Issues

ISSUE-305 [Profile short names] (pending review)
  • 2014-10-16 13:45:43:
    *<Glenn Adams> Issue dissociated from any product
    *<Glenn Adams> >Here's where I think we're up to with a restated requirements list for this feature, as a straw man:
    >
    >1. Provide information external to a document D to allow a system to decide 'can I process this document'.

    In general, this is not possible by simple examination of an externally signaled profile designation. The reason being that a document may semantically extend/restrict such external designation, or may specify processor profile requirements that do not correspond to such external designation.

    In other words, a conforming processor must still process the internal profile specifications in order to determine if a document can be processed.

    >1a. Signal permitted processor profiles.

    Not sure what "permitted" means.


    >1b. Provide rules for inferring processors from content profiles.

    This is now specified for internal profile semantics processing.

    >2. Allow the system to select/initialise an appropriate processor P for processing the document.

    This seems the only legitimate role of an external designation.

    >3. Map the information into the profile and feature definitions that can be expressed within a document.

    Not a requirement. Handled by internal profile mechanism.

    >4. The signalling to be as concise as possible. (i.e. if a simpler scheme allows for more concision it would be preferred since fine grained precise data is more verbose and is not needed).
    >5. Format must be permissible in both MIME type and @codecs parameter.
    >6. Allow non-W3C recommendation profiles of TTML to be signalled.
    >7. Registration process must be defined.

    >And in the 'not a requirement' list:
    >X. Facilitate generic XML processing, e.g. BiM coding.
ISSUE-335 [Negative times for offsets] (pending review)
ISSUE-351 [Update IANA registration for TTML2] (raised)
  • 2014-10-17 09:46:47:
    *<Nigel Megitt> Created issue 'Update IANA registration for TTML2' nickname Update IANA registration for TTML2 owned by Nigel Megitt on product TTML2, description 'Update the MIME type registration for TTML with IANA to include the processorProfiles parameter with syntax as described in the Codecs Registry page [1].

ISSUE-352 [Add Media Registration Annex] (raised)
  • 2014-10-17 09:47:45:
    *<Nigel Megitt> Created issue 'Add Media Registration Annex' nickname Add Media Registration Annex owned by Nigel Megitt on product TTML2, description 'When Issue-351 has been completed, add a Media Type Registration Annex to TTML2 that reflects the updated registration, similar to what's in Annex C of TTML1.
    ' non-public
ISSUE-353 [Normatively define short code processorProfiles parameter] (raised)
  • 2014-10-17 09:58:46:
    *<Nigel Megitt> Created issue 'Normatively define short code processorProfiles parameter' nickname Normatively define short code processorProfiles parameter owned by Nigel Megitt on product TTML2, description 'The ttp:processorProfiles parameter, to be used within in TTML2 documents, is already defined. A similar processorProfiles parameter for use externally to TTML2 documents, using registered short codes and syntax similar to that described in https://www.w3.org/wiki/TTML/CodecsRegistry is needed within the TTML2 specification as well, so that it can be normatively referenced.

    This is a pre-requisite for updating the IANA registration of the MIME type, Issue-351.' non-public
