W3C PROV-compliant provenance tracking for media archives using the Entity-Activity-Agent model in JSON-LD format.
A media file — the thing being tracked.
A transformation — download, transcode, tag, extract audio.
A tool or person — yt-dlp, ffmpeg, opustags, the curator.
Media files often go through multiple transformations:
YouTube video (Entity)
→ downloaded by yt-dlp (Activity, Agent: yt-dlp)
→ raw .mkv file (Entity)
→ audio extracted by ffmpeg (Activity, Agent: ffmpeg)
→ raw .opus file (Entity)
→ tagged by opustags (Activity, Agent: opustags)
→ final .opus file (Entity)
Each step is recorded with timestamps, tool versions, and parameters.
