The Entity-Relationship model is actually deeply to connected to what 
Linked Data is all about. That's my fundamental point. Unfortunately, 
the connection is lost due to terminology choices in a lot of W3C and 
Web related literature.

Resource is an overloaded term. Entity isn't an overloaded term.

But that isn't the essence of what Dret is outlining. He is stating that 
a URIs can unambiguously identifies two resources in a 'describes' 
relationship. That isn't the same as stating that a URI can resolve to a 
variety of representations. Far from it.

The very problem I am trying to avert is already playing out in your 

At this juncture you believe that the  "information resource" and "non 
information resource" distinction (which has been problematic for years) 
trumps the clarity of the term "entity" which basically implies 
anything, irrespective of realm, in existing technical and non technical 

Ultimately, there's no benefit in following a broken path for the sake 
of not ruffling feathers. Terminology should always seek to bridge 
existing work across connected realms. Thus far, poor terminology 
choices have remained the biggest hurdle to comprehending most 
initiatives associated with Linked Data, RDF, and the Semantic Web in
