Alan,

Which license simply allows me to assert that I want to be attributed by 
data source URI. Example (using DBpedia even though it isn't currently 
CC-BY-SA):

I have the URI: <http://dbpedia.org/resource/Linked_Data>. If you use 
this URI as a data source in a Linked Data meshup of Web 2.0 mashup, I 
would like any user agent to be able to discover 
<http://dbpedia.org/resource/Linked_Data>. Thus, "Data provided by 
DBpedia" isn't good enough because the path to the actual data source 
isn't reflected in the literal and generic attribution.

The point above is the crux of the matter for traditional media 
companies (today) and smaller curators of high quality data (in the near 
future). Nobody wants to invest time in making high quality data spaces 
that are easily usurped by crawling and reconstitution via completely 
different URIs that dislocate the originals; or even worse, produce 
pretty presentations that complete obscure paths to original data 
provider (what you see in a lot of Ajax and RIA style apps today).
