JAMS provides:
  • A formal JSON schema for generic annotations
  • The ability to store multiple annotations per file
  • Schema definitions for a wide range of annotation types (beats, chords, segments, tags, etc.)
  • Error detection and validation
  • A translation layer to interface with mir_eval for evaluating annotations
