Hello,

Metalink is an XML format that lists multiple ways (FTP/HTTP/P2P/rsync) to retrieve files, along with checksums and other metadata. It is mostly used by download managers.

Metalink is not restricted to just HTTP, but Lisa Dusseault suggested I post here, looking for "expressions of interest in the basic concept, and volunteers to help with the work (at the very least, reviewers)."

Some basic features the information in a metalink can be used for:
- Listing multiple mirrors for higher availability.
- Automatic error recovery and repair of corrupted downloads.
- Add a file or multiple files to a download queue.
- Share a library of files between filesharing applications.
- Simplified download pages.

For more information:

"Metalink solves the first problem  how to find the most speedy way to download a file  by grouping different download protocols into one protocol. This enables Metalink clients to automatically switch between different mirror servers without explicit user instructions. Not only multiple server information is described but also meta-data (e.g., the location of the server, document tags and license)."
