I'll try:

de-referencing an identifier en route to a description (some system 
specific representation of a data structure) at an address dates back to 
the advent of computing.

For instance SQL RDBMS engines do this using keys (Primary, Foreign 
etc..). The problem is that these identifiers are literals and 
de-reference is an act of DBMS engine specific name->address 
indirection. Which is why ever SQL RDBMS that only implements literals 
based identifiers or DBMS specific reference types (as per ORDBMS 
products of yore)  is a data silo vector ++

It's also why all applications developed using existing native (relative 
to host OS and runtime combination) programming language are also data 
silo vectors, since they also use local (or app specific) mechanisms for 
name->address indirection and eventual structured data representation, 
following de-reference.

In a sense, what John is saying to you is as follows:

HTTP URIs are identifiers that make all of the above webby i.e., no DBMS 
specific name->address based indirection, no operating system + 
programming language specific name->address based indirection, it all 
just happens via HTTP URI based hyperlinks which are based on open 
standards (i.e., platform agnostic).

The virtue described above is the kernel of the Web architecture. That's 
what makes it tick. That's why we have a World Wide Web that's dexterous 
enough to handle past, present, and future data access and integration 
challenges without introducing platform specific data silos.

The novelty of HTTP URIs lies in their truly unique ability to enable 
mass data de-silo-fication, at Web-scale.

I hope this helps.
