David,

For purpose of clarity and broader discourse (I know we've been over 
this in private), what is the Linked Data and/or Semantic Web oriented 
value of this very cool visualization?

Put differently, it would be nice if I could beam a query down the data 
graph exposed by you very nice visualization rather than being confined 
to the options presented by your application.

At the very least, what's the harm in exposing the Freebase URLs in 
these Web Pages? If you do that, at the very least, other user agents 
can do stuff with the graphs (Linked Data) that you are visualizing.  
The cost of this little tweak is extremely low and the upside extremely 
high.

Cool stuff for sure, but I would like Parallax to be a nice Linked Data 
Web contribution also :-)  Freebase (basic) is part of the Web, but 
Parallax is sort of confining me to a Freebase enclave by not exposing 
URLs (where I currently see: javascript:{}).


My fundamental argument remains this:

Visualizations are good, but graph visualizations are not the sole keys 
to the treasures that reside within a Graph. Effective traversal (e.g. 
query beaming SPARQL or MQL) is also part of the puzzle, and it would be 
nice if we could always offer the visualization and the 
graph-query-beam-beachhead as part of a single Web information resource 
deliverable. There are always reasons why one or more humans (due 
inherent cognitive prowess) would seek to view the same data 
differently, no matter how compelling the initial visualization, due to 
the fact that data visualizations are inherently subjective projections.

Links:

1. http://tinyurl.com/5of2qu - Abraham Lincoln as Linked Data from 
Freebase  ( I get no triples with Parallax pages since the Freebase Data 
Sources aren't exposed)

Note: The Freebase RDFization Cartridge (Wrapper, Scrapper etc.) will be 
better i.e., right now there are too many literal property values that 
should be URIs (this fix is coming). Ditto proper lookup driven meshing 
with DBpedia.
