XDG Extended Attributes support

[avidseeker]

XDG Extended Attributes guidelines include metadata about files that are supported on the file system level. Many programs attach this metadata to downloaded or produced files, and it would seem a useful feature to attach some metadata to downloaded files.

youtube-dl supports the following Extended Attributes enabled using --xattrs flag.

user.xdg.referrer.url
user.dublincore.title
user.dublincore.date
user.dublincore.description
user.dublincore.contributor
user.dublincore.format
