[uf-discuss] rel-license: what does the license apply to? (open issue revisited)

Although I'm obviously going to agree with that, it strikes me that in
this particular scenario, all you need from RDFa is the @about
attribute.

The example given previously simply becomes:

  <link about="http://example.com/myvideo.flv" rel="license"
href="http://creativecommons.org/licenses/by-nc-nd/2.0/" />

  <link about="http://example.com/myvideo.mov" rel="license"
href="http://creativecommons.org/licenses/by-nc-nd/2.0/" />

I'm suggesting that if people don't want to make the leap to 'full'
RDFa, it still might be worth making use of some of the simpler
features like the about attribute, which are designed to solved
exactly this problem.

By the way, in RDFa 'proper', the @src attribute can also be used to
set the subject, so if the video clips are in an <object> tag, it
could be marked up like this:

  <object src="http://example.com/myvideo.flv" rel="license"
href="http://creativecommons.org/licenses/by-nc-nd/2.0/" />

  <object src="http://example.com/myvideo.mov" rel="license"
href="http://creativecommons.org/licenses/by-nc-nd/2.0/" />

As you can imagine, that's pretty useful for pages full of images,
too, where each image might have a different license.

Regards,
