I want to be able to use my browser's context menu sequence (CTRL+Right 
Mouse or CTRL+Click) to graph the HTTP URI of the things mentioned in 
the page. This enables me to perform the following once Parallax or 
Sparallax provided me with a beachead within the vast Web of Linked Data:

1. Beam a SPARQL from my current position since I don't have the time to 
click my way down the deep mesh that is the Web
2. Negotiate an alternative representation of the metadata associated 
with the "Thing" or "Things" exposed on the page.

Don't dispute that.

Remember we have:

1. http://lod.openlinksw.com -- questionable UI, but based on the cost 
of the UI, I guess we need to go honker down and fix the darn UI once 
and for all
2. http://ec2.monrai.com:8890/facets/ -- alternative UI to the above
3. 
http://virtuoso.openlinksw.com/dataspace/dav/wiki/Main/VirtuosoFacetsWebService 
-- API used by Razorbase to produce an alternative to our default UI

Depends on what power you are trying to expose.

I am interested in exposing the power of the Linked Data Web which means 
there is never justification to taking HTTP URIs that exist in the 
source data out of the scope of User Agents.

The HTTP URI is the atom. In the Linked Data Web realm its accessibility 
should be sacrosanct.

What about if I don't want to use Javascript or PHP? What then?
