Co-chair meeting minutes: July 27, 2026

MusicXML

The updated documentation site is up, and as of the last few days now also has search functionality.

Work is continuing on the test infrastructure. Every commit now goes through a set of test that are meant to validate the schema’s syntax, and tests for the examples included in the documentation. Schematron infrastructure is now also in place, and work is proceeding on coming up with trapping issues that are syntactically valid but semantically incorrect. Karim eventually hopes to document how developers of implementations of MusicXML can use these tests to validate that their application’s export is semantically correct.

Myke Cuthbert has also contributed his fork of the MusicXML test suite to the CG, and that repository has now been moved to the w3c-cg organisation.

In addition to this important infrastructure work, Karim has started working on the roadmap for MusicXML 4.1. He’s made a checklist of everything that would need to go into a pull request for a schema modification: this needs to include not only the schema modification, but also documentation, examples, and so on. Now that he has the process, he’s following it and refining it as he goes. Two or three items have already made it onto the roadmap and he is working on more. This Version History page will be maintained with the changes as they arise.

Karim is also encouraged by the detailed discussions on specific notations, including for improving the representation of ties and slurs. Karim also plans to send a regular update to the public mailing list with progress on specific issues.

Karim has merged in the current state of support for MusicXML to notationref. Our plan is to move the canonical location for the MusicXML and MNX JSON files to their individual repositories.
