Co-chair meeting minutes: May 20, 2026
Daniel, Adrian and Karim were unable to meet, but Karim has provided the following MusicXML update.
MusicXML
The new MusicXML docs site (issue #644) is fully functional and pending some cosmetic fixes before we can deploy it live. We’ve received some feedback already and encourage more users to review it. One specific area where we could use more eyeballs is the changes made to the xsd schema files to move the documentation from the site back into the specific elements/attributes/types:
Milestone 4.1 has been revived and the set of tagged issues is more or less final. I believe I have a good grasp on what needs to be done for each, but I welcome community review of those issues specifically.
Regarding milestones and releases, and given some feedback from Michael Good (@mdgood), I am thinking of targeting multiple minor releases per year, which will include documentation changes and minor edits to the schema such as new enumeration values, new attributes. Deprecations, new elements and other major changes will be kept for major releases once per year or less. I’ve started a Milestone 5.0 to that effect. What’s missing is a “release manual” which lists all the chores needed for a release.
Semantic validation (pull request #627) is stalled and will resume over the summer. The core proof of concept is done (Schematron being the selected technology). A good initial set of validations has been identified, mainly thanks to Werner Lemberg (@lemzwerg). What’s missing is to organize all this in a new “test” area of the repo.
Next meeting
The next co-chairs’ meeting is scheduled for Wednesday 3 June 2026.
