Neuma
is a digital library that aims at publishing on-line rare corpora of music. This project was initiated by the laboratories CNAM/Cedric and Iremus.
We are currently developing an evaluation framework for qparse integrated in Neuma.
RQ
the OpenMusic library RQ (for Rhythm Quantization) was developped at Ircam in 2015-16 by Adrien Ycart, Jean Bresson, Florent Jacquemard. see this page at Ircam on Rhythmic Notation and Quantification, and more on rhythmic notation, rhythmic quantification and rhythm trees.

The Melisma Music Analyzer
written by Daniel Sleator and David Temperley, it is a system for extracting information from symbolic music content, in particular joint estimation of meter, harmony and streams, a problem highly related to transcription.
A system for piano transcription was recently built on the top of Melisma by Andrea Cogliati and David Temperley.
