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.

This way, a page's URI never needs to change.>>>
In 1996, Tim Berners-Lee [name-myth]_ argued that

+using location-independent, semantic-free identifiers

"[I]f you put information in a name, it decreases its longevity;
if you don't you can't dereference it to a resource."
