only one author for this I-D and they have demonstrated their willingness and commit to edit the draft and incorporate feedback. 14. Document any remaining I-D nits in this document. Simply running the [idnits tool][8] is not enough; please review the ["Content Guidelines" on authors.ietf.org][15]. (Also note that the current idnits tool generates some incorrect warnings; a rewrite is underway.) The [idnits tool report](https://author-tools.ietf.org/api/idnits?url=https://www.ietf.org/archive/id/draft-ietf-cbor-cddl-more-control-05.txt) has several errors and warnings, but all have been review and are false positives (BCP14 versus RFC2119; downref to published non-RFC standards; date; line length). 15. Should any informative references be normative or vice-versa? See the [IESG Statement on Normative and Informative References][16]. The placement of all normative and informative references is correct. 16. List any normative references that are not freely available to anyone. Did the community have sufficient access to review any such normative references? All normative references are freely available and therefore the community had sufficient access. A related issue brought up in discussion of the prior version of this shepherd review: C (ISO 9899) is definitely not a downref, but it is worth to point out that this document references this ISO standard normatively. There is a hyperlink to a source accessible without paywall. The RFC editor will likely know how to update with a more appropriate, reader-friendly hyperlink during the editor review process. 17. Are there any normative downward references (see [RFC 3967][9] and [BCP 97][10]) that are not already listed in the [DOWNREF registry][17]? If so, list them. There is a normative reference to an informational RFC listed below. It is important for review during last call and for follow-up by the area ADs. [RFC9285] Fältström, P., Ljunggren, F., and D.W. van Gulik, "The Base45 Data Encoding", RFC 9285, DOI 10.17487/RFC9285, August 2022, . 18. Are there normative references to documents that are not ready to be submitted to the IESG for publication or are otherwise in an unclear state? If so, what is the plan for their completion? No. 19. Will publication of this document change the status of any existing RFCs? If so, does the Datatracker metadata correctly reflect this and are those RFCs listed on the title page, in the abstract, and discussed in the introduction? If not, explain why and point to the part of the document where the relationship of this document to these other RFCs is discussed. Publication of this document will not change the status of existing RFCs. Th abstract explains this I-D's relationship to RFC9165, RFC9090, and RFC8160. RFC8610 is a foundational RFC for CDDL that establishes the first set of control operators in Section 3.8. This draft builds upon that set but does not conflict. Similarly, RFC9165 defines a set of new operators extending the original set in RFC8610. RFC9090 defines yet another set of CDDL operators pertaining to CBOR Tags, the primary subject of that standard. In all cases, authors have taken care to avoid conflicts and layer successively on top of one another, so no change in existing RFCs appear to be necessary. 20. Describe the document shepherd's review of the IANA considerations section, especially with regard to its consistency with the body of the document. Confirm that all aspects of the document requiring IANA assignments are associated with the appropriate reservations in IANA registries. Confirm that any referenced IANA registries have been clearly identified. Confirm that each newly created IANA registry specifies its initial contents, allocations procedures, and a reasonable name (see [RFC 8126][11]). The IANA considerations section of this draft has a table with the proper columns and format. It properly and accurately defines the relevant existing registry (IANA CDDL Control Operators Registry). There is no declaration of a new registry. 21. List any new IANA registries that require Designated Expert Review for future allocations. Are the instructions to the Designated Expert clear? Please include suggestions of designated experts, if appropriate. Below is the list of IANA registries requiring Designated Expert Review. - [IANA CDDL Control Operators Registry](https://www.iana.org/assignments/cddl/cddl.xhtml#cddl-control-operators) The instructions are clear given the simple fields of the registry and nature of the request.

