Co-chair meeting minutes: February 28, 2023


Following the conclusion of the consultation phase (see discussion #292), the co-chairs have decided to proceed with the transition of MNX from XML to JSON. The next steps will be to update the docgenerator tool that is used to produce the MNX specification and examples pages to be able to handle JSON, and then to update the documents themselves to show how the new MNX-based syntax will look. Adrian also plans to update the mnxconverter to produce JSON output.

Myke will look at updating the introduction page of the MNX specification to outline some of the specific advantages that using JSON will bring.


There has been some discussion concerning the use of the score-timewise element (see discussion #483) and Myke proposes that in future versions of MusicXML we should deprecate this approach, since it has never been widely used.

A reminder that there is also a proposal on the table to remove the deprecated DTDs in future versions of MusicXML. The DTDs were deprecated in MusicXML 4.0 and Myke proposes that they should be removed in the next update. If you strongly object to this, please let us know in discussion #481.

Next meeting

The next co-chairs’ meeting will be on Tuesday 14 March 2023.
