Co-chair meeting minutes: February 24, 2026 [via Music Notation Community Group]

Karim has some ideas for changing the metadata and tools for working with them, so Daniel encouraged him to open issues for those things



MNX



The schema now has an official version number, and the version number is incremented with each revision; it started at 1 and is now at 4 already; issue #497 is thus addressed.



There has been some good discussion about measure indexes, measure numbers, and how you point at measures from other places within an MNX document (issue #447). The indexing part has now been nicely addressed: we previously used a 1-based index for referring to bar numbers. We discussed changing it to being 0-based, but instead we decided to use the measure ID. Multi-measure rests, the measure rhythmic position object, and system (part of the layout infrastructure) now all use IDs.



One remaining thing for measure numbers is the label (issue #501). There has been a spirited discussion about how to encode the label. We don’t yet have a really clear definition of what we’re trying to achieve: it could be more than simple numbers. A couple of suggestions have been made for how this should be encoded. Myke proposes that this is good enough for now, and that we punt issues concerning bar numbering for Broadway and other similar niche cases for the future, or encourage that community to make a proposal that we can include later on.



The next issue to consider is what constitutes a valid ID. We don’t currently provide any info beyond that it should be a string. Our original idea was a simple alphanumeric value, but Robert Patterson pointed out that it would be nice to save MuseScore’s internal ID, which contains other characters. Adrian will make a proposal for issue #503 for this. We briefly discussed whether the string should use only printable ASCII characters, and agreed this is probably sufficient.



Next meeting



The next co-chairs' meeting is scheduled for Tuesday 10 March 2026.
