open-dj keeps DJ libraries from arguing with each other

Field notes

The project addresses a practical compatibility problem among rekordbox, djay, Serato, and Traktor by treating library metadata as portable records. Its format attaches source and timestamp information to values including BPM, key, cues, and ratings, allowing conflicting analyses to be merged deliberately. The page also describes cross-machine storage of stem-separation and vocal-detection results, while stating that library data remains on the user's machines. No download or demonstration is visible on the homepage.
