Hi, OPS-DIR, Authors,







 







I have reviewed this document as part of the Operational directorate's ongoing effort to review all IETF documents being processed by the IESG. These comments were written with the intent
 of improving the operational aspects of the IETF drafts. Comments that are not addressed in last call may be included in AD reviews during the IESG review. Document editors and WG chairs should treat these comments just like any other last call comments.







 




This Standards Track document defines a


new CoAP methods, FETCH, to perform the equivalent of a GET with a request body; and the twin methods PATCH and iPATCH, to modify parts of a CoAP resource.


 This document is well written. I don't see any major issues from the operations and management perspective. It is almost ready to be published. There are one of potential major (the word potential means I don’t really sure how serious it may be) comments from
 me:




 




In section 2.5, it raises an issue that “

a
 FETCH request cannot be generated from a link alone, but also needs a way to generate the request payload.” From the discussion text, I am not sure whether there are existing way to generate the request payload or not. And I am not sure whether the FECTCH
 method needs a standard such way to be able to work or not. If the answer for my first question is no, or the question for my second question is yes. Then we probably have an major issue here. I wish my suspecting is wrong.







 







 







Best regards,
