Re: S5+RDFa + attribution to multiple people

Hi Sergey --

We've had this discussion a few times at CC and decided that the way
we're doing it now more closely models the way the licenses are
actually written (see section 4b of
http://creativecommons.org/licenses/by/3.0/legalcode for one example).

The licenses allow you to specify a name and a URL (where copyright
information may be found) to use when attributing reuse of your work.
The biggest question when you specify more than one attribution
name/url pair (or more than one object) is what that really means --
do you have to attribute them all (which the license legal text
doesn't require -- it just says there should be a single URL) or
choose one (which probably isn't what creators really want)?

I think the key thing to remember is that the CC attribution
information is not intended to be a replacement or proxy for things
like contributor or creator metadata -- it's meant to convey
information which will allow users to comply with the license. As the
creator(s) of a work, you can decide how you want to be attributed and
that should be an explicit, literal string.  I'd argue that in most
cases you'd want both the attribution information as well as more
detailed creator/contributor metadata in a document.

In response to your other inquiries:

* We do have a prototype validator that was developed as part of a
Summer of Code project last year; one of the things on our agenda for
early this year is to finish reviewing that and push it out.
* The behavior you're seeing on the deeds is definitely sub-optimal --
there's a bug open for it
(http://code.creativecommons.org/issues/issue41).
* There's a CC developer mailing list which is as good a place as any
to ask CC metadata-related questions.  See
http://lists.ibiblio.org/mailman/listinfo/cc-devel.