Among the … # Document Shepherd Write-Up for Group Documents *This version is dated 4 July 2022.* Thank you for your service as a document shepherd. Among the responsibilities is answering the questions in this write-up to give helpful context to Last Call and Internet Engineering Steering Group ([IESG][1]) reviewers, and your diligence in completing it is appreciated. The full role of the shepherd is further described in [RFC 4858][2]. You will need the cooperation of the authors and editors to complete these checks. Note that some numbered items contain multiple related questions; please be sure to answer all of them. ## Document History 1. Does the working group (WG) consensus represent the strong concurrence of a few individuals, with others being silent, or did it reach broad agreement? The document has strong concurrence of a few individuals (active in the CBOR Working Group and others with applications of CDDL). 2. Was there controversy about particular points, or were there decisions where the consensus was particularly rough? Having reviewed the mailing list and meeting notes, I have determined no controversy about particular points of the document. 3. Has anyone threatened an appeal or otherwise indicated extreme discontent? If so, please summarize the areas of conflict in separate email messages to the responsible Area Director. (It should be in a separate email because this questionnaire is publicly available.) No. 4. For protocol documents, are there existing implementations of the contents of the document? Have a significant number of potential implementers indicated plans to implement? Are any existing implementations reported somewhere, either in the document itself (as [RFC 7942][3] recommends) or elsewhere (where)? The author has already completed an initial implementation. Two WG contributors have written on the mailing list they plan to use the operators and/or make an additional implementation to process use of the operators. ## Additional Reviews 5. Do the contents of this document closely interact with technologies in other IETF working groups or external organizations, and would it therefore benefit from their review? Have those reviews occurred? If yes, describe which reviews took place. This draft extends control operators in CDDL as a data definition language for CBOR and JSON data. The document's contents are in use by downstream applications. One such application is members of the RATS Working Group, particularly using CDDL to define CBOR and JSON structures for the Entity Attestation Token in [draft-ietf-rats-eat](https://datatracker.ietf.org/doc/draft-ietf-rats-eat/29/). In particular, Laurence Lundblade and Jeremy O'Donoghue reviewed and provided precise feedback. Additionally, Rohan Mahy from the Message Layer Security Working Group has evaluated the operators and a reference implementation, providing feedback on the draft's specification on base64 and base64url decoding, and JSON-only content processing. 6. Describe how the document meets any required formal expert review criteria, such as the MIB Doctor, YANG Doctor, media type, and URI type reviews. This document does not require such IETF expert reviews, but does require IANA review and is appropriately prepared. See below for details. 7. If the document contains a YANG module, has the final version of the module been checked with any of the [recommended validation tools][4] for syntax and formatting validation? If there are any resulting errors or warnings, what is the justification for not fixing them at this time? Does the YANG module comply with the Network Management Datastore Architecture (NMDA) as specified in [RFC 8342][5]? This document does not contain a YANG module. 8. Describe reviews and automated checks performed to validate sections of the final version of the document written in a formal language, such as XML code, BNF rules, MIB definitions, CBOR's CDDL, etc. This draft contains six CDDL definition examples and they have been validated with the `cddl` tool [as documented in RFC 8610 Appendix F](https://datatracker.ietf.org/doc/html/rfc8610#autoid-54). ## Document Shepherd Checks 9. Based on the shepherd's review of the document, is it their opinion that this document is needed, clearly written, complete, correctly designed, and ready to be handed off to the responsible Area Director? Yes, I have reviewed the document and my assessment is that the document is necessary, written clearly, complete, correct and ready for handoff to the Area Director. 10. Several IETF Areas have assembled [lists of common issues that their reviewers encounter][6]. For which areas have such issues been identified and addressed?

There are no relevant automated checks for these formal languages, but other checks for copy content via GitHub Actions. ## Document Shepherd Checks 9. Based on the shepherd's review of the document, is it their opinion that this document is needed, clearly written, complete, correctly designed, and ready to be handed off to the responsible Area Director? Yes, I have reviewed the document and my assessment is that the document is necessary, written clearly, complete, correct and ready for handoff to the Area Director. 10.

To the best of your knowledge, have all required disclosures been filed? If not, explain why. If yes, summarize any relevant discussion, including links to publicly-available messages when applicable. Reasonable efforts may have been made in IETF and interim working group meetings. However, I have been unable to find any public discussion (mailing list; GitHub; meeting notes) or relevant disclosures in datatracker.ietf.org. 13. Has each author, editor, and contributor shown their willingness to be listed as such? If the total number of authors and editors on the front page is greater than five, please provide a justification.

This shepherd review is my first, so I would to confirm that the error below regarding one normative reference is to an informational RFC listed below is not a false positive. Upon review, all other warnings and errors are false positives.
