JAMS: A JSON Audio Metadata Standard

JAMS is a Python library implementing a JSON-based music annotation format, providing a formal schema for generic annotations. It allows for storing multiple annotations per file and includes schema definitions for a wide range of annotation types like beats, chords, segments, and tags. The library also features error detection, validation, and a translation layer to interface with `mir_eval` for evaluating annotations. It is actively maintained, with the current version being 0.3.5, and supports recent Python versions.
