This non-mapping digital humanities archive, created by musicologists at the Université de Rouen, acts as a repository of chronological performance data. The archive contains over 20,000 event records, which can be searched through topical dossiers or via various authority records such as performing organization, venue, composer, or date. It strikes a compelling balance between being authoritative and open-ended. Researchers can submit data to Dezède that they have compiled on their own in order to build the archive. The archive is rigorous in its citations; all of the data for each event record comes with clearly cited sources. Dezède flexible and designed for both research and pedagogical use.
