Hi Lars, thank you for these comments. I have collected my proposed changes based on these comments in https://github.com/cbor-wg/cbor-magic-number/pull/21 > […] > The document, along with other ballot positions, can be found here: > https://datatracker.ietf.org/doc/draft-ietf-cbor-file-magic/ > > > > ---------------------------------------------------------------------- > COMMENT: > ---------------------------------------------------------------------- > > "Abstract", paragraph 1, comment: >> This document defines an on-disk format for CBOR data items that is >> friendly to common on-disk recognition systems such as the Unix >> file(1) command. > > I suggest to not talk about disks or stable storage in this abstract or the > document body. What's actually being defined here is a file layout, and files > can be stored on a variety of media. (And "file" isn't an "on-disk recognition > system" either, it's a heuristic file type classifier.) Indeed. I have replaced “on-disk” by “stored”, and defined “file” for the purposes of this document. (LE 1): Avoid "disk" (-> stored), define “file" https://github.com/cbor-wg/cbor-magic-number/pull/21/commits/8152734 The rest of the comments below is addressed in (LE 2): detailed comments https://github.com/cbor-wg/cbor-magic-number/pull/21/commits/4d17d91 There will be a separate response to the GEN-ART review.
