Re: Update on MusicXML Use Cases

Hi Joe, all,

I've been investigating the 2004 MPEG-4 Symbolic Music Representation 
Use Cases:

The home page for MPEG-4 SMR is at:
http://mpeg.chiariglione.org/standards/mpeg-4/symbolic-music-representation
SMR was going to be part of MPEG-4, but I don't see it mentioned 
anywhere in the white papers at.
http://mpeg.chiariglione.org/white-papers
Has it been dropped? As far as I can see, they are now only looking at 
the synchronisation of subtitles in videos.

My records include a list of the 2004 test cases that required diagrams, 
and (where possible) implementations using /capella 2004/. This list 
does not include the trivial cases, but it does include some interesting 
remarks (see attachment) .

I think the lesson to be learned, is that any future standard must be 
able to cope with everything today's standard editors (/capella/, 
/Sibelius/, /Finale/, etc.) can do, plus some more. I also think it 
should be made easy for such programs to implement any new standard 
(otherwise the standard is going to be ignored).

All such programs can print, so I think it should be fairly 
straightforward for them to export SVG, if they don't already.

===========================

Two new Use Case proposals:

MC11: /Composer of a multimedia work wants to write a score that 
synchronises sound and vision./

C wants to synchronise the sound with the light.This relates to MC0 
("digital encoding" is not restricted to sound), and to MC1 (the C of 
the sounds need not be the same as the C of the lighting.)

and:

ED5: /Instructor wants to use an interactive //Shenker analysis//diagram.

All the best,
James
