Ordinary authors can use a 303-redirect service like
http://thing-described-by.org/ to avoid having to configure their
servers.  This technique can also be combined with the  use of PURLs, so
that the "http://thing-described-by.org?" prefix does not have to appear
in ontologies.

For example, this PURL URI for me:
  http://purl.oclc.org/NET/DBOOTH/id/dbooth  
302 redirects to:
  http://thing-described-by.org?http://dbooth.org/2005/dbooth/ 
which 303-redirects to:
  http://dbooth.org/2005/dbooth/

Creation of that PURL required only registering it at purl.org.  No
configuration was done at dbooth.org and no registration was needed at
thing-described-by.org.

Of course, if purl.org also offered 303 redirects instead of only 302's
-- are there any OCLC folks listening? -- this could all be done in one
step instead of two.  Note also that with purl.org's "partial redirect"
feature (see
http://purl.org/maint/choose_redirect.html ) multiple URIs in an
ontology do not have to be registered individually at purl.org.

Come to think of it, shouldn't this be covered in the "Cool URIs for the
Semantic Web" document, given that: (a) a 303-redirect service can
significantly reduce a barrier to adoption; and (b) persistence is an
important element in creating "Cool URIs for the Semantic Web"?
