Hi WG, Sorry for my late review. This document is quite long. But I think the overall write-up is clear enough. Please see my comments inline: Section 6.1., paragraph 3: > Hence, the event field of ALTO update message can include two sub- > fields (media-type and data-id), where the two sub-fields are > separated by a comma: COMMENT: As the SSE message can support unicode, indicating that the comma is (',', U+002C) may be better. This is also consistent with the character encoding used in other ALTO documents (e.g., Section 10.1 of RFC7285). Section 6.1., paragraph 5: > To allow non-ambiguous decoding of the two sub-fields, the media-type > name used by ALTO SSE MUST NOT contain a comma (character code 0x2c), > and the string before the comma is the media-type name. [To RFC > editor: please check this conforms to Section 4.2 of [RFC6838] and > confirms to IANA.] COMMENT: According to the ABNF of Section 4.2 of [RFC6838], the media-type name can never include a comma. So the "MUST NOT" requirement can be removed. Instead, we can emphasize there is no ambiguity, if necessary. Section 6.2., paragraph 2: > The `data-id` sub-field identifies the ALTO data to which a data > update message applies. For a resource containing only a single JSON > object, the substream-id assigned by the client when requesting the > SSE service is enough to identify the data. In this document, > substream-ids MUST follow the rules for ALTO ResourceIds > (Section 10.2 of [RFC7285]). Substream-ids MUST be unique within an > update stream, but need not be globally unique. For a resource using > multipart/related, the `data-id` sub-field must include the > substream-id, `.` and the unique Content-ID. COMMENT: "must" should be capitalized: the `data-id` sub-field must xxx -> MUST The description "must include substream-id, `.` and the unique Content-ID" is not clear for me. It seems that this document does not just require the `data-id` to include these three components, but be exactly the concatenation of them in order. The latest revision introduces more generic `data-id` to support multipart messages. But I do not see an example to show how to use it. We know path vector is a potential example. Maybe authors do not want to make this document coupled with path vector. Cheers, Jensen On Fri, Dec 13, 2019 at 10:19 AM Vijay Gurbani <vijay.gurbani@gmail.com> wrote: > Jensen: Excellent.
