- afandian 11y agoPersistent URLs can be opaque. Persistence is more about committing that, for example, the URL structures won't ever change in a backward compatible way.
- greglindahl 11y agoTo explain a bit better: every capture has a crawl time, that time is embedded in the WARC with that capture in it, and that's how the CDX index can refer to that page. Anyone who got our WARCs could easily present the URL structures the same way we do. That time is an essential part of the capture. We worked with others to make sure that the WARC standard does this. This is actually a really important aspect of Wayback links. Since the URL and time are always explicit in the Wayback URL, you don't have to depend on some opaque database to learn important things about that link. An archiving service that just has opaque links is like a bit.ly shortened link: you have absolutely no idea what it is if bit.ly dies.
