Creating Persistent Links to YouTube Music Videos The document discusses the problem of links to YouTube videos becoming invalid when videos are removed. It proposes introducing a resolver service that redirects links to alternative copies of videos when the original link returns a 404 error. This service would also retrieve and publish metadata about videos to external websites to help find available copies when the initial link is broken. The goal is to create persistent links to YouTube music videos even if the specific video is removed from YouTube.

- 20. 200 Response
- 21. 404 Response
- 22. Metadata Not Found
- 23. ConclusionA 404 response does not mean that YouTube videos like Jessies Girl went away.
- 24. We are working on automating indirection to a service that finds YouTube songs at other URIs.
