Digital Interactive Mozart Edition (DIME)


The core project of the Digital Mozart Edition (DME) is the Digital Interactive Mozart Edition (DIME), which was developed by theStiftung Mozarteum Salzburg (ISM) in collaboration with The Packard Humanities Institute (PHI) in Los Altos/CA. DIME is conceived as an offspring of the Neue Mozart-Ausgabe (NMA) which the Mozarteum Foundation began publishing in 1954 and which has been available as NMA Online since 2006. DIME is based on the NMA and respects the integrity of scholarship and academic achievement of generations of scholars. As an online project, DIME is not identical to the NMA, neither in its content nor its appearance.

DIME is a fully digital edition. The musical texts are encoded in the open, XML-based format of the Music Encoding Initiative (MEI), which facilitates the documentation of editorial decisions and enables the continuous update of the edition. A visualization program transfers the machine-readable XML code to regular music notation. All variants and editorial interventions can be made visible directly in the music. The data format used in DIME allows for a dynamic display of the music adapted to the needs of the user, including the production of individual parts. Not only can the layout-independent coding be displayed on the screen, it is also available for external reuse in other programs (CC BY SA NC 4.0 license).

DIME relies on two strands of editions:

  • ‘Reference Text’: This is a digitally re-mastered representation of the musical text of the NMA, updated and enriched for online display. The ‘Reference Text’ is based on a complete encoding of the NMA provided by PHI. It is synchronized with the NMA Online for reference.
  • ‘Alternative Texts’: These are new editions of selected works chosen according to specific criteria. The ‘Alternative Texts’ are typically source editions based on a single source and are meant as a complement to the NMA ‘Reference Text’.

Part of DIME is the Web Interface MoVi – The Digital Mozart Score Viewer, which is built around the Verovio music engraving library developed by the Swiss RISM office. It offers a variety of features and advanced functionalities for navigation and customized display of the music (for details see the User Manual in MoVi).
