I've now updated our Vocabulary page [1] w.r.t. the audio standards:
 + removed AMG/CDDB
 + updated MusicBrainz
 + added MusicXML
Could you please go into detail with MPEG and XMF stuff; and: I'm not so sure how to handle the
Kanzaki and the Foafing vocabularies - any ideas where to put it? (sec. 5 or sec. 6)
Looking at [2] tells me that you _indeed_ have a wiki account (at least you edited your RDF description on 2006-11-14 with it :)
So, please, would you be so kind performing further changes directly on the Voc-page [1]?

Dear Micheal,

Here's a long mail (I do not have a wiki account yet, so please
copy/paste to the wiki whatever you think is useful...)

I would say neither AMG (although they have some interesting taxonomies
with regard to genre/styles) nor CDDB are really vocabularies.
In my opinion ID3 specification is not clear enough (and very wide), the
more concrete thing they propose is a list of genres.
On the other hand, MusicBrainz it is a vocabulary!

Moreover, some of these vocabularies should be taken into account, too
(I've tried to add the categorization proposed whenever it was possible):

* Musicbrainz Schema
MusicBrainz defined an RDFS definition [1] (you can see the HTML output
at [2]). Instances in RDF are available via their query language (see
some results at [3]). An example of their MQ query is:

<mq:artistName>Pink Floyd</mq:artistName>
<mq:albumName>Dark Side of the Moon</mq:albumName>

-- Musicbrainz Discriminator/Category:
Representation RDF (R) / RDFS
Content Type audio (A)
Workflow production
Domain generic
Industry music

[1] http://www.ldodds.com/projects/musicbrainz/schema/index.rdf
[2] http://www.ldodds.com/projects/musicbrainz/schema/mb.html
[3] http://musicbrainz.org/MM/mq_examples.html

* In [4], there are lots of resources about Music Notation and XML. From
the list available in [4], I would like to mention:

+ MusicXML [5], by Michael Good (Recordare).
"Recordare has developed MusicXML technology to create an
Internet-friendly method of publishing musical scores, enabling
musicians and music fans to get more out of their online music."
The DTD specification is available at [6].

-- MusicXML Discriminator/Category:
Representation XML (X) / DTDs
Content Type audio (A)
Workflow production
Domain generic
Industry music

+ MPEG Ad Hoc Group on Symbolic Music Representation, lead by Paolo Nesi
(see [7]) are working on the standarization process of music notation.
Don't know the current status, though.

-- MPEG Ad Hoc Group Discriminator/Category:
Representation XML (X) / DTDs?
Content Type audio (A)
Workflow production
Domain generic
Industry music

The Extensible Music Format (XMF) [8] is a family of music-related file
formats created and administered by the MIDI Manufacturer's Association.
It is based on MIDI files.
Their goal is (quoted from the website):

"Create an open standard file format for gathering together into a
single file all media assets (and/or links to external media assets)
required to render a MIDI note-based piece (or suite of related pieces)
in a computer-based player (or possibly an instrument) with consistent
audio playback across all players and platforms, and suited for
interactivity, content protection, meta-data, and the Internet - and
keep it simple."

[8] http://www.midi.org/about-midi/xmf/

* Then there are other small projects/proposals such as:

+ The Kanzaki music ontlogy [9]
Quoted from the website:
"A vocabulary to describe classical music and performances. Classes
(categories) for musical work, event, instrument and performers, as well
as related properties are defined. Make sure to distinguish musical
works (e.g. Opera) from performance/event (Opera_Performance), or works
(String_Quartette) from performer (StringQuartetEnsemble in this vocab),
whose natural language terms are used interchangeblly. The present
version experiments more precise model to describe a musical work, its
representations (performances, scores, etc) and a musical event to
present a representation (a concert). Includes 30 keys as individuals."

-- Kanzaki Music Performance ontology Group Discriminator/Category:
Representation OWL DL
Content Type audio (A)
Workflow premeditation? / production?
Domain generic
Industry music

[9] http://www.kanzaki.com/ns/music

+ Last but not least, there is the music ontology [10] used by Foafing
the Music project [11]. It includes some descriptors automatically
extracted from the audio (e.g. Key and mode, beats per minute, meter,
intensity, etc.)

-- Foafing the music ontology Group Discriminator/Category:

That's all for now!
