Put it another way, a specific user may start in the 'D' category then he/she realizes that there is more to achieve if an additional library is used, and can migrate into 'C', using the very same data.

Indeed, A and D are so closely related that I don't really see a 
distinction personally, other than A appears to have no care 
what-so-ever for RDF / Linked Data, so unsure why it's mentioned :p

To me, a good example is: <http://graph.facebook.com/1234>

If you somehow said "stick http://ogp.me/ns# before each property, and 
use the URL as the subject, you've got RDF", then I believe that would 
cover a large portion of the "JSON as RDF" A/D user segments.

Best,

Nathan
