Georgi,

Is this an apropos or an insight addition?

My entire position about Linked Data solutions is centered on "User 
Interaction".  Note, I said: "Visualizations are good, but graph 
visualizations are not the sole keys to the treasures that reside within 
a Graph".

I regard "Data Access" as part of "User Interaction".   This is why the 
OpenLink Data Explorer extension (for instance) simply adds the ability 
to "View | Linked Data Sources" to its host browser.  All it is really 
doing is providing the user with a route to a beachead from which a 
query could be beamed (i.e. SPARQL + Full Text under the covers across 
the data sources in it's history).

Give users the  "option" to use their own cognitive skills to interact 
with the data (e.g. pivot, project, and traverse based on their own 
specific needs).

We are repeating a long history of not understanding intersection of 
"User Interaction" and "User Cognitive Skills" if we don't provide 
routes to the data behind subject projections.  This matter has been the 
same since advent of the IT era:

1. Executive Information Systems (what used to be called EIS)
2. Report Writing Systems (Cognos, Crystal Repors, Business Objects, 
Brio,  Forest & Trees, I can go on, used and worked with all of them)
3. Dektop Productivity Tools (Access, MS Query, Paradox, and many more)

"User Interaction" is a about a rich set of options that provide outlets 
for cognitive prowess. Programmers cannot acquire the domain expertise 
of an alien domain.

BTW - I also gave an "User Interaction & Linked Data" talk / demo [2] at 
the most recent Cambridge Semantic Web Gathering.
