I think John explained it nicely:

"The W3C often assigns a year number as the most significant part of the
URI path 
so that it can be sure that URIs are unique over time, even as parts of
the URI 
                            ^^^^^^^^^^^^^^^^^^^^^^^^^
space are created and destroyed."

What on earth elevated these character sequences to the status of
"metadata" about anything?
