Hi again Ivo and the Xiph ogg-dev emailing list,
This email is meant to present two blockers for continued development of
the XML based Multimedia Metadata Format (M3F) (MDMF page in the wiki).
This format is intended to replace comments as a way of including
descriptions of metadata contained in the Ogg container format. For
instance title, production year, actors, producers, and so on for movies;
and artist, musicians, labels, and so on for audio. As well as
description relationship between multimedia files; for instance
describing that an image is the albumart of a song. Basically it is
intended to be way more including and extensible than comments.
However development stopped some months ago due to little interest, and
that I did not have the time to continue working all on my on.
Bad news first: The problem with future development is that I do not like
RCFs—I dislike them almost as much as $ man pages—and that I do not have
the time to study technical aspects required to ‘put the format into
action’. I cannot work out the following. so someone will have to step up
and work out these two issues:
* How to include the meta document in the stream?
* How to uniquely identify resources (albumart, songs, subtitles, ...) in
the stream? A note here: Albumart is often stored inside the encoded
files them self (in FLAC at least). How to address those images from a
URI for instance?
The the good news: I can continue the work I originally started: Working
out how to describe various media resources in a format that is both
including and can be expanded (as XML can) when needed.
A tiny note at the end: A better name is Multimedia Metadata Format, or
M3F for short. (.m3f a ‘native file extension’ if it ever appears outside
an Ogg container.). Multimedia Description and Metadata Format (MDMF)
