cc Raul - you're the music nerd. How limited is ABC? Is there a Lilypond->ABC converter?

hello,

i have written a new extension to embed music scores in MediaWiki pages: https://secure.wikimedia.org/wikipedia/mediawiki/wiki/Extension:ABC

unlike the Lilypond extension, this uses a simple input language (ABC) that is much easier to validate for security. ABC is mostly used to transcribe Irish trad and other simple tunes, but it recently gained support for more advanced features, e.g. multiple staves and lyrics. this is supported in the extension using the 'abcm2ps' tool.

unlike the existing ABC extension (AbcMusic), it doesn't support opening arbitrary files as ABC input (which is a potential security issue), and has several additional features:

- - The original ABC can be downloaded easily - - The score can be downloaded as PDF, PostScript, MIDI or Ogg Vorbis - - A media player can be embedded in the page to play the media file

i believe the ABC format is suitable for transcribing the majority of scores currently on Wikimedia projects. although it can't handle all of them, it is better than the current situation. plus, as ABC is simple, and existing ABC scores are easily available, it's easier for novice users to contribute.

i would be interested to hear peoples' thoughts on enabling this extension on Wikimedia.

- river.
