A new revision of the Music Ontology has been released today. The main changes have been made to clarify the description of the music creation workflow. We also added the possibility to describe musical shows and festivals.

All in all, the revision 1.11 of the Music Ontology is certainly the most stable and crystallized incarnation of the ontology.

The change log is available here

New projects using the Music Ontology

New projects started to use the Music Ontology to describe musical things. There are a couple of them:

Oscar’s Pendora and Last.fm recommendation system:

Oscar also describe how to:

Yves’s mapping of Magnatune using the Music Ontology.

Also, the Musicbrainz RDF dump using the Music Ontology should be released soon too. I know that I said that it should have been available by this week, however some issues with the rdf views forced me to wait until releasing the dump. I hope having the possibility to make it available by next Monday, as long as with the Virtuoso RDF View files.

Description of the music creation workflow

We also worked hard to clarify the music creation workflow used by the Music Ontology. It is the backbone of the ontology: it explains how people should use the ontology to describes musical things. A complete description of the workflow is available here.



Describing shows and festivals

As discussed on the mailing list, we introduced two new concepts in the Music Ontology: Shows and Festivals. It is now possible to describe where and when a show or a festival will happens, as long as who will give a performance at that event.

Using these new concepts, one could easily describe:

The International Jazz Festivial of Montreal will happens between June 28 and July 8 in Montreal. There will be sub-events at the Spectrum. In fact, there will be a show at the Spectrum the 28 June at 10pm. The performer of that show will be the Dave Holland Quintet.

Then the place of International Jazz Festival of Montreal and the Spectrum will be linked with their Geonames. The Dave Holland Quintet will be linked with their Musicbrainz artist description. All that is possible thanks to the RDF data dumps of each of these services and the Music Ontology.


The Music Ontology evolved greatly in the past few months. Now we have something solid agreed by many people. Many level of descriptiveness are possible and all of them are compatible together. A garage band can now easily describes itself and their records using the Music Ontology. But also, a music expert can describe everything about Beethoven’s Work and all its incarnations played by other musicians over the centuries.
