Authors,
While reviewing this document during AUTH48, please resolve (as necessary)
the following questions, which are also in the XML file.
1) <!-- [rfced] Please insert any keywords (beyond those that appear in
the title) for use on https://www.rfc-editor.org/search. -->
2) <!-- [rfced] We do believe the capitalized keywords are used in the RFC.
Please review and let us know if any of the capitalized keywords should be
used. Otherwise, we will remove the Terminology section and related
references.
Original:
1.1. Terminology
The keywords MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT,
SHOULD,SHOULD NOT, RECOMMENDED, NOT RECOMMENDED, MAY, and OPTIONAL in
this document are to be interpreted as described in BCP 14 [RFC2119]
[RFC8174] when, and only when, they appear in all capitals, as shown
here.

3) <!-- [rfced] Would you like to include references for the sales data
listed?
Original:
* iPhone (206+ million units sold in 2020): native support for
haptic encoded data
* Android (1.38+ billion units sold in 2020): API support of haptic
buffers
* W3C (HTML vibration API [W3C-Vibration]): Optionally supported in
mobile web browsers. W3C has also defined vibration extensions
for gamepads [W3C-Gamepad]
* Game consoles (39+ million units sold in 2019): MS Xbox, Sony
PlayStation, Nintendo Switch, etc.
* XR devices (9+ million units sold in 2019): OpenXR haptic API

4) <!-- [rfced] May we expand CE as Customer Edge?
Original:
Since they represent the majority of CE devices, a strong
case can be made for 'haptics' as a top-level media type.

5) <!-- [rfced] The text indicates the subtypes have not been
registered by IANA, but ivs is being registered by this document. Please
consider whether updates are needed. Is it correct that ivs is the only
type mentioned in Section 2.5 being registered at this time?
Note: likely different, but we see ogg has been registered as an
application subtype (see
https://www.iana.org/assignments/media-types/application/ogg).
Original:
While these subtypes have *not* been registered with IANA or
standardized (yet), the prevalence of these haptic data formats in a
large number of devices around the world, pre-dating the
standardization of haptic tracks in ISOBMFF, provides a compelling
argument for 'haptics' to be designated as a top-level media type:
Perhaps remove mention of "not been registered with IANA?

Please consider how this text can be updated for accuracy.
Original:
These
codes are not registered yet, but the plan is indeed to standardize
these haptic coding formats in the near future. Once standardized,
these types should also be registered as subtypes of the 'haptics'
top-level media type:

7) <!-- [rfced] For ease of the reader, we have updated "FourCC codes" as
"FourCCs (four-character codes)". Alternatively, may we replace "FourCC"
with "four-character codes", because this is the only place FourCC is used?
Please review.
Original:
The MPEG ISOBMFF proposal included an informative annex of known
haptic coding formats with proposed FourCC codes for them.

as "Ultra-Reliable Low-Latency Communication (URLLC)"? If not, please
indicate how URLL should be expanded.

Instructions for Completing AUTH48
Your document has now entered AUTH48. Once it has been reviewed and
approved by you and all coauthors, it will be published as an RFC.
If an author is no longer available, there are several remedies
available as listed in the FAQ (https://www.rfc-editor.org/faq/).
You and you coauthors are responsible for engaging other parties
(e.g., Contributors or Working Group) as necessary before providing
your approval.
Planning your review
---------------------
Please review the following aspects of your document:
* RFC Editor questions
Please review and resolve any questions raised by the RFC Editor
that have been included in the XML file as comments marked as
follows:
<!-- [rfced] ... -->
These questions will also be sent in a subsequent email.
* Changes submitted by coauthors
Please ensure that you review any changes submitted by your
coauthors. We assume that if you do not speak up that you
agree to changes submitted by your coauthors.
* Content
Please review the full content of the document, as this cannot
change once the RFC is published. Please pay particular attention to:
- IANA considerations updates (if applicable)
- contact information
- references
* Copyright notices and legends
Please review the copyright notice and legends as defined in
RFC 5378 and the Trust Legal Provisions
(TLP – https://trustee.ietf.org/license-info).
* Semantic markup
Please review the markup in the XML file to ensure that elements of
content are correctly tagged. For example, ensure that <sourcecode>
and <artwork> are set correctly. See details at
<https://authors.ietf.org/rfcxml-vocabulary>.
* Formatted output
Please review the PDF, HTML, and TXT files to ensure that the
formatted output, as generated from the markup in the XML file, is
reasonable. Please note that the TXT will have formatting
limitations compared to the PDF and HTML.
Submitting changes
------------------
To submit changes, please reply to this email using ‘REPLY ALL’ as all
the parties CCed on this message need to see your changes. The parties
include:
* your coauthors
* rfc-edi...@rfc-editor.org (the RPC team)
* other document participants, depending on the stream (e.g.,
IETF Stream participants are your working group chairs, the
responsible ADs, and the document shepherd).
* auth48archive@rfc-editor.org, which is a new archival mailing list
to preserve AUTH48 conversations; it is not an active discussion
list:
* More info:
https://mailarchive.ietf.org/arch/msg/ietf-announce/yb6lpIGh-4Q9l2USxIAe6P8O4Zc
* The archive itself:
https://mailarchive.ietf.org/arch/browse/auth48archive/
* Note: If only absolutely necessary, you may temporarily opt out
of the archiving of messages (e.g., to discuss a sensitive matter).
If needed, please add a note at the top of the message that you
have dropped the address. When the discussion is concluded,
auth48archive@rfc-editor.org will be re-added to the CC list and
its addition will be noted at the top of the message.
You may submit your changes in one of two ways:
An update to the provided XML file
— OR —
An explicit list of changes in this format
Section # (or indicate Global)
OLD:
old text
NEW:
new text
You do not need to reply with both an updated XML file and an explicit
list of changes, as either form is sufficient.
We will ask a stream manager to review and approve any changes that seem
beyond editorial in nature, e.g., addition of new text, deletion of text,
and technical changes. Information about stream managers can be found in
the FAQ. Editorial changes do not require approval from a stream manager.
Approving for publication
--------------------------
To approve your RFC for publication, please reply to this email stating
that you approve this RFC for publication. Please use ‘REPLY ALL’,
as all the parties CCed on this message need to see your approval.
