Overview

Variations2 system architecture will provide for storage and delivery of music in formats beyond audio: score images, music notation files, and MIDI files. Mechanisms will be added for authentication, authorization, and access control, as well as storage, search, and retrieval of enhanced administrative and technical metadata.
