I agree with that, but it only covers a small portion of what is needed. You
fail to consider the situations where people publish data about other
people's URIs, as reviews or annotation. The foaf:primaryTopic mechanism
isn't strong enough if the publisher requires full attribution for use of
their data. If I use SPARQL to extract a subset of reviews to display on my
site then in all likelihood I have lost that linkage with the publishing
document.

The BBC is a traditional media company. Its data is licensed only for
personal, non-commercial use: http://www.bbc.co.uk/terms/#3

I found this linked from the RDF Distribution page on neurocommons.org :
http://svn.neurocommons.org/svn/trunk/product/bundles/frontend/nsparql/NOTICES.txt

Everyone should read it right now to appreciate the complexity of
aggregating data from many sources when they all have idiosyncratic
requirements of attribution.

Then read
http://sciencecommons.org/projects/publishing/open-access-data-protocol/ to
see how we should be approaching the licensing of data. It explains in
detail the motivations for things like CC-0 and PDDL which seek to promote
open access for all by removing restrictions:

"Thus, to facilitate data integration and open access data sharing, any
implementation of this protocol MUST waive all rights necessary for data
extraction and re-use (including copyright, sui generis database rights,
claims of unfair competition, implied contracts, and other legal rights),
and MUST NOT apply any obligations on the user of the data or database such
as “copyleft” or “share alike”, or even the legal requirement to provide
attribution. Any implementation SHOULD define a non-legally binding set of
citation norms in clear, lay-readable language."

Science Commons have spent a lot of time and resources to come to this
conclusion, and they tried all kinds of alternatives such as attribution and
share alike licences (as did Talis). The final consensus was that the public
domain was the only mechanism that could scale for the future. Without this
kind of approach, aggregating, querying and reusing the web of data will
become impossibly complex. This is a key motivation for Talis starting the
Connected Commons programme ( http://www.talis.com/platform/cc/ ). We want
to see more data that is unambiguously reusable because it has been placed
in the public domain using CC-0 or the Open Data Commons PDDL.

So, I urge everyone publishing data onto the linked data web to consider
waiving all rights over it using one of the licenses above. As Kingsley
points out, you will always be attributed via the URIs you mint.
