If you site sources using HTTP URIs then the Linked Data meme's implicit 
association of Entity ID and Entity Metadata kicks in i.e., you have a 
timeless
and persistent pointer to the origins of any piece of data exposed by an 
given Data Space (which is the same thing as a *Dataspace*).

My comments are still fundamentally about my preference for CC-BY-SA.  
Hence the transcopyright reference :-)

I want Linked Data to have its GPL equivalent; a license scheme that:

1.  protects the rights of data contributors;
2.  easy to express;
3.  easy to adhere to;
4.  easy to enforce.

As I stated during one of the Semtech 2009 sessions. HTTP URIs provide a 
closed loop re. the above. When you visit my data space you leave your 
fingerprints in my HTTP logs. I can follow the log back to your 
resources to see if you are conforming with my terms. I can compare the 
data in your resource against my and sniff out if you are attributing 
your data sources (what you got from me) correctly.

If all the major media companies grok the above, there will be far less 
resistance to publishing linked data since they will actually have 
better comprehension of its inherent virtues and positive impact on 
their bottom line.

HTTP URIs are potent mediums of value exchange, and for media companies 
they will come to understand that their crown jewels (think "data 
wine")  simply needs to be served up in cyberspace via HTTP URIs instead 
of "paper cups" or electronic renditions of "paper cups"  (e.g. 
newspaper industry).

It's always important to apply temporal context to Ted's comments. The 
guy groked today's Linked Data meme circa. 1965 (or slightly earlier). 
He always espoused interwingularity and hyper-orthogonality of data 
based on inherent irregularity of data structures across Data Spaces / 
Dataspaces.  Xanadu, ZigZag are profound visionary insights that are all 
doable today via applications of Linked Data and RDFa.
