ODM is an architectural idea that is to be turned into a specification and a prototype implementation. All this is work in progress. The details can be found in the ODM specification document.
See the licenses page for details.
The main goal of making this public is to get in contact with people for review, comments, proposals, criticism or laughter. Most valued would be cooperation, and there is some hope that in the not-so-far future somebody might want to build actual synthesizers this way.
So, please use the issue page for public communication or send me a mail for a private conversation.
