Re: Export from LilyPond to MusicXML (Thomas Morley)

[Jan-Peter Voigt]

Hello Peter,

yes, I still receive the messages from the list, but since I have
changed jobs, my commitment to Lilypond has fallen behind a bit.
But I hope to curate and update my code soon so that it can serve as a
starting point for further development. Of course, Jacque's work should
not be lost sight of, as native support would be nice. But maybe the
scheme-engraver based solution can push the issue a bit.
This topic has been on my mind for quite some time. Since Lilypond does
not offer XML export, its use is problematic in many areas. If I want to
offer something to a publisher, I can't get anywhere with Lilypond in
most cases. If I want to archive the notes in a structured way, I can
come up with 1001 solutions in Scheme that fill a database. But if I
have curated data in MEI format (or MusicXML), I can systematically feed
a database (e.g. eXist) with it and provide a REST API afterwards to
build fancy Webapps.

Best regards,

Jan-Peter
