The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-sacm-coswid/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- Thank you for the work on this document. Many thanks to Rich Salz for his review: https://mailarchive.ietf.org/arch/msg/art/adGh-_pOSDVJObN06Qps2Scilts/ and thanks to the authors for addressing it. I support Rob's first DISCUSS point: I had the same reaction when reading that text. I also have some additional comments, mostly having to do with the use of SHOULD in the document. Francesca 1. ----- * If the patch item is set to "true", the tag SHOULD contain at least one link item (see Section 2.7) with both the rel item value of "patches" and an href item specifying an association with the software that was patched. * If the supplemental item is set to "true", the tag SHOULD contain at least one link item with both the rel item value of "supplemental" and an href item specifying an association with the software that is supplemented. FP: This is missing text about why these are SHOULD and not MUST or MAY. I agree with John Klensin, who formulated it very clearly: If SHOULD is used, then it must be accompanied by at least one of: (1) A general description of the character of the exceptions and/or in what areas exceptions are likely to arise. Examples are fine but, except in plausible and rare cases, not enumerated lists. (2) A statement about what should be done, or what the considerations are, if the "SHOULD" requirement is not met. (3) A statement about why it is not a MUST. 2. ----- * artifact (index: 37): To be used with rel="installation-media", FP: Should "installation-media" be "installationmedia" instead? 3. ----- * date (index 35): The date and time the information was collected pertaining to the evidence item. FP: Please add a reference to Section 3.4.1 [RFC8949] and mention that this is the standard date/time string. 4. ----- space, the "decimal" version scheme SHOULD be used. FP: Here (and following bullets) is another case that either requires a better context description about the use of SHOULD, or should be rephrased (possibly avoiding the BCP 14 SHOULD) for example: space, it is expected that the "decimal" version be used. 5. ----- Section 4.3 FP: Another place where SHOULD appears without explanation.
