Why do we need to change what a "URL" is? Education is a hard lengthy 
and generally arduous process etc..

We simply need to build a bridge from where we are to where we are 
headed using coherent terms etc..

A URL today enables you to locate a Generic Document (it may have a 
myriad of purposes).

What comes next are Descriptor Documents accessible via URLs that have 
the sole purpose of exposing a Structured Description of an Entity (Data 
Object, Data Item, Datum).

URLs don't go away, they just provide us with access to "purpose 
specific documents".

We can "Refer To" and Entity or access its Structured Description via a 
LINK when we construct a Descriptor Document using the EAV Data Model.

Not slippery if we take this moment in time to apply some metaphorical 
sand-paper :-)

Yes, <http://www.w3.org/History/1989/proposal.html> this document is 
much clearer than the latest incarnation of the Linked Data meme IMHO.  
Descriptor Documents are clearly visible in the early TimBL document, 
for sure! The next step should have really been about, what constitutes 
the Descriptor Document such that machines and humans can respectively 
exploit these Descriptor Documents. Again, the answer 
is/was/should-have-been: EAV Data Model.
