I'm not quite clear how the nofollow attribute is supposed to work
here. If a feed producer wants to allow automatic downloads, but is
providing the file in multiple formats (only one of which is needed)
how should that be expressed? As you have it at the moment, the client
can't auto-download at all. Should he just leave nofollow off and rely
on the client to download only one?
In this particular example yes. The idea was to demonstrate that there
are means by which smart client behavior can be controlled given the
concerns about potential bandwidth abuse. Dumb clients continue to act
the way they would today.
Also, assuming the title on the main link is supposed to describe the
download file itself, there appears to be no way to inform the user of
the mirror location of the main URI. Without a location name of some
sort, the user can't make an informed decision about which mirror
would be best to use. Perhaps something along the line of Antone's
"label" suggestion might help here.
I could just do this:
<link rel="enclosure" href="http://example.com/softwarepackage.tar.gz";
type="application/x-gzip" x:group="software-package" nf:follow="no" >
<x:mirror href="http://example.com/softwarepackage.tar.gz"; label="Main
Server" />
<x:mirror href="http://example2.com/softwarepackage.tar.gz";
label="California Server" />
<x:mirror href="http://example3.com/softwarepackage.tar.gz";
label="European Server" />
</link>
