» Dezrann corpus/developer documentation

Dezrann is an open web platform designed to listen to, study, and annotate music. It is used in music education, as well as for corpus annotation in musicology and computational music research. The Dezrann user manual, available in several languages, explains how to use Dezrann. The demos page provides links to pieces showcasing various features.

The technical documentation here is only available in English and covers corpus integration (data formats, corpus creation, curation, quality assessment, and maintenance), translation and localization, and developer information for both front-end and back-end.
