    History of location-dependence: `TBL ref`_ (like in HT'03 paper)
 
 This can be accomplished by replacing URIs that include
-a server name by location-independent, self-verifying identifiers
-like cryptographic hashes. 
+a server name by URIs that are
+
+- location-independent: do not refer to a particular server
+  that the file is to be downloaded from;
+- semantic-free: don't include human-readable information;
+  if an identifier is semantic-free, there is no incentive
+  to change it when a site is re-designed;
+- self-verifying: after downloading an alleged copy of a document,
+  there is a cryptographical algorithm to test whether
+  this is *really* a copy of this document.
+
+The most prominent example are cryptographic hashes. 
 A file identified by a cryptographic hash
 can be downloaded from any server that has a copy; the client
 can then check the integrity of the file by checking it against the hash.

 In 1996, Tim Berners-Lee [name-myth]_ argued that
-using location-independent identifiers
+using location-independent, semantic-free identifiers
 is not viable on a global scale:
 "[I]f you put information in a name, it decreases its longevity; 
 if you don't you can't dereference it to a resource."
