Re: Request for review of EmotionML media type: application/emotionml+xml

Hi Bjoern,

Thank you very much for your thoughtful comments.  And very sorry for
the delay.  I was on business travel for a while, and got some trouble
with sending emails after that.

Could you please see inline below for my response?

Sorry but as you pointed out we failed to send out a review request
when we published the Last Call Working Draft.

Thank you for pointing out that, Bjoern.

I've checked RFC4288 at:
 http://tools.ietf.org/html/rfc4288

and think we should say:
[[
Type name:
    application

Subtype name:
    emotionml+xml
]]
instead here.

Thanks.

So the revised version of the EmotionML media type definition should
be the following.  Please note I've added "Applications that use this
media type" field and "Restrictions on usage" field based on the
RFC4288 template.  Also I've split "Author/Change controller" field
into "Author" field and "Change controller" field.

[[
Type name:
    application

Subtype name:
    emotionml+xml

Required parameters:
    None.

Optional parameters:
    charset

    This parameter has identical semantics to the charset parameter of
    the application/xml media type as specified in [RFC 3023] or its
    successor.

Encoding considerations:
    By virtue of EmotionML content being XML, it has the same
    considerations when sent as "application/emotionml+xml" as does
    XML. See RFC 3023 (or its successor), section 3.2.

Security considerations:
    EmotionML elements may include arbitrary URIs. Therefore the
    security issues of [RFC 3986], section 7, should be considered.

    In addition, because of the extensibility features for EmotionML,
    it is possible that "application/emotionml+xml" will describe
    content that has security implications beyond those described
    here. However, if the processor follows only the normative
    semantics of this specification, this content will be
    ignored. Only in the case where the processor recognizes and
    processes the additional content, or where further processing of
    that content is dispatched to other processors, would security
    issues potentially arise. And in that case, they would fall
    outside the domain of this registration document.

Interoperability considerations:
    This specification describes processing semantics that dictate the
    required behavior for dealing with, among other things,
    unrecognized elements.

    Because EmotionML is extensible, conformant
    "application/emotionml+xml" processors MAY expect that content
    received is well-formed XML, but processors SHOULD NOT assume that
    the content is valid EmotionML or expect to recognize all of the
    elements and attributes in the document.

Published specification:
    This media type registration is extracted from Appendix B of the
    "Emotion Markup Language (EmotionML) 1.0" specification.

Additional information:

    Magic number(s):
    There is no single initial octet sequence that is always present
    in EmotionML documents.

    File extension(s):
    EmotionML documents are most often identified with the extensions
    ".emotionml".

    Macintosh File Type Code(s):
    TEXT

Person & email address to contact for further information:
    Kazuyuki Ashimura, <ashimura(_at_)w3(_dot_)org>.

Intended usage:
    COMMON

Restrictions on usage:
    None.

Author:
    The EmotionML specification is a work product of the World Wide
    Web Consortium's Multimodal Interaction Working Group.

Change controller:
    The W3C has change control over these specifications.

Thanks,
