Awesome, thanks a lot Marco! Tracked here: https://github.com/core-wg/core-problem-details/issues/17 Cheers, t From: core <core-bounces@ietf.org> on behalf of Marco Tiloca <marco.tiloca=40ri.se@dmarc.ietf.org> Date: Monday, 16 May 2022 at 08:47 To: Marco Tiloca <marco.tiloca=40ri.se@dmarc.ietf.org>, core@ietf.org WG (core@ietf.org) <core@ietf.org> Cc: cbor@ietf.org <cbor@ietf.org>, httpapi@ietf.org <httpapi@ietf.org> Subject: Re: [core] WG Last Call on draft-ietf-core-problem-details Hi all, Please find below my review comments. Best, /Marco [Section 1.1] * Please add the usual remark "Readers are expected to be familiar with ..." [Section 2] * The caption of Figure 2 can better say "Concise Problem Details Data Item". * The definition of the 'title' entry says: "It SHOULD NOT change from occurrence to occurrence of the problem." Do you mean "of the same problem" ? * The definition of 'response-code' can be expanded to also point to Section 3 of RFC 7252, and explicitly say that the response code here is exactly the value of the 'Code' field in the header of the CoAP response. This would complement the statement and example in the last paragraph of the section. * When defining the entry 'response-code', it is good to have a pointer also to Section 3.2 of RFC 8132, thus covering also 4.09 and 4.22. * "Note that, unlike [RFC7807], Concise Problem Details data items have no explicit type." Consistently, please consider the following changes to avoid possible confusion: - In Section 1, use "problem classes" rather than "problem types". - In Section 2, use "summary of the problem class" rather than "summary of the problem type" when defining the 'title' entry. A few paragraphs below, "shorthand for the category of the error" can also become "shorthand for the class of the error". - In Section 3, use "generic problem class container" rather than "generic problem type container". - In Section 5.1, as to the "Brief description" for 'title' in Table 1, use "problem class" rather than "problem type". [Section 3.1] * "Consumers of a Concise Problem Details instance MUST ignore ..." I think it is better to use "data item" rather than "instance". That would be consistent with the text in other sections and would avoid confusion with the 'instance' entry. [Section 3.2] * "Consumers of a Concise Problem Details instance MUST ignore ..." See the comment above about using "data item" rather than "instance". * Is it admitted to change the definition of an already existing Custom Problem Details entry, by updating the related documentation? Or is it something to discourage or even forbid, rather preferring a new entry to be defined altogether? [Section 5.1] * For 'title' and 'detail', shouldn't the CDDL Type be "text/array", rather than "text"? If tag 38 is used, that applies to an array, as per Appendix A.2.
