Creative Commons is currently working on implementation suggestions
for how people can indicate that additional permissions are available
outside the scope of a CC license. We've been referring to this as
CC+ ("CC Plus"). CC+ is a very simple system that associates a "more
permissions" URL with a work. Having this URL in a machine readable
format is very important.
One file format we're looking at is the Atom syndication format, and
we have two different ideas for how we might implement this; I'm
seeking feedback regarding best practices. One option is to use link
with a custom rel; for example:
<link rel="http://creativecommons.org/ns#morePermissions"
href="http://example.com/commercial_license_purchase" />
The alternative is using RDFa
(http://www.w3.org/2006/07/SWD/RDFa/primer) as part of an XHTML
content payload.
You can find examples of both at http://wiki.creativecommons.org/Atom.
Is there a feeling regarding the use of additional <link>s in feeds?
Does most software just throw those away if it doesn't understand the
rel?
Thanks for any feedback;
Nathan
